This will be a reference for requirements and testing for subjected devices. On January 10, 2025, the Ministry of Communication and Informatics (KOMINFO) released Regulation of the Minister of Communication and Digital Number 1 of 2025 concerning the Organization and Work Procedures of the Ministry of Communication and Digital. These include cardiovascular disease, obesity, diabetes, and respiratory disorders, all of which can impact hormonal balance and contribute to lower testosterone levels. Smokers may experience an earlier onset of age-related hormonal changes, leading to further reductions in testosterone levels compared to non-smokers. Adrenaline is involved in the body's fight-or-flight response and can transiently elevated testosterone levels as part of this physiological reaction. These effects are typically temporary and can vary depending on individual factors such as smoking history, frequency of smoking, and overall health status. So while more research needs to be done in this area, vaping does appear to impact your hormones and testosterone levels.

On January 6, 2025, the Bureau of Standards, Metrology and Inspection (BSMI), Ministry of Economic Affairs (MOEA) published the revised regulation for changing the Commodity Classification Code or Reference C.C.C. Code the first 6 digits are the same as HS Code for wireless chargers, which will be effective from January 24, 2025. On February 11, 2025, the Moroccan Institute of Standardization (IMANOR) released a public inquiry no. It is suggested that enterprises get fully prepared during transition period and implement the two standards at the latest by January 1, 2026. There is a lack of data about the germline epigenetic effects of e-cigarettes and HNB devices, leaving a significant knowledge gap. It is known that the environment, including lifestyle habits such as smoking, could affect the epigenetic response of the individual, and the most known epigenetic modification is DNA methylation, which effectively “silences” gene transcription. Furthermore, tobacco smoke has been shown to decrease nuclear protamine levels and protamination (created with BioRender.com). This increase in ROS levels can also trigger apoptosis by raising the levels of pro-apoptotic cytokines, which further contributes to sperm DNA damage and impaired male fertility. However, chronic use leads to sustained decreases in testosterone, impacting various aspects of men’s health. Prioritizing a balanced lifestyle will support healthier hormone levels and improve your quality of life. The relationship between nicotine and testosterone is influenced by various factors like dosage and individual biology. On May 22, 2025, the Communications Regulatory Commission (CRC) issued Decision No.183, adopting a draft to amend and supplement the rules for free use of the radio spectrum. On April 24, 2025, the Telecommunications Regulatory Commission (TRC) launched a public consultation on its 5G spectrum strategy.

Czech Republic CTU Issues General Authorization for the Use of Radio Frequencies for the Operation of Short-Range Devices This also adds conditions on QR code requirements and provisions on medical applications. On May 22, 2025, the Ministry of Transport and Telecommunications (MTT) released Resolution 737 Exempt, "Modifies Resolution 1985 Exempt of 2017, of the Undersecretary of Telecommunications that Establishes Technical Standards for Short Range Equipment". As such, men who smoke cigarettes or partake in other forms of nicotine consumption should be aware of these possible long-term consequences before making any decisions regarding their own health and wellbeing. Nicotine, an addictive chemical in tobacco products and e-cigarettes, has been linked with various health issues, including cancer and heart disease. A growing body of evidence suggests that nicotine use can have long-term side effects. While further research is needed into the long-term effects of nicotine consumption, these initial findings provide an exciting insight into how small amounts of this chemical might affect both mental and physical well-being.

Research on the effects of nicotine replacement methods on testosterone levels is limited. A study published in the journal PLOS One found that men who quit smoking experienced an increase in testosterone levels after six months of abstinence. A study published in the Journal of Sexual Medicine found that increased pack-years of smoking were linked to a higher likelihood of having low testosterone levels. A clinical trial conducted to evaluate the effect of cigarette smoking on testosterone levels in healthy men found that smokers had similar levels of free testosterone compared to non-smokers. This measure aims to protect consumers by informing them of essential information for purchasing and using these products. This standard was announced on December 27, 2024, and took effect on March 28, 2025. This standard is referenced in VC Compulsory specification for electric motor-operated hand-held tools, transportable tools and lawn and garden machinery. Therefore, certificates mentioning this standard will be updated considering the 2-year transition period. This action plan addresses the safety hazards of electric bicycles and supports the supply of compliant electric bicycles with CCC certification in large quantities to the market. The popularity of nicotine pouches has seen a global surge, particularly due to an increase in health consciousness and a growing understanding of the detrimental health consequences of smoking. Low testosterone levels can lead to fatigue, mood changes, reduced libido, difficulty concentrating, and even sleep disturbances. Plus, it’s not just about testosterone; smoking affects various aspects of our health, from respiratory to cardiovascular. Moreover, reduced testosterone levels can lead to an accumulation of visceral fat, which surrounds our internal organs. Balance My Hormones helps men and women restore their hormones to optimal levels through bespoke TRT and HRT treatment plans. Low testosterone, also called male hypogonadism, has various causes. All across the world, millions of men have found a solution to low testosterone through a treatment called testosterone replacement therapy (TRT). Mike has over 25 years of experience in the healthcare sector, much of that working with people who have hormone imbalances. Interestingly, another trial reported that chewing nicotine gum leads to a significant decrease in salivary testosterone. Unfortunately, there are only a few studies that have delved into the potential effects of chewing tobacco on testosterone. Chewing tobacco, also known as smokeless tobacco or snuff, is another form of nicotine exposure that may affect hormonal levels in men. The evidence is even less conclusive on whether smoking marijuana may lower testosterone, as the effect appears to depend on several factors such as type of cannabis, THC and CBD ratio, etc. For example, some trials reported that smoking depletes overall zinc levels, which are otherwise important for normal testicular function. Prolonged activation of the nAChR leads to desensitization and upregulation of nAChR density 47, 48 and nicotine is more likely to induce these changes than the endogenous ligand acetylcholine (ACh). It will provide an overview of recent advances in understanding nicotine’s effects on cognitive function, a discussion of the role of cognitive function in vulnerability to TUD, followed by an overview of the neurobiological mechanisms underlying the cognitive effects of nicotine. Of necessity, this review will be highly selective given the vast body of work on the cognitive effects of nicotine. Although some controversy remains regarding nicotine’s effect on specific cognitive functions, and on individual differences in nicotine’s cognitive effects, the preponderance of evidence from animal and human studies has established cognitive-enhancing effects as a clinically relevant dimension of nicotine psychopharmacology. Nicotine’s cognitive effects in the prefrontal cortex provide negative reinforcement and nicotine’s effects on reward circuitry in the nucleus accumbens provide positive reinforcement. IECEE Adds New Test Report Forms (TRFs) on Week 48 (2024-W48)On November 29, 2024, new TRFs were published and added to the IECEE website. Saudi Arabia SASO Publishes List of Updated Version Standards of International Electrotechnical Commission (IEC) for Electrical and Electronic SectorThis update is in reference to previous news, which mainly focuses on new mandatory date which will be on January 2026 instead of April 23, 2025.Official source USA EPA Publishes Reminder for the Sunset of Energy Star Specifications for Lamps and LuminairesOn December 2, 2024, the US Environmental Protection Agency (EPA) published a reminder regarding the sunset of the ENERGY STAR specification for lamps (aka light bulbs) and luminaires (aka light fixtures). Testosterone is essential for everyone, affecting not just physical traits like muscle growth, bone strength, and overall energy, but also your mental and emotional well-being. Smoking is a dangerous habit, yet it’s tough to kick due to nicotine’s addictive nature. The information should not be considered complete and should not be used in place of a visit, phone or telemedicine call, consultation or advice of your physician or other healthcare provider. Discuss this information with your own physician or healthcare provider to determine what is right for you. However, other studies have failed to prove an improvement in sports performances after nicotine intake 44,47. Some studies have supported the notion that nicotine could alter sports performances 8,46. Although nicotine could cause vasoconstriction to affect muscular O2 uptake, the intensity of the muscle strength test was not sufficient to cause an oxygen delivery problem. For those seeking to understand the connection between smoking and their hormonal health, it is crucial to consider cessation as a step toward recovery and improved testosterone levels. Quitting smoking can have various positive effects on testosterone levels. Understanding the effects of quitting smoking is essential for individuals concerned about their testosterone levels. Notably, the cessation of nicotine exposure was found to alleviate its negative effects on testosterone levels. The chemical can influence hormone synthesis and control directly and indirectly, affecting general health and well-being. Nicotine is released into the circulation via the skin (patches), oral mucous membranes (gum and lozenges), or respiratory system (inhalers and nasal sprays). Vaping is a newer practice that involves heating liquid nicotine in an electronic device (e-cigarette) and inhaling the resulting vapor. An imbalance, whether too low or too high, causes multiple health problems, including decreased libido, infertility, bone density loss, muscle weakness, and mood swings. The research on smoking and testosterone appears to show conflicting results. But over the years, research has made it clear that tobacco smoke (and nicotine) can harm testicular function and affect testosterone production, reducing fertility. They might assume that smoking only affects lung health or raises their risk of cancer. Quitting smoking may mitigate many health dangers, including male infertility. On Aug. 12, 2025, the California Energy Commission (CEC) published an amendment to the California Energy Commission to align California’s appliance standards with federal regulations. This standard forms the foundation of the IEC series and establishes the fundamental safety requirements for electrical installations to protect people, livestock, and property. It is proposed to include rechargeable handheld electric tools in the scope of regulated electrical equipment that requires mandatory BSMI certification and to update the relevant inspection standards.

Is vaping safer than smoking in terms of testosterone levels?

Let’s bring it all together next with a no-BS verdict on ZYN and your testosterone health. Using nicotine while your body’s still leveling up can throw off your natural testosterone rhythm. Physiol Res, 2017 showed that older nicotine users had 30 percent lower testosterone than non-users of the same age. So it shifts energy away from testosterone and into stress mode. Australia and New Zealand Publish Multiple Electrical Safety Standards for Household and Similar AppliancesOn November 29, 2024, the Standards Australia and New Zealand published multiple electrical safety standards for household appliances. The standard outlines specific safety and performance requirements for medical electrical equipment used in haemodialysis, haemodiafiltration, and haemofiltration.

People take it mainly through cigarette smoking, vaping, or nicotine gums and patches. Now you have the answer to “does nicotine increase testosterone”? Zyn, a tobacco-free nicotine pouch, does not increase testosterone. Nicotine is a powerful, addictive chemical found in all tobacco products and the compound responsible for making smoking so relaxing and pleasurable.

In recent years, researchers (and pharmaceutical companies) have focused on the effects of testosterone deficiency, especially among men. Blood levels of testosterone vary dramatically over time and even during the course of a day. What's more, testosterone plays other important roles in health and disease that may surprise you. If you’ve been wondering how smoking might be affecting your reproductive health, Craft Men's Clinic is here to guide you. Quitting smoking, whether cigars or vaping, is one of the best steps you can take for your health.

In addition to ACh and DA, other neurotransmitters participating in the cognitive-enhancing effects of nicotine in both the hippocampus and the prefrontal cortex 21, 97, 98 include glutamate, norepinephrine, serotonin, and GABA. The activation of nAChRs on the VTA DA cell bodies, and presynaptic terminals, in the nucleus accumbens and the prefrontal cortex , contribute to the rewarding and cognitive-enhancing effects of nicotine, respectively (Fig. 1). However, the finding that in this attentional task, nicotine treatment also reduced performance in wild-type, but not in the α5 knockouts, demonstrates the complex manifestations of nicotine’s effects on cognition and the limitations of preclinical knock-out models . Data from preclinical models suggest that the α2, α5, α3, and β4 subunits may also play a role in the cognitive effects of nicotine . The distribution of the β2 subunit is enriched in the basal ganglia, thalamus, and hippocampus, and accumulating evidence supports a primary role of the β2 subunit in the cognitive effects of nicotine . It’s natural to wonder if ceasing nicotine use might reverse its potentially negative effects on the male body. Therefore, nicotine use has the potential to impact men’s sexual health significantly. Although nicotine might cause a small boost in testosterone, it can negatively impact men’s bodies in several other ways.

• There is a significant association between these chronic conditions and lowered testosterone, which can impact male fertility.
• You want to be behind the wheel of a healthy, fine-tuned sex machine.
• This took effect on its publication date in the Official Gazette which was January 29, 2025.
• This is true even if you are getting extra testosterone through TRT.
• This establishes some mandatory rules like security standards of products that can directly or indirectly connect to the internet.
• That’s because while testosterone plays a big role in pumping up sexual desire, it is far from the only thing that drives libido, which means that if yours is lacking, low testosterone may not be your issue.
• It was the Buddha who said, wisely, “To keep the body in good health is a duty, otherwise we shall not be able to keep our mind strong and clear.” I’m not going to give you a set time you need to eat, or a set amount you need to eat.
• Total and free testosterone levels increased significantly with the increasing number of cigarettes smoked daily .

In this study, we aimed to evaluate the effects of smoking cessation on the sexual functions of men aged 30 to 60 years. There are several hypotheses on the physiopathological effects of long-term smoking on sexual dysfunction. Reducing smoking, engaging in regular exercise, adopting a healthy diet, losing excess weight, controlling diabetes, and making positive lifestyle changes have proven to reduce the risk of ED and metabolic syndrome ( 7 ). The patients filled the International Index of Erectile Function (IIEF) form before the cessation and six months after cessation of smoking. We aimed to evaluate the effects of smoking cessation on the sexual functions in men aged 30 to 60 years. Most acute information is from nicotine administration studies whereas chronic information is predominantly from studies on cigarette smokers. Decreases in skin temperatures, arousal and relaxation are also noted following nicotine administration . Activation of nAChRs in the adrenal medulla leads to increased catecholamine levels with corresponding cardiovascular and metabolic responses. In the brain, nicotine acts by binding to and activating the nicotinic acetylcholine receptors (nAChRs), members of a superfamily of transmembrane ligand-gated ion-channel proteins , found in both the CNS, peripheral nervous system (PNS) as well as in some peripheral tissues . In humans, when nicotine is inhaled, it rapidly enters the blood stream, crosses the blood–brain barrier and reaches the central nervous system (CNS) where it acts as a stimulant 100,101. Early morning levels of total, free and bioavailable testosterone, 17beta-oestradiol, SHBG and cotinine were determined and compared between the two groups. We attempted to determine whether smoking affects the level of bioavailable testosterone. The effect of smoking on androgen levels is important given the recent interest in the link between low levels of androgens and the development of cardiovascular disease. In addition, what may seem like a symptom of testosterone excess (see below) may actually be unrelated to this hormone. Having too much naturally-occurring testosterone is not a common problem among men. Testosterone levels are too carefully controlled by the brain for that to occur. Endurance-based exercises, like cardio, can potentially reduce testosterone. “You should exercise to keep your endurance, lean muscle, and low body fat, which will, in turn, keep you healthy,” El-Zawahry says. Exercise affects testosterone in other ways, too, says Brian McNeil, M.D., chief of urology at SUNY Downstate Health Sciences University. A small 2016 study found that obese and overweight men saw a boost in their T levels when they increased their physical activity, more so than when they solely restricted calories. Body composition and fitness level factor into how exercise affects your testosterone, too. Hyperprolactinemia impairs male gonadal functions by acting at various levels, possibly by decreasing GnRH pulse generator activity and/or by decreasing LH and FSH secretion, and might be inhibiting testosterone secretion at the level of Leydig cells as well. The recovery groups showed comparable values with the control indicating that the effect of nicotine on testosterone can be ameliorated by nicotine cessation. The protocol used for the hormone was according to the method described for the kit (Immunometrics Limited, UK) and meet the World Health Organization (WHO) standards in research programme for human reproduction. The Vmax was not affected significantly (p greater than 0.60) and Km increased with increasing concentrations of nicotine and cotinine (p less than 0.05). When microsomal fractions were incubated for 1 hour with and without nicotine (0-50 microM) and cotinine (0-100 microM), enzyme activity of HSD was significantly suppressed (p less than 0.001). The activity of delta 4 steroid 5 alpha-reductase, which converts testosterone to 5 alpha-dihydrotestosterone (DHT) was measured in isolated dog prostate nuclei using testosterone (0-200 nM) as substrate and NADPH as cofactor. We have recently observed that cigarette smoking affects plasma androgen concentrations. Research shows that men who smoke are more likely to experience a faster decline in testosterone as they grow older. Note that the baseline levels of venous plasma nicotine are very low, indicating that the subject volunteer smokers were indeed tobacco abstinent overnight. It is obvious that smoking denicotinized cigarettes produced a minor delta venous plasma nicotine increase of only 0.88 ng/ml, whereas smoking average nicotine cigarettes produced a 12.9 ng/ml increase. Linear regression was conducted to establish the relationships between nicotine cortisol and prolactin levels. This study was part of a larger ongoing project involving tobacco smoking effects on human dopamine D2 and mu-opioid brain receptors using positron emission tomography (PET). The participants’ testosterone levels were normalized thanks to the therapy. This can also lead to improvements in sperm quality and testosterone levels over the long term. These, along with other chronic conditions, are known to decrease testosterone levels. However, their testosterone levels were surprisingly 14% higher on average. The Journal of Urology points out that normal serum testosterone levels usually range from 300–1,000 ng/dL. The aim of this regulation is to prescribe the technical eco-design requirements for the placing on the market of smartphones, mobile phones, cordless phones, and tablets ensuring these devices meet specific standards for energy efficiency and environmental impact. This draft law is a technical adaptation, streamlining German chemicals regulation by updating references to EU law, removing obsolete or redundant national rules, and enhancing environmental and public health safeguards in line with international and European goals. This standard deals with the safety requirements of electrical equipment for measurement, control and laboratory use having testing or measuring circuits.

Understanding the relationship between smoking and testosterone levels is an essential step in comprehending the potential effects of smoking on hormonal health. Understanding the impact of smoking on testosterone levels is important for individuals looking to assess the potential effects of smoking on their hormonal health. Quitting smoking not only benefits testosterone levels but also has numerous positive effects on overall health. While nicotine may cause a brief uptick in testosterone levels, the long-term effects of smoking are overwhelmingly negative. Although smoking may increase total and free testosterone levels temporarily, it can have detrimental effects on overall reproductive health, which remains a significant concern for many individuals.

CalRecycle will also hold a hybrid public hearing on the draft regulation on Oct. 7, 2025, at 10 a.m. These changes aim to enhance safety management for energy storage systems with a capacity of 20 kW or more and clarify inspection procedures for high-voltage electrical installations. It requires compliance with technical, safety, and cybersecurity standards, promotes performance monitoring, and independent verification. Studies citing tobacco smoking nicotine exposure were either excluded or addressed cautiously as appropriate. In order to analyze any potential pathological roles of nicotine, there is a need to consider it in both isolation and within the new landscape of emerging tobacco heating products and electronic nicotine delivery systems (ENDS). Newly developed tobacco and nicotine-containing products such as e-cigarettes are being widely accepted by consumers. In addition, cigarette smoking may reduce the efficacy of estradiol therapy in increasing bone mass . Calcium absorption and vitamin D levels are lower in smokers , with variable reports on PTH levels 47,48. The association between smoking and osteoporosis is well established with increased hip fractures seen in smokers . These results, in both rats and humans, suggest that smoking may be related to increased contractile sensitivity of preterm myometrium in response to OT, which leads to increased risk of preterm delivery in women who smoke during pregnancy . This aims to update the specific standards for boxes and enclosures for electrical accessories, conduit systems buried underground, and low-voltage switchgear and controlgear, aligning with the latest European harmonized standards. On February 7, 2025, the Saudi Standards, Metrology and Quality Organization (SASO) published a list of adopted Saudi Standards Specifications from the International Electrotechnical Commission (IEC) for the scales, weights, electrical and electronic sectors. This standard deals with the safety requirements for hand fed, shredders/chippers. This standard outlines the basic safety and essential performance of X-ray-based image-guided radiotherapy equipment for use with electron accelerators, light ion beam therapy equipment and radionuclide beam therapy equipment. Given these opposing views, we stress the importance of further investigation into how nicotine and smoking affect testosterone. This balancing act ensures that testosterone levels stay within an optimal range, maintaining our physiological stability. If our testosterone levels rise too high or dip too low, the body adjusts its production accordingly through a mechanism termed “negative feedback”. Our bodies regulate testosterone levels through a complex system known as the hypothalamic-pituitary-gonadal (HPG) axis. Our sexual function and overall well-being are closely tied to adequate testosterone levels. This update amends the current PFAS law by excluding from the prohibition products containing intentionally added PFAS only in their electronic components or internal components.

Department of Energy (DOE) published a document delaying the effective date of a recently published final rule amending the test procedures for compressors. The rule amending 10 Code of Federal Regulation (CFR) part 431 was published on the Federal Registrar (FR) at 90 FR 7464 on January 21, 2025, and will not go into effect until May 20, 2025. The group discussed energy efficiency criteria, label design, implementation plans and the labeling schedule. The absence of a decrement in self-reported sexual arousal in response to nicotine administration supports the notion that nicotine attenuates genital arousal directly via physiological mechanisms, rather than impacting cognitive processes. This indicates that the decrease in physiological sexual arousal in response to nicotine administration was not a result of negative feedback from cognitive appraisal of the erotic films. Specifically, nicotine instigates cardiovascular constriction by direct stimulation of epinephrine and norepinephrine release from peripheral sympathetic nerve endings . These findings suggest that the cardiovascular consequences of nicotine were in effect during assessment of sexual arousal. In this review we critically evaluate the literature concerning the impact of nicotine as well as tobacco use on several parameters of the endocrine system and on glucose and lipid homeostasis. Tobacco or nicotine use influences the endocrine system, with important clinical implications. Always consult a licensed healthcare professional before starting, changing, or discontinuing any medical treatment. Some studies indicate that nicotine can increase testosterone levels, while others find a decrease in testosterone with nicotine use. The landscape of research on the impact of nicotine on testosterone levels has shown conflicting results. Here, we'll delve into the impact of nicotine gum and e-cigarettes on testosterone levels. In summary, while the relationship between smoking and testosterone levels is complex and multifactorial, there is a consistent association between smoking and increased levels of testosterone. There is significant clinical evidence supporting that individuals who begin smoking during adolescence are more likely to have trouble quitting than those who start as adults (Breslau and Peterson, 1996; Cengelli et al., 2012; Chen and Millar, 1998; DiFranza and Lew, 1995; Kandel and Chen, 2000; Khuder et al., 1999). The increased reward induced by nicotine may lead to subsequent abuse of other drugs, including nicotine itself, alcohol, cocaine, methamphetamine, and fentanyl (Alajaji et al., 2016; Cardenas et al., 2021; Cole et al., 2019; Collins and Izenwasser, 2004; Collins et al., 2004; Dao et al., 2011; Linker et al., 2020; McQuown et al., 2009, 2007; Pipkin et al., 2014; Reed and Izenwasser, 2017; Thomas et al., 2018). Disruption of the cholinergic system during this period via early postnatal nicotine exposure impairs development of the cortex and hippocampus, and produces permanent changes in cortical circuitry that result in deficiencies in somatosensory, auditory and cognitive processing (Aramakis et al., 2000; Heath et al., 2010; Hsieh et al., 2002; Huang et al., 2007; Liang et al., 2006). The first twelve days of rodent development are comparable to the third trimester of human gestation (Quinn, 2005), so nicotine exposure during the early postnatal period in rodents is also studied for a comprehensive understanding of human prenatal nicotine exposure. However, because rodents are born at an earlier stage of brain maturation than humans, prenatal nicotine exposure in rats or mice only translates to exposure during the first two trimesters of human gestation (Bayer et al., 1993; Quinn, 2005). Nicotine can affect hormone levels, but its impact varies based on individual habits. These studies show a mixed view on nicotine’s impact. Understanding these research findings is crucial for anyone interested in health and wellness. Others indicate it could have no effect or even boost testosterone. This research underscores the value of positive psy-chology frameworks in fostering healthier and more adaptive academic environments in thedigital age. With the integration of evidence-based inter-ventions, the psychoeducation program seeks to mitigate the adverse effects of excessivedigital engagement while enhancing students' capabilities to thrive in an increasingly digitaleducational environment. The program, which is based on the principles of positive psychology, is intendedto enhance psychological well-being, resilience, and adaptability by encouraging healthierhabits and a balanced use of digital technology. On Aug. 25, 2025, the Government Legal Service (RDR) of Liechtenstein published an amendment to the Cyber Security Act (CSG) in the National Law Gazette (LGBl. 2025 No. 409). On Aug. 25, 2025, the Computer Incident Response Team (Sz-CIRT) of Eswatini Communications Commission (ESCCOM) released SZ NCS 2025, “the National Cybersecurity Strategy 2020 – 2025.” This describes a coherent national approach for protecting Eswatini’s data, systems and networks from cyber risks. On Sept. 17, 2025, the Ministry of Health, Labor and Welfare (MHLW), the Ministry of Economy, Trade and Industry (METI), and the Ministry of Environment (MoE) published the draft Revision of the Order for Enforcement of the Act on the Regulation of Manufacture and Evaluation of Chemical Substances. This proposed regulation aims to reduce human health risks from 2,4-DNT in articles available in the EU market by restricting the presence and use outside controlled industrial contexts, especially in consumer and professional settings.

The Psychological Impact of ED in the Ozempic Era

The authors conclude that unlike conventional cigarettes, nicotine is the sole ingredient in e-cigarettes responsible for inducing cardiovascular response. Plasma nicotine was only significantly increased after four puffing bouts; heart rate was elevated after the first and second but returned to baseline by the third puffing bout. Five minutes after six puffing bouts of an e-cigarette, plasma nicotine increased from a baseline of 2.2 ng/ml to 7.4 ng/ml. In addition to this mechanism, stimulation of nAchR expressed in autonomic nervous system ganglia may also influence cardiovascular regulation (Liet al., 2009). This document specifies requirements for the maximum amount, and in some cases, the maximum concentration of certain substances and mixtures used in experimental sets for chemistry and related activities. On May 31, 2025, the European Chemicals Agency (ECHA) released the 3rd edition of the Compendium of Analytical Methods Recommended for the verification of compliance of REACH Annex XVII restrictions. Additional changes include adding some specific requirements and test methods (i.e., requirements for diameter of ropes, requirements for hand-gripping and hand-grasping, requirements for crush and shear points, requirements for handrails on the starting section of slides, requirements for see-saws). This new version of the standard includes a new definition for activity toys which includes paddling pools. This document specifies requirements and test methods for activity toys for indoor and outdoor domestic family use intended for children under 14 years to play on or in. Advertisements from drug companies can make it seem like all your problems can be solved by taking testosterone. If you’ve been taking supplemental testosterone for a long time, it can be a lengthy process to wean off of it and restore your body’s own testosterone production. If you supplement with testosterone, your body senses that there’s plenty and starts downregulating your own production. On July 22, 2025, the General Administration of Customs of the People's Republic of China (GACC) issued a draft revision on the Measures for the Administration of Imported Wood Packaging Material. On July 22, 2025, the Saudi Standards, Metrology and Quality Organization (SASO) drafted an update to the technical regulation for motorcycles. This standard provides a general overview and principles for determining the sound power levels of fans.

Age-Related Effects of Smoking on Testosterone

If you're looking to maintain healthy testosterone levels, smoking is definitely something you want to avoid. While preclinical studies have provided insights into the detrimental effects of nicotine on sperm quality and testosterone levels, translating these findings to clinical practice is essential. In this article we will find out the truth and how nicotine and smoking affect testosterone levels in men. The good news is that smoking cessation can have a positive impact on testosterone levels and overall health. Nicotine’s effects on the body, particularly through cigarette smoking and vaping, are a topic of ongoing interest, especially its potential relationship with testosterone levels. It states however "Nicotine is, however, responsible for getting smokers addicted to cigarette smoking in the first place - usually while they are children or young adults and their brains are still developing - and keeping them addicted long-term". I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard. Further studies are needed to determine whether nicotine is detrimental to fertility in humans. Experimental molecular biology can demonstrate possible cancer progression pathways that may be brought about in response to nicotine, but these have not been investigated in cases of human cancer. The difference was approximately 1.53 nmol/L, suggesting that initial exposure to nicotine could enhance testosterone levels . The relationship between smoking and testosterone levels is multifaceted. Research also indicates that smoking affects testosterone levels in postmenopausal women.

• ” is because right after your first puff of smoke, your body actually has a temporary boost of testosterone.
• However, chronic nicotine consumption is linked to lower testosterone production over time, leading to potential hormonal imbalances.
• Let’s take a closer look at the link between nicotine and testosterone.
• Nicotine and some other components of the cigarette smoke cause various endocrine imbalances, and have negative effects on pituitary, thyroid, adrenal, testicular and ovarian functions.
• Some studies claim a short-term boost in testosterone levels from smoking, which is largely attributed to nicotine’s effect on adrenal glands.
• Third, the current study counter-balanced the assessment starting point (i.e., follicular versus luteal phase) to ensure that any cycle effects observed were not due to assessment fatigue.
• This could mean a drop in testosterone over time.
• The long-term alteration of the testosterone profile, particularly the reduction in free, bioavailable testosterone, has several practical health consequences.
• There is scientific consensus that nicotine is not a direct or complete carcinogen, however, it remains to be established whether it plays some role in human cancer propagation and metastasis.

Quitting smoking may help restore your testosterone levels, allowing you to regain muscle strength and potentially even increase your muscle mass. The impact of quitting smoking on testosterone levels is still being studied, but the potential benefits are promising. The evidence points towards smoking potentially undermining your testosterone levels in multiple ways. While tobacco use and its impact on testosterone levels are important, it’s just one piece of a larger puzzle. Clinical studies exploring the relationship between nicotine use and testosterone levels often show a difference between total and free testosterone measurements. Our offerings and global regulatory expertise help you demonstrate that your products meet requirements under the new regulations. A 24-month effective date will apply to consumer products imported into a Foreign Trade Zone1 (FTZ) and subsequently entered for consumption or warehousing.The eFiling program will apply to all imported consumer products subject to a mandatory safety standard, including de minimis shipments. This provides guidance on the applicable technical standards and requirements for operating SRD’s, including emerging technologies. Another study from Sweden showed that men using chewing tobacco had 14% higher testosterone, but also 24% lower sperm concentration. But high SHBG can bind up testosterone, making it unavailable for use. One study found that male smokers had about 15% higher total testosterone than non-smokers, possibly due to increased SHBG (sex hormone-binding globulin). Analysis at the RNA level, however, is limited because levels of transcription are not always reflected by levels of translation and action at the protein level. Upstream analysis and gene ontology isolated matrix metalloproteinase 2 (MMP2) as a potential candidate for promoting tumor progression after nicotine exposure (Bavarvaet al., 2013). A transcriptome sequencing study showed that exposing normal breast epithelial cells (MCF-10 A) to nicotine altered the expression of 138 transcripts by more than twofold. This dysregulation may have an important relationship to addiction and relapse (Lovallo, 2006), as well as adverse health consequences (Rohleder and Kirschbaum, 2006). Average nicotine cigarette smoking may stimulate release of prolactin by increasing endogenous opioids (Pomerleau et al., 1983; Seyler et al., 1986), which in turn may inhibit dopamine release (Shah et al., 1988). The contribution of high prolactin levels to the maintenance of smoking behavior is still debated. In contrast, in our study average nicotine cigarette smoking produced significant and sustained elevations in venous prolactin. This voluntary standard specifies the requirements and test methods for mounted spectacle lenses. Eyewear intended for surface swimming conforming to the requirements of this standard are suitable for surface use and shallow diving only, e.g., from the edge of a pool, and are not suitable for wear when diving from a high board. AFIRM Group (Apparel and Footwear International RSL Management Working Group) published Version 10.1 of its Restricted Substances List (RSL). On Oct. 6, 2025, the Zambia Information and Communications Technology Authority (ZICTA) published a public consultation on the proposed E-Band (71–76 GHz / 81–86 GHz) Spectrum Licensing Guidelines.

On May 27, 2025, the Ministry of Industries (MOI) published S.R.O. No. 148-Act/2025 which amends the notification S.R.O No.. This standard specifies standardized methods for evaluating the performance of electric hobs (cooktops) intended for household use. This standard focuses on mechanical test methods related to installation testing of microduct cabling systems. Studies have consistently shown that smoking increases testosterone in AFAB individuals. As mentioned, both active and passive smoking (also known as second-hand smoking) can cause these nasty effects, with some research even indicating that prolonged exposure and inhalation of cigarette smoke can even affect the onset of menopause (3). But whilst smoking’s effects on the heart and lungs are fairly common knowledge, fewer people are aware that it can also influence the body’s hormones. Despite this, in the UK, as of 2019, 28% of men and 22% of women aged between 25 and 34 years are current smokers, according to published health data in England (1)—and a whopping 175 million people assigned-female-at-birth (AFAB) smoke worldwide. Just like the negative consequences to heart and lung health, smoking can also negatively impact our reproductive health. Consultations with a nutritionist or physician are likely the better solution when seeking assistance with supplement intakes than turning to tobacco products for this goal. Studies have demonstrated that smoking may reduce semen volume, count, and quality, leading to possible fertility problems and loss. People who smoke cigars heavily or inhale deeply can face serious health hazards, including lung, oral cavity, larynx, esophageal cancer, cardiovascular risk factors, and COPD. Many cigar enthusiasts claim they experience increased energy and sexual desire after enjoying a smoke session. On July 3, 2025, the Indonesian National Agency of Drug and Food Control (BPOM) published Regulation No. 18 of 2025 on the Supervision of Tobacco Products and Electronic Cigarettes. This legislation establishes specific dates for the prohibition of PFAS in the covered products and also modifies certain definitions within Subchapter 12A. On June 11, 2025, the Vermont General Assembly approved H.238 (Act 54) An act relating to the phaseout of consumer products containing added perfluoroalkyl and polyfluoroalkyl substances. Smokers had significantly higher total testosterone (TT) and free testosterone (FT) levels compared to non-smokers, even after stratification based on age, BMI, triglycerides, and alcohol consumption. The negative health impacts of smoking, such as lung cancer, heart disease, and other serious conditions, should not be overlooked. Research has shown that men who smoke have significantly higher levels of total and free testosterone compared with men who have never smoked . Before considering any intervention to alter hormone levels, individuals should consult qualified healthcare providers who can evaluate overall health status and recommend appropriate evidence-based treatments. For those with clinically significant testosterone deficiency, consultation with healthcare providers offers safer and more effective treatment options than tobacco use. Without nicotine constricting your blood vessels, circulation improves. After quitting nicotine, your body gradually restores normal hormone production. If you’re worried about your own T levels, there’s good news. However, this boost is misleading, since prolonged nicotine use can disrupt hormone balance. If you’re looking to help your body recover, reducing cortisol and increasing testosterone is key. On July 22, 2025, the Federal Ministry for the Environment, Climate Protection, Nature Conservation and Nuclear Safety (BMUKN) published a Draft of a fifth law amending the Chemicals Act. On July 22, 2025, the European Commission (EC) published a call for evidence for an initiative aimed at simplifying the administrative burden in environmental legislation. On June 27, 2025, the Government of Finland published a proposal to Parliament for legislation supplementing the EU Batteries Regulation and implementing the amendment to the Waste Electrical and Electronic Equipment Directive. Second, nicotine influences the hypothalamic-pituitary-gonadal (HPG) axis, a critical regulatory pathway for hormone production. First, it stimulates the adrenal glands to release catecholamines, which can indirectly impact testosterone secretion. However, chronic use may result in hormonal imbalances or decreased testosterone production over time. However, the relationship remains complex due to the presence of other compounds in tobacco products. Nicotine consumption occurs primarily through smoking, vaping, or using smokeless tobacco.
