This study was cross-sectional and only associations can be observed, therefore any inferences about causality cannot be made. Overall, these data suggest that T and the nutritional status directly modulate RBC function, and whether RBC aggregation directly influences T biosynthesis remains unknown. On the other hand, T may increases RBC susceptibility to hemolysis possibly through osmotic and oxidative hemolysis . Hazelnut consumption improves testicular antioxidant function and semen quality in young and old male rats. Effect of omega-3 and omega-6 polyunsaturated fatty acid enriched diet on plasma IFG-1 and testosterone concentration, puberty and semen quality in male buffalo. Sexual maturity and fertility-related measures in young Nellore bulls receiving long-term dietary supplementation with rumen-protected polyunsaturated fatty acids. Such an intention is due to the crucial function of testosterone as the major sex hormone in males . Several in vivo trials have utilized different dietary supplements and medicinal plants to enhance testosterone production in males. Enhancing and protecting testosterone production is one target for many scientists because of its crucial role as a primary sex hormone in males. To consume it, prefer organic and cold-pressed juice. Additionally, it has been suggested that figs may increase libido due to their richness in amino acids. Their fiber content also supports digestive health and hormonal balance. The tangy sour taste of Pineapple always becomes the most preferable choice when it comes to juice. Additionally, Pomegranate juice contains compounds that boost the synthesis of an enzyme system (eNOS) that produces nitric oxide. Indeed, Pomegranate is a nutrient-dense fruit that has plenty of health benefits. Nitric oxide is a signaling molecule that plays a crucial role in vasodilation, which is the widening of blood vessels. When it comes to their food intake, some of the most preferable beverages are juices and smoothies. Bahrami N, Goudarzi M, Hosseinzadeh A, Sabbagh S, Reiter RJ, Mehrzadi S. Evaluating the protective effects of melatonin on di(2-ethylhexyl) phthalate-induced testicular injury in adult mice.

A european carotenoid database to assess carotenoid intakes and its use in a five-country comparative study. Additionally, it is a superfood rich in vitamins and minerals that also happens to be one of the foods that raise testosterone levels. The body produces more testosterone in the testes as a result of elevated LH levels. Ginger juice contains compounds that have anti-inflammatory effects, potentially reducing inflammation in the body. To answer that, we did in-depth research that claims that citrus fruits may help boost testosterone levels. Hydration also ensures the body’s systems function optimally, contributing to more energy and better stamina during sexual activity. By helping the body stay hydrated, watermelon indirectly supports overall sexual performance. In a study published in the journal Urology, researchers found that citrulline supplementation significantly improved erectile function in men with mild ED. Some studies have suggested that consuming citrulline-rich foods like watermelon can help reduce mild to moderate ED symptoms by enhancing blood flow to the penis. Three studies were randomized controlled trials (39, 48, 54) and 1 study was a randomized, double-blind, placebo-controlled trial (61). Two of the studies demonstrating positive effects recruited men with no known clinical conditions (50, 62). Three studies used a randomized, double-blind, placebo-controlled study design (35, 51, 62), and 1 study used a randomized, double-blind, placebo-controlled, crossover study design (50). Medicines such as opiate painkillers and steroid injections also can cause low testosterone. A man’s testosterone level peaks in early adulthood, around the age of 30, and declines naturally with age. It affects a man’s appearance, muscle size and strength, sperm production, and sex drive. What Are the Health Benefits of Eating Testosterone Boosting Fruits for Men? But it should not be replaced with medical treatment for erectile dysfunction. It may offer gentle support for erectile health when eaten consistently and wisely. Watermelon is good for erections, but only when combined with other healthy habits. Always consult a healthcare professional if you're experiencing ED. These contribute to oxidative damage that decreases the serum testosterone level. Try making some juice to boost your low test level by mixing fruits and veggies known to have benefits for low testosterone. Eating T-boosting fruits can also help prevent several health conditions like prostate cancer, colon cancer, and erectile dysfunction. hour ambulatory blood pressure monitoring (ABPM). Let’s explore the dynamic synergy between these nutrient-packed beverages and the mechanisms that influence testosterone levels in the human body. In recent times, a growing body of research has spotlighted the potential impact of certain dietary choices on testosterone production. It helps you produce more ‘good’ rather than ‘bad’ estrogens, which in turn allows the body to maintain healthier levels of testosterone. She showedthat the animals treated with pulp extractions presented the lowerincreases on testosterone levels, and the animals treated with anextraction of the seeds showed the greatest increase compared to theother groups. Kolawole etal., also used the lead acetate at a dose of 2.25 mg/kg to stimulioxidative stress on the animals, and observed a decrease of 50% atthe testosterone levels of the animals receiving lead acetate comparedto the control group. The researchersin the studies measured the testosterone levels before and after thetreatment period, the treated group was compared with the controlgroup, in order to observe the effect of the treatment. Her graduate research focused on the role of specific bioactive compounds on cognitive function and longevity. In 2016, she was recognized university-wide for supporting the scientific careers of female trainees and colleagues (Becky Trigg Outstanding Woman UAB Faculty Member) and nationally for making significant contributions to gerontological research (M. Powell Lawton Award). Her primary area of research focuses on social and environmental factors, including the role of social support on influencing health-related behaviors and outcomes, especially those related to eating. Vinoth also developed various voice call and text application which are used to monitor participants’ performance while in research studies. Can eating watermelon alone significantly raise testosterone levels? If you’re concerned about your testosterone levels, it’s wise to consult with a healthcare provider. Higher levels of body fat can lead to lower testosterone levels, creating a cyclical problem. Low testosterone levels in men affect sexual desire and mood, as well as muscle mass. Between the ages of 11 and 13, testosterone production increases, causing changes such as the growth of the Adam's apple and the appearance of body hair, beard and moustache. Adequate testosterone levels are linked to better mental health and emotional well-being. This study provides valuable insight regarding the potential of 100% watermelon juice as a preventative food-first intervention to affect vascular health of postmenopausal women. Let’s explore five ways watermelon can boost your testosterone naturally, supported by current research and nuanced insights. For many, the answer might hinge on testosterone—an essential hormone driving energy, mood, and even muscle strength. This study was supported by the deanship of research at Jordan University of Science and Technology. Similarly, in a prior study, Shanely et al reported no changes in fasting blood glucose, insulin, or HOMA-IR among overweight and obese postmenopausal women after six-week supplementation of watermelon puree . The juice intervention resulted in a statistically significant increase in fasting serum glucose; however, increases were not clinically significant as levels were well below diagnostic for impaired fasting glucose . These studies attributed the effects of watermelon on vascular function to the arginine and citrulline. Compared to an isocaloric placebo beverage, juice supplementation resulted in a slight but significant increase in fasting blood glucose; however, impact on glucose homeostasis was not clinically significant. Sometimes, however, testosterone levels drop more than they normally should. Your testes produce testosterone, but your brain and pituitary gland control the levels in your body. Although women make smaller amounts of it in their bodies, testosterone is the major male sex hormone. Often, diet and lifestyle changes often can help avoid low testosterone and support healthier levels. There are many causes for a drop in testosterone levels. It also has the function of maintaining libido or sexual desire. This hormone, produced in the testicles and a small amount by the adrenal glands, is necessary, among other things, for producing sperm, developing facial and body hair, a deep voice and muscle strength. As science advances, new ways to optimize hormone levels naturally are discovered. How much watermelon would you have to eat every day to match the dose they used in the study? “Oral L-citrulline supplementation improves erection hardness in men with mild erectile dysfunction.” Improving Gut Health and Hormones As interest in natural health solutions grows, many are turning to plant-based proteins for their potential benefits. It could also be explained by thelower levels of antioxidants found on the pulp of the fruit, as showedby in her master’s degree thesis. At a similar study the animalsreceived one single dose of an injection with alloxan at 150 mg/kg toinduce diabetes. They showed values of testosterone almost10x higher compared to the control group in both treated groups, andthere was no difference between groups. At another study using rind extract, were tested 500 mg/kgand 1000mg/kg in rats. These compounds improve blood vessel function and protect against oxidative stress. Zinc plays an important role in testosterone production and magnesium effectively relaxes blood vessels. Salmon, mackerel, sardines, and tuna are loaded with omega-3 fatty acids which improve cardiovascular health and increase blood circulation. Its high concentration of quercetin helps maintain testosterone levels. Rich in healthy fats and vitamin E and vitamin D, They are an excellent source of monounsaturated fat, with benefits that affect the hormonal production of testosterone. Without a doubt, it is a natural and delicious option for male sexual health and wellness. Studies indicate that fruits are foods that help improve people's mood and reduce anxiety, which also contributes to more optimal testosterone levels. To prevent testosterone deficiency, or to increase it when it is low, it is necessary to follow healthy lifestyle habits, including diet. Levels of l-arginine and l-citrulline in patients with erectile dysfunction of different etiology (D) No difference in serum PSA levels was observed between the control and ME-administered groups. From these results, we concluded that the administration of ME and FME could enhance the testosterone production capacity in aging rats and that andropause symptoms caused by a deficiency in testosterone might thus be relieved by administration of these extracts. Next, the effects of ME and FME on testosterone secretion in vivo were investigated by administrating these extracts to aged rats daily for 6 weeks (Fig. 1A). After fermentation, the total polyphenol and flavonoid contents were increased approximately 1.7 and 1.6 times, respectively, in FME compared to those in ME (Table 1). Since the fermentation of lactic acid bacteria can change the content of physiologically active components in MC and increase useful physiological activity, the total polyphenol and flavonoid contents of ME and FME were compared. Apart from this, watermelon is also a good source of vitamins A, C, and B6 and potent antioxidants that incredibly support optimal testosterone growth in men.The paucity of high-quality studies investigating the effects of herbs on testosterone production in men means further research is required.Physiological doses of watermelon juice and the washout period between arms were determined by previous watermelon studies 33, 34.The accurate mechanism of MEs decreasing SHBG concentrations has not yet been studied, and thus, further research on this topic may be needed.Protective effects of l-arginine against testosterone synthesis decreased by T-2 toxin in mouse Leydig cells.Studies indicate that fruits are foods that help improve people's mood and reduce anxiety, which also contributes to more optimal testosterone levels.Could zinc prevent reproductive alterations caused by cigarette smoke in male rats?These foods improve blood circulation, support heart health, and naturally enhance sexual performance by boosting nitric oxide and testosterone levels.A health history questionnaire was used to collect information of participants on age, sex, nationality, religion, smoking behavior, alcohol consumption, medical history, recent medication (hormone therapy, iron supplementation), and alcohol abuse.Lanatusrind was able to increase testosterone above the levels observed atthe control group and also increased significantly the testosteronelevels of the lead acetate group, confirming the results showed byGodspower et al., . Another compound called Bromelain in watermelon has the ability to increase testosterone count in males which raises their cravings for sex. They increase libido and regulate estrogen and testosterone levels with Vitamins A and C. This sweet tropical fruit is jam-packed with vitamins and minerals to increase testosterone levels and even improve your sex drive. It's important to remember that testosterone production is influenced by various factors, including diet, exercise, sleep, and stress levels. FOODS THAT NATURALLY INCREASE TESTOSTERONE LEVELS In this review, Asian ginseng only had 1 study out of 7 demonstrating a positive effect on testosterone concentrations in men; however, its administration reduced cortisol concentrations in adults experiencing high work stress (78). Moreover, the testosterone-enhancing effects identified in the single study on forskohlii (40) are consistent with the results of an animal study where reproductive toxicity in rats, induced by the pro-oxidant mancozeb, was attenuated by forskohlii supplementation, potentially resulting from its antioxidant properties (84). Additionally, all studies examining the effect of maca on testosterone concentrations have previously been reviewed by Gonzales et al. (70) and were determined to not affect serum concentrations of testosterone. In support of the findings of this review, a recent meta-analysis of clinical trials on fenugreek seed extract supplementation reported a significant increase in testosterone concentrations (68). Fenugreek seed extracts (positive findings in 4 out of 6 studies) and ashwagandha root and root/leaf extracts (positive findings in 3 out of 4 studies) demonstrated the most consistent increases in testosterone concentrations. Feeding hydroalcoholic extract powder of Lepidium meyenii (maca) increases serum testosterone concentration and enhances steroidogenic ability of Leydig cells in male rats. Effect of different levels and sources of zinc supplementation on quantitative and qualitative semen attributes and serum testosterone level in crossbred cattle (Bos indicus x Bos taurus) bulls. Sönmez M, Türk G, Yüce A. The effect of ascorbic acid supplemen-tation on sperm quality, lipid peroxidation and testosterone levels of male wistar rats. Testosterone promotes increased muscle mass and strength. Three and a half servings a day—unless you eat yellow watermelon, which has about four times as much citrulline. But there’s another way to boost cGMP levels, by going to the other side of the equation, and stimulating the enzyme that makes it. So, enzyme inhibition means more cGMP, which means more blood flow. It's worth noting that most research on testosterone boosters focuses on isolated compounds rather than whole food sources like watermelon seeds. This high protein content, combined with the zinc and magnesium, creates a potentially powerful trio for supporting hormone health. It's an essential mineral that the body cannot produce or store, making dietary intake vital. One of the key reasons why watermelon seed protein has caught the attention of health enthusiasts is its impressive mineral content, particularly zinc and magnesium. The studiesthat treated animals with different concentrations were consideredas different studies to the meta analysis (Figure 2) to consider theimportance of the dosage. But, other than that, it can also rev-up test production. This article reviewed the top 5 best testosterone-boosting fruits AND MORE! While there are many ways to enhance test levels, eating a balanced meal with nutrient-dense foods is a natural go-to. Thisstudy was carried out by searching the main databases available through thekeywords “Citrullus lanatus” and “testosterone”. Are there any side effects of consuming too much watermelon? They can offer personalized insights tailored to your health needs, ensuring you approach testosterone health holistically. Integrating watermelon into your diet offers several avenues to support testosterone naturally, from its citrulline content to hydration and antioxidant properties. Watermelon’s low-calorie and non-fat profile makes it an excellent snack for those looking to maintain or lose weight, which can support testosterone production. Similarly, previous studies showing improvements in vascular measures with watermelon supplementation have included overweight and hypertensive individuals 9–14, 28. Prior studies also reported antihypertensive effects and improved endothelial-dependent vasodilation with supplemental lycopene . However, despite increases in serum lycopene, we did not observe changes in any vascular measures. Future pharmacokinetic studies are also indicated to assess the bioavailability of watermelon’s bioactive compounds among individuals of different ages and body composition. Discordant results may relate to differences in processing as most previous studies have used watermelon juice that was not pasteurized 33, 61–63. It is well-known that the vasodilation effect of NO increased blood flow in the blood vessels 58,59. The study conducted on alloxan-induced diabetic rats by Ghlissi et al. in 2013 showed that 1.5 g of fresh ginger per 15 g of rat diet, for 30 days, significantly reduced the level of blood glucose . Furthermore, in diabetic conditions, other than its potential antioxidant effects in the testes, ginger roots have been found to have a direct effect on blood glucose . The decrease in GSH level reduces the detoxification process for prooxidants in the testes, which negatively affects the testosterone production . The evidence above explains why the majority of studies that demonstrate the effect of ginger on testosterone were conducted on diabetic rat models. You may have heard that watermelon can be beneficial for the penis—perhaps even improving sexual performance.Excess levels of stress in the body cause a decline in testosterone levels and may lead to other adverse complications to health.It is in the group of fruits called dark berries, recognized for their nutritious and healthy properties, as they are rich in antioxidants.In matters concerning sexual health, individuals tend to think of common supplements and medicines when they cannot consider the goodness of natural products.In conclusion, the FME showed a positive effect on male climacterium symptoms, and thus, it is expected that such extracts can be developed as a functional material or food that is effective in alleviating andropause.The juice intervention resulted in a statistically significant increase in fasting serum glucose; however, increases were not clinically significant as levels were well below diagnostic for impaired fasting glucose .Well, considerably all the juices of fruits and vegetables are safe to combine in a diet, but if you’re allergic to any particular, we suggest avoiding that juice.These results are promising, but they are based on animal studies. This study is the first of its kind to investigate the relationship between consumption of 100% watermelon juice and changes in cognitive performance, oxidative stress, and inflammation. 6 Despite largely null findings reported herein, 100% watermelon juice is indeed an effective vehicle for bolstering serum lycopene. 17 However, two daily 360 mL doses of 100% watermelon juice for a four-week period did not show appreciable effects on measures of cognition, oxidative stress, or systemic inflammation. Watermelon is a rich source of citrulline, which has been found to improve erection hardness in men with mild erectile dysfunction (impotence). Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Amy Ellis, PhD, RD and Kristi Crowe-White, PhD, RD are Co-Principal Investigators who contributed equally to the design and management of this study. So, although this study was powered to detect changes in other outcomes, a larger cohort may be necessary for the outcome measure of FMD, especially considering the large inter-individual variation observed for this outcome. Because the glycemic index of fruit juice is higher than that of whole fruit, there is also concern that juice may negatively impact glucose homeostasis . Bromelain maintains the concentration of testosterone levels (4). Good nitric oxide levels promote vascular activity and enhance blood flow in the body. We rounded up the five best T-boosting fruits to boost testosterone levels, all for you! The high zinc and magnesium content, combined with quality protein and other nutrients, make watermelon seeds a promising addition to a balanced diet aimed at supporting overall health and potentially hormone balance. Possible drawbacks of juice consumption relate to its concentrated sugar content and concerns that it may provide excess kilocalories without concomitant satiety . Because of the many conjugated double bonds in its structure, lycopene has strong antioxidant activity . Unlike arginine and citrulline, lycopene cannot be synthesized endogenously, so it must be consumed in the diet . A fasting blood sample was obtained to quantify serum levels of lycopene, citrulline, arginine, and ADMA. So, any intervention study should also consider effects of juice on body composition and glucose homeostasis. Although watermelon is purported to be a functional food for vascular health, pragmatic approaches for real-world dietary interventions are lacking. Kataoka T, Hotta Y, Maeda Y, Kimura K. Testosterone deficiency causes endothelial dysfunction via elevation of asymmetric dimethy-larginine and oxidative stress in castrated rats. Watermelon Viagra refers to watermelon’s potential to help with erections due to its citrulline content, which supports blood flow. Yes, watermelon contains citrulline, which may help improve blood flow and support better erections naturally. Overall, 9 out of 32 studies demonstrated significant increases in testosterone concentrations. One randomized, double-blind, placebo-controlled study was conducted examining the effects of cordyceps (manufactured by a submerged culture technique with the mycelia spray-dried to obtain a powder) on testosterone concentrations (44). One randomized, double-blind, placebo-controlled study was conducted examining the effects of a longjack extract (Physta®, manufactured by Biotropics; freeze-dried water extract) on testosterone concentrations (45). A Review of foods and food supplements increasing testosterone levels A systematic review in Obesity found that weight loss can lead to improvements in testosterone levels in obese men (Travis et al., 2022). Maintaining adequate hydration can help optimize the body’s physiological functions, including hormone regulation. By lowering oxidative levels, antioxidants like lycopene may preserve the integrity of reproductive tissues, thus providing a more favorable environment for hormone synthesis. Therefore, by using TM3 Leydig cells, we analyzed whether ME and FME could regulate the expression of genes related to testosterone synthesis and degradation. The collected sperm were first diluted in 32 °C M199 medium to make the environment similar to that of the interior of the body and thus to improve the survival rate. The epididymis on the left and right sides of the experimental rats were extracted, chopped with surgical scissors, and cultivated for 10 min in 4 mL of M199 medium containing 0.5% bovine serum albumin, which was preheated to 37 °C, and then sperm were collected. Thus, it appears that ME or FME administration does not cause side effects of PSA elevation in the prostate that may occur with testosterone replacement therapy. The free testosterone level of the control group was 0.75 ± 0.11 pg/mL, while the levels in the experimental groups were 1.06 ± 0.21 pg/mL, 1.59 ± 0.18 pg/mL, 1.50 ± 0.17 pg/mL and 2.23 ± 0.13 pg/mL with the ME20, ME40, FME20 and FME40 treatments, respectively (Fig. 1C). In summary, at the same dosage, FME administration showed a stronger effect than ME on the reduction in SHBG levels and was deemed to retain a level of bioactive free testosterone that was higher than that in the control group. Therefore, the concentration of free testosterone, which is not combined with SHBG, is more important than the concentration of total testosterone with respect to testosterone deficiency (Shea et al., 2014). Consuming excessive watermelon can lead to digestive discomfort due to its fiber and water content. Incorporating a moderate amount—like 1-2 cups of diced watermelon a few times a week—can be beneficial without overdoing it. How much watermelon should I eat to reap benefits? Remember that while watermelon can be beneficial, it’s most effective as part of a broader lifestyle strategy that includes regular physical activity and balanced nutrition. Testosterone and body fat percentage are closely linked. Pomegranates - Best for Boosting Testosterone Levels in Men and Women Overall Additionally, you can also combine testosterone-boosting pills to get better outcomes. However, relying solely on juices to address hormonal issues may not be sufficient, you just need to balance out the diet and workout regime. These altogether potentially enhance wellness by detoxifying the body and improving freshness and rejuvenation for wellness. Studies have shown that cucumber has a great impact in lowering inflammation and supporting hut health. Plus, it is a powerhouse of antioxidants like Vitamin C to reduce or eliminate oxidative stress. Fruits contain vitamins and minerals that help boost test levels in the body. Its nutrient density and potential benefits extend beyond just testosterone support, making it a versatile addition to many dietary regimens. As research in this area continues to evolve, watermelon seed protein remains an intriguing option for those looking to support their hormonal health naturally. The combination of proteins, healthy fats, and minerals in watermelon seeds creates a nutritional synergy that may contribute to overall endocrine health. In the realm of natural testosterone boosters, watermelon seed protein is a relatively new contender. Testosterone (T) is the most important male sex hormone in men and plays key roles in reproductive and sexual functions .Therefore, in this experiment, the forced swimming ability was measured every week to determine how the increase in muscle mass affected the actual exercise performance according to ME and FME administration for 6 weeks (Fig. 3A).These ten foods for erectile dysfunction, included in your daily meals, can help boost confidence, improve circulation, and increase stamina the natural and sustainable way.In summary, at the same dosage, FME administration showed a stronger effect than ME on the reduction in SHBG levels and was deemed to retain a level of bioactive free testosterone that was higher than that in the control group.Before and after each treatment arm, a fasting blood sample was taken for measurement of serum arginine, citrulline, lycopene, glucose, and insulin.Each study was scored based upon its risk of bias being low, with some concerns, or high for each criterion. In addition, saponin was reported to increase the blood testosterone concentration (Salvati et al., 1996). MC contains various bioactive components, on which no study has been conducted directly in relation to male hormones. However, the control group showed similar levels of testosterone even after 6 weeks (225.23 ± 18.21 pg/mL), which indicated that the testosterone levels were steadily maintained in these aging rats without any treatment. In our experiment, the blood testosterone concentration of young rats was 1.86 ± 0.32 ng/mL, which was consistent with the ranges reported in a previous study (Low et al., 2020). Leafy greens are filled with Nitrates that create new blood vessels and improve blood circulation within the body and the penis. Some foods improve blood circulation, hormonal balance, and reproductive health. Foods such as watermelon, garlic, berries, oats, and eggs act as natural erection boosters, improving heart and vascular function. While medication helps, adopting a nutrient-rich diet can naturally boost stamina, hormonal balance, and sexual health. Blackberry is a fruit from the group of dark berries, characterized by containing the fiber called Calcium-D-Glucarate, which helps eliminate excess estrogen, facilitating the increase of testosterone. This type of fat has been linked to an increase in good cholesterol and testosterone. Fruits, due to their high water and fiber content, help in weight loss and maintaining a healthy weight, a key factor for proper hormonal production. Watermelon is a popular fruit consumed around the world for its diverse nutritional and health-promoting qualities. Plants have been used in various regions of the world to treat various medical conditions including male infertility. Conversely, they enhance blood flow and sperm quality in men. They aid in naturally increasing test levels while protecting T-producing cells. Hence, eating food that helps rev-up test levels is also essential. The University of Alabama Institutional Review Board approved the study protocol, and all participants provided written informed consent. Some experts recommend limiting juice consumption, citing its sugar content and lack of fiber that may provide excess kilocalories without concomitant satiety . Age-related decreases in nitric oxide have been directly implicated in declines of vascular endothelial function . Hence, food-first interventions that aim to optimize the vascular function of postmenopausal women before frank CVD ensues are indicated. This is the same body process that Viagra does, but watermelon does it more gently and naturally, without the side effects of medicine. These may help improve blood flow, support heart health, and keep the body hydrated. Watermelon also has lycopene, an antioxidant that supports heart health and blood circulation. To compare the differences between the relative gene expression levels involved in testosterone biosynthesis, RNA was then extracted from the cells using Trizol Reagent (Gibco-BRL). TM3 mouse Leydig cells, which are derived from the testes of immature BALB/c mice and retain many of their in vivo functions, are nontumorigenic testicular cells that were originally characterized based on their morphology, hormone responsiveness, and steroid metabolism (Mather, 1980). Then, testosterone antibody was mixed and incubated in the plate shaker at 500 rpm for 1 h and again for another 1 h in darkness at 37 °C with the substrate solution. Decreased circulating adiponectin levels in obese men may also lead to HPT axis dysfunction or Leydig’s cell resistance to insulin’s actions . An early study showed that Leydig’s cells expressed insulin and type I insulin growth factor (IGF) receptors and both insulin and IGF stimulate T production in primary Leydig’s cell culture . We also verified the relationship between dietary pattern scores and the selected responses (total T, insulin, %TS, and RBC aggregation). Specifically, for this article, we've included juices and nuts that would best increase low testosterone levels in the male body. The Citrullus lanatus extractions of seedsand rind were able to increase serum testosterone levels on healthyanimals treated or restored the levels on animals under oxidativestress induced treatments. A study published in the Journal of Medicinal Food noted that lycopene reduces oxidative stress, leading to healthier testosterone levels (Rao et al., 2018). For example, studies in this review, such as Guo et al. (42), identified a significant increase in lean body mass in addition to a significant increase in testosterone concentrations from 12 wk of supplementation with a fenugreek seed extract. Since cortisol, the body's major stress hormone, is inversely correlated with testosterone concentrations (85), reducing its production may elevate testosterone concentrations. It is well known that inflammation is one of the major causes of testosterone decline in men. They’re rich in antioxidants like beta-carotene, which the body converts into vitamin A. Also, Carrots are a powerhouse of nutrients, boasting antioxidants like beta-carotene and vitamin E, which are fantastic for skin health and overall immunity. A multivariate linear regression analysis was used to analyze the responses that were independently related to the RRR-derived dietary pattern. Therefore, low T levels may cause obesity due to lower muscle energy expenditure. Varlamov et al. suggested that T exerts positive effects on the skeletal muscle mass and local glucose uptake . Watermelon Nutrition Facts Therefore, further studies may be needed to identify the crucial components of MEs affecting the testosterone levels and to investigate the effects of lactic acid bacterial fermentation. Additionally, compared to ME, FME showed significant positive effects on increasing testosterone levels, which suggests that fermentation might increase the content and bioavailability of various bioactive components other than the ones mentioned above. (C) Free serum testosterone levels were significantly increased in the ME40, FME20 and FME40 groups. (A) Total serum testosterone levels were significantly increased in the ME40, FME20 and FME40 groups compared to those in the control group. Serum free Hb (Immunology Consultants Laboratory, Portland, OR, USA), serum hepcidin (DRG International, Springfield, NJ, USA), and sCD163 (R&D Systems, Minneapolis, MN, USA) were analyzed using enzyme-linked immunosorbent assays (ELISAs) following the manufacturer’s instructions. Serum was used to analyze glucose biomarkers, blood lipid biomarkers, liver injury biomarkers, and iron biomarkers. RBC aggregation was defined as the critical shear stress (CSS), which was the minimum amount of force required to disperse RBCs . RBC deformability was defined as the shear stress required for the one-half of the maximal elongation (SS1/2). Whole blood was used to analyze RBC rheology (deformability and aggregation). The heterogeneity of herbal extracts, various dosages used, and differences in sample types (serum, plasma, and saliva samples) make comparing studies and conducting a meta-analysis difficult. In addition, given the existing controversy regarding the relative importance of “bound” and “unbound” testosterone (34), data for testosterone fractions and binding proteins were extracted and presented in the current review to increase the scope of findings. A strength of this systematic review is the inclusion of only randomized controlled trials investigating the effect of a single herb on testosterone concentrations in men. Only 6 out of 32 studies were assessed as having a low risk of bias due to their strong methodological study designs. It's worth noting that most research on testosterone boosters focuses on isolated compounds rather than whole food sources like watermelon seeds.Many fruits, such as bananas and oranges, provide compounds that help reduce cortisol levels, colloquially known as the "stress hormone." This hormone in excess negatively affects testosterone levels.Fruits are among the best testosterone-boosting foods you can add to your diet.Effects of melatonin implants on the reproductive performance and endocrine function of camel (camelus dromedarius) bulls during the non-breeding and subsequent breeding seasons.Therefore, we measured the changes in blood PSA concentrations after 6 weeks of ME and FME administration to verify any negative effect on the prostate that may occur in testosterone replacement therapy (Fig. 1D).Next, the effects of ME and FME on testosterone secretion in vivo were investigated by administrating these extracts to aged rats daily for 6 weeks (Fig. 1A).Thus far, all studies that have found a direct link between ginger or its derived compounds and testosterone were in vivo system studies, and no human studies were conducted in this specific research context. Being a good source of healthy fats and proteins, they help increase testosterone levels. Eating lime helps maintain healthy testosterone levels and promotes overall sexual health. Lemon is rich in vitamin C, an antioxidant that contributes to hormonal balance and helps reduce cortisol, the stress hormone that negatively affects testosterone levels. The high vitamin C content in pineapple supports immune system health and combats stress, which is beneficial for maintaining optimal testosterone levels and a healthy libido. They have a high nutritional level, since they are rich in vitamins, minerals and antioxidants, which increases testosterone levels and improves cardiovascular health. Aside from fruits, there are other testosterone-boosting foods that you might want to consider incorporating into your meals. It's also good to assess your health conditions first before adding these to your diet. They can help improve your reproductive and overall health. For example, in an animal study, Asian ginseng reduced the activity of 5α-reductase, the enzyme responsible for the conversion of testosterone into dihydrotestosterone (DHT) (80). Therefore, herbs with anti-inflammatory and antioxidant properties may have a positive effect on testosterone concentrations. For example, inflammation and oxidative stress have an inverse relationship with testosterone, as demonstrated by several human and animal trials (9, 81–83). Two studies used gelatinized maca (41, 52) and 1 study used a dried maca extract (66). A total of 301 participants were recruited for the studies involving Tribulus terrestris, with ages ranging from 18 to 65 y and sample sizes ranging from 21 to 180 participants. At each visit, percent body fat was also estimated by bioelectrical impedance analysis (BIA) (RJL Systems Inc., Clinton Township, MI). Assessment of serum citrulline and arginine was carried out according to a standardized method for quantitation of amino acids in biological samples . Extraction and quantitation of lycopene was conducted according to a previously described method by Maurer et al, 2014 . Some of the major symptoms of andropause caused by male hormone deficiency are an increase in body fat and a decrease in muscle mass, which lead to muscular weakness and fatigue (Corona et al., 2016). These results indicated that the increase in free testosterone levels depended on the concentration as well as on the fermentation of MEs. To investigate the effect of ME and FME administration on changes in SHBG levels, SHBG concentrations in blood serum were measured between the control group and the experimental group, which received the extracts for 6 weeks (Fig. 1B). Body compositions were divided by the body weight and expressed as the total body fat mass (BFM) (%), skeletal muscle mass (SMM) (%), visceral fat mass (VFM) (%), and subcutaneous fat mass (SFM) (%). This was a cross-sectional study with 125 Taiwanese males aged 20‒64 years. We hypothesized that obesity might affect not only the male sex hormone, T, but also nutrient metabolism (e.g., iron and glucose), and alterations in nutrient metabolism may contribute to the bidirectional relationship between obesity and the male sex hormone, T. However, taken in the context of other studies, it is likely that bioactive compounds in watermelon may be more effective for those with pre-existing comorbidities. Null results for clinical outcomes in this study may reflect the vascular health of our participants at baseline. Results contrast previous studies that reported independent inverse associations with circulating lycopene and PWV 67, 69, atherosclerosis , risk of stroke . Moreover, the thermal processing of pasteurization increases lycopene bioavailability through isomerization 66, 67. Obesity also affects iron metabolism , and iron dysregulation may further contribute to low circulating total T levels 22,23. T is known to affect the body composition, and T supplementation improves the body composition by increasing the lean body mass and decreasing the fat mass 19,20. Although a wealth of observational studies showed an association between low T levels and IR 11,12,13, the direction of the causal relationship remains undefined . The obesity‒hypogonadism relationship is thought to be bidirectional, and changes in adiposity seem to have greater effects on the HPT axis than hypogonadism has on adiposity or body weight 6,15. When talking about male sexual health, one element of special interest is testosterone, the hormone that performs highly relevant functions, affecting a man's appearance and sexual development. Four-week supplementation with 100% watermelon juice did, however, significantly increase fasting serum lycopene. The arginine content of our juice intervention exceeded that of these previous studies, so we hypothesized that supplementation would likewise increase fasting serum levels among our cohort. But here NO is not the way, Citrulline transforms into arginine after consumption, which has effects on blood vessel relaxation akin to those of Viagra. But many times ED is bring on by other sexual malfunctionings like the below ones. Although a small amount of study has been done particularly on watermelon, a few investigations indicate that supplementing with citrulline may be beneficial for ED. Before we move on to that question, let’s spare a few glances at how erections work and find out in what way and to what extent watermelon may help erectile dysfunction. Then look at these seven powerful arguments on why this fruit is good for your sexual health and why you should include it in your diet plan. Certain health conditions can cause abnormally low testosterone. Other effects of low testosterone in men can include brittle bones, hot flashes, enlarged breasts, and even low energy and depression. Testosterone is the hormone that gives men their male characteristics. ED can occur most often when blood flow in the penis is limited or nerves are harmed or with stress or emotional reasons The post explained several benefits of watermelon like reducing blood pressure level,promote weight loss,prevent mineral deficiency among wich one claim was that watermelon can cure impotence The link to the claim is here. The UPMC Men’s Health Center evaluates and treats conditions affecting men’s sexual and reproductive health. Ameliorative effects of oral ginger and/or thyme aqueous extracts on productive and reproductive performance of V-line male rabbits.{A low-CHO diet (32}. An early study by Anderson et al. showed that a high-CHO diet increased circulating total T and SHBG levels, while a high-protein diet had reversed the effect . However, Mikulski et al. showed that both low (35% protein, 64% fat, 1% CHO) and high (4% protein, 1% fat, 95% CHO) CHO meals decreased serum T levels in physically active subjects .|}The University of Alabama Institutional Review Board approved the study protocol, and all participants provided written informed consent.You might still have more questions about testosterone-boosting foods and raising your testosterone levels.On the other hand, an increase in the testosteronelevels was observed in the treated groups.Therefore, further studies may be needed to analyze the active ingredients increased by fermentation.La testosterone It is the predominant sexual hormone in men..It is estimated that 100 grams of raisins contain 3 mg of boron (a mineral that significantly increases testosterone). Two studies used patented extracts, Trib Gold, manufactured by Nerhadou International, standardized to contain up to 45% steroidal saponins (extract source not provided) (39), and Tribestan, manufactured by Sopharma, delivering a minimum of 675 mg furostanol saponins (from overground parts of the herb) (48). There was no statistically-significant difference in SHBG concentrations between the 2 groups (58). Three studies used the Testofen® extract, manufactured by GencorTM (also known as Fenu-FG) (details of extract preparation not provided) (57, 58, 63) and the other 3 studies used the extracts IND9, manufactured by Indus Biotech® (53), Furosap®, manufactured by Chemical Resources (CHERESO) (42), and an extract standardized for Grecunin, manufactured by Indus Biotech® (64) (details of all extract preparations not provided). The final study using Asian ginseng was conducted in 80 infertile men, aged between 25 and 45 y (56). All studies used berry or root extracts of Asian ginseng (Panax ginseng), with the root reported as Korean red ginseng, a processed form (67). If your testosterone has dipped because of these factors, the best way to boost it is with diet and lifestyle changes. But if you are overweight, have insulin resistance, are under lots of stress, or aren’t sleeping well, you might have worse symptoms. Much of the time, men in their 40s and 50 notice symptoms of lower testosterone — which may be a natural decline due to aging. If necessary, your doctor can order further testing to identify the cause of low testosterone and recommend treatments. If you feel like your testosterone might be abnormally low, you should talk to your doctor. Lanatusrind was able to increase testosterone above the levels observed atthe control group and also increased significantly the testosteronelevels of the lead acetate group, confirming the results showed byGodspower et al., . On the other hand, an increase in the testosteronelevels was observed in the treated groups. This study shows a significantly impact on the valuesof serum testosterone when the animals were exposed to a highoxidative situation. The added benefit is that it comes in a whole food form, potentially offering synergistic effects from other nutrients present in the seeds.RBC aggregation was defined as the critical shear stress (CSS), which was the minimum amount of force required to disperse RBCs .19 Although not observed in this study, recent research suggests that sustained increases in circulating lycopene attenuate neuroinflammation and oxidative stress resulting in enhanced cognitive performance as evidenced by functional MRI.Accumulating evidence suggests a tight link between the nutritional status and male reproductive function, particularly the effects of calories or macronutrients on male sex hormone total T levels .Amy Ellis, PhD, RD and Kristi Crowe-White, PhD, RD are Co-Principal Investigators who contributed equally to the design and management of this study. These are an excellent plant source of zinc and vitamin D, which help to increase hormone levels. They also contain vitamins and minerals (zinc and magnesium), which are important for healthy hormone production. Although fruits are essential for increasing testosterone, they do not replace other foods that are equally important for hormone production. While quick fixes will always exist, the right combination of vitamins, antioxidants, and other heart-healthy nutrients can help you address the root of the problem. Including these foods that improve erection in your diet helps sustain your overall health and vitality. Maintaining good circulation and balanced hormones is also helped by the avoidance of excess alcohol, tobacco, and junk food. Moreover, the protein in eggs helps to rebuild tissues and sustain energy during physical and sexual activities. One randomized, double-blind, placebo-controlled study was conducted examining the effects of a musali root extract (water extract of dried root tubers) on testosterone concentrations (59). One randomized, double-blind, placebo-controlled study was conducted examining the effects of a rhodiola extract (standardized to 3% rosavins) on testosterone concentrations (46). There were no statistically-significant increases in testosterone concentrations after 12 wk of supplementation in any of the trials. Three randomized, double-blind, placebo-controlled studies (41, 52, 66) examined the effects of maca on testosterone concentrations. The inclusion of the testosterone fractions and binding proteins were deemed important since only ∼2% is “free” testosterone, with the remaining testosterone “bound” to proteins (predominantly SHBG, ∼40–45%) (31–33) and controversy existing regarding the relative importance of “bound” and “unbound” testosterone (34). Risk of bias of the included studies was assessed using the Cochrane Collaboration's tool for assessing the risk of bias in randomized trials (30). Each study was scored based upon its risk of bias being low, with some concerns, or high for each criterion. The reference lists of relevant papers were also examined to locate additional studies that were not identified by the initial database search. 6 Despite largely null findings reported herein, 100% watermelon juice is indeed an effective vehicle for bolstering serum lycopene.To investigate the effect of ME and FME administration on changes in SHBG levels, SHBG concentrations in blood serum were measured between the control group and the experimental group, which received the extracts for 6 weeks (Fig. 1B).Pre and post each intervention arm, fasting blood and urine samples were collected, and cognitive tests were administered by one trained study personnel to assess various neurocognitive domains.Semen quality, testosterone, seminal plasma biochemical and antioxidant profiles of rabbit bucks fed diets sup-plemented with different concentrations of soybean lecithin.In support of the findings of this review, a recent meta-analysis of clinical trials on fenugreek seed extract supplementation reported a significant increase in testosterone concentrations (68).This makes them a valuable addition to plant-based diets and potentially beneficial for overall hormonal health.You’ll still gain the same nutritional benefits found inside the seedless watermelon flesh as you would with a regular seeded watermelon. Four studies (39, 48, 54, 61) examined the effects of Tribulus terrestris on testosterone concentrations. The researchers examined testosterone concentrations in 60 stressed, healthy men and women with a mean age of 41 y. Four studies were conducted examining the effects of ashwagandha on testosterone concentrations (35, 50, 51, 62). Since the beginning of 1991, various in vivo and basic research studies have found a link between ginger and testosterone. Insufficient levels of testosterone in men are linked with a wide range of disorders/diseases such as infertility , diabetes , osteoporosis , and bone loss . Since 1991, various in-vivo, as well as basic research studies, have discovered a link between ginger (Zingiber officinale) and testosterone. Desjardins C. Endocrine regulation of reproductive development and function in the male. Resveratrol attenuates malathion induced damage in some reproductive parameters by decreasing oxidative stress and lipid peroxidation in male rats. Therefore, we directly measured the concentration of free testosterone in blood serum as an expression of bioactivity after 6 weeks of administration. Testosterone that is not combined with SHBG (free testosterone) actually functions as an active hormone (Ring et al., 2017). The study found that the testosterone level decreased in the EMR-treated group but increased and recovered to the level of the control group when the EMR-treated group was supplied gallic acid. Catechins (catechin and epicatechin) were reported to increase the plasma testosterone level in vivo in male rats by acting directly on rat Leydig cells through increasing the effect of cAMP (Yu et al., 2010). Comparative effects of zinc oxide, zinc oxide nanoparticle and zinc-methionine on hatchability and reproductive variables in male Japanese quail. Min Y, Sun T, Niu Z, Liu F. Vitamin c and vitamin e supplementation alleviates oxidative stress induced by dexamethasone and improves fertility of breeder roosters. Radhakrishnakartha H, Appu AP, Madambath I. Reversal of alcohol induced testicular hyperlipidemia by supplementation of ascorbic acid and its comparison with abstention in male guinea pigs. Modulation of age-related biochemical changes and oxidative stress by vitamin c and glutathione supplementation in old rats. Effect of selenium supplementation on attainment of puberty in Saanen male goat kids. Healthy blood vessels are essential for the proper flow of blood during sexual arousal, and lycopene may help promote better erectile health. But does lycopene play a role in male sexual health? Dehydration can negatively impact various bodily functions, including circulation and energy levels—both of which are crucial for sexual health. While the study involved citrulline supplements, watermelon’s natural citrulline content suggests it could have similar effects when consumed as part of a healthy diet. However, it’s important to note that simply eating watermelon won’t single-handedly fix gut health issues. When your gut thrives, your body can absorb necessary nutrients and regulate hormones more effectively. Watermelon contains dietary fiber, which is essential for gut microbiome health. This is crucial because testosterone synthesis requires a well-functioning circulatory system. At screening, a list of lycopene-containing foods was provided, and participants were instructed to limit these foods to two or fewer servings per day for the duration of the study. Three members of the study staff who were unblinded packaged juice and placebo to provide two 360mL servings per day. In a double-blind crossover design, participants were randomized to supplement their diets twice daily for four weeks with either 360 mL of 100% watermelon juice or an isocaloric placebo that was matched for sugar content. In a double-blind crossover design , participants were randomized to two 360 mL servings of 100% watermelon juice per day or an isocaloric placebo for four weeks each with a two-week washout period in between. This enhanced blood flow to critical locations during intercourse can wrap up numerous sexual dysfunctions. Maintaining the optimal level of testosterone in the male body is essential. You might still have more questions about testosterone-boosting foods and raising your testosterone levels. Almonds and walnuts, for example, increase sex hormone-binding globulin (SHBG), lowering test production. Watermelon is packed with several vitamins and nutrients that contribute to overall health. There are as many ways to consume watermelon as there are stars in the sky. To be precise, the compound called lycopene in the melons prevents sperm from congregating and failing to germinate into an egg. Watermelon may facilitate longer-lasting relationships, increase enjoyment from the encounter, and improve sex experiences in general. Summer melon may hold the key to your improved blood circulation if you’re searching for a tasty and organic solution. Of all sweets, dark chocolate is the best food for erectile dysfunction as it improves your health while satisfying your sweet tooth. Additionally, it increases brain levels of serotonin and dopamine, which boost mood, and lower anxiety and increase libido. A healthy heart ensures efficient blood flow to the penile region, which helps to maintain hard erections naturally.
