Meet the world's first FDA-cleared penile implant for cosmetic male enhancement. You canât predict a single personâs size by race. Differences by racial/ethnic group are small and highly overlapping and do not predict any one personâs size. A partner is not likely to know the size-in-inches of their partnerâs penis unless they pulled out a tape measure, or unless that partner told them what it was (in which case they may or may not have been honest). What someone weighs also isnât going to have much to do with the size of the penis, though thin peopleâs penises may look bigger in perspective to the rest of their bodies, and larger peopleâs penises may look smaller in the context of the rest of their bodies. Iâm not exactly worried about my penis size, Iâm just wondering if it has stopped growing. In studies where people measure themselves and self-report, we usually see larger averages than we do when doctors or nurses are doing the measuring and reporting. Unfortunately, there is no data to support these claims making them selective at best. Data such as the ones reported in this paper are necessary to decondition false assumptions and expectations. Recognizing the complex nature of human sexuality and fostering open communication and emotional intimacy can contribute to a more fulfilling and satisfying sexual experience for individuals and their partners. The Nomogram for penis size was first established by Dr. Veale in 2015 "Stretched flaccid length" (SFL) is the gold standard for predicting erect size in clinics Estrogen-mimicking chemicals in the environment are hypothesized to be reducing average sizes Testosterone replacement therapy does not typically increase penis size in adult men The average increase from flaccid to erect is roughly 47% in length Different techniques have been described to measure the erect length including self-report, in office spontaneous erection, and in-office intracavernosal (i.e., penile) injection.The primary and secondary outcomes clinically measurement of stretched and flaccid penis lengths, and flaccid penis circumference.It isnât even mainly about inches.Another prevalent myth is the belief that dick size can be significantly increased through exercises, pills, or devices.This natural variation means two individuals with the same erect penis length can look completely different when flaccid.Although we found statistically significant differences between different WHO regions regarding penis size and circumference, the importance of the length of the penis as a measure of masculinity and its value in sexuality is limited at best.Although all these premises, body acceptance and selfâsatisfaction are important in confidence and could play a role on sexual life (Veale, Miles, Read, Troglia, Wylie, et al., 2015)(Veale et al., 2014). Another limitation is sexual inexperience among some participants. This could be viewed as a strength, insofar as women did not feel compelled to answer in cases where they did not feel they had a strong enough basis to generate an answer. Expanding this model into preferences pertaining to other domains, or even for other penis shape preferences, appears desirable. These potential complications of a larger penis suggest why the human penis has not evolved to be larger. Finally, women report that condoms increase their experience of pain during intercourse 76, 77. Additionally, the I2 statistic was used to calculate the effect of study heterogeneity. The Q statistic was used to identify heterogeneity within the studies. Was the data analysis conducted with sufficient coverage of the identified sample? Were the study subjects and the setting described in detail? Were study participants sampled in an appropriate way? By using accurate measurement techniques, data-backed penis size chart classifications, and realistic standards, men gain clearer self-awareness and stronger penis size self-esteem.Your penis size is primarily determined by genetics.The Kama Sutra describes a method of enlarging the penis by rubbing it with the bristles on the bodies of insects.And even if it isn't, it by no means reflects your masculinity or your ability to sexually please your partner.One key caveat was that many of the measurements were self-reported, meaning, take it all with a grain of salt.Worldwide, most penises are not circumcised â have not had their foreskins surgically removed, usually at birth or in infancy.Some men are concerned about their penis size, and those who are preoccupied and severely distressed with the size of their penis may even be diagnosed with Body Dysmorphic Disorder.One 2025 compilation reports Thailand as the smallest with an average erect length around 9.43 cm and lists neighboring countries among the shortest . Variations in age demographics could influence penile size measurements, as size can change with age, potentially confounding results. For example, the small number of included studies and the differences in their sizes could explain the observed heterogeneity. Greenstein et al have provided recommendations for the accurate measurement of penis length and girth in clinical research and practice.4 Such recommendations could be used in future research to limit the dispersion and heterogeneity in the data. Focusing solely on penis size oversimplifies the complex nature of human sexuality and reduces it to a physical attribute. It is important to recognize that there is no universally agreed-upon âidealâ penis size for women. The shortest average is for men in Cambodia, with an average of 10.04 cm. How to interpret these findings responsiblyâdata gaps and confounders (5) Shamloul R. Treatment of men complaining of short penis. We found that penile dimensions differ across ethnicities. This study was conducted in a single center where participants were not drawn directly from the general population. Interestingly, we didnât see a pattern or correlation between states and the average penis size by state, though the deep south was guilty of the highest exaggerations. Their conclusion was that the average length of an erect penis is between 5.1 and 5.5 inches. With this in mind, we were interested in finding the average penis size in each state, so we conducted a nationwide survey of just over 1,300 men. For most clinical and counseling purposes, expectations centered on flaccid ~9 cm and stretched/erect ~13 cm are reasonable global reference points, but clinicians should use region-adjusted nomograms and consistent measurement methods when assessing individual patients . Further, perceived penis size was inversely related to penis satisfaction and positively related to lying to others about the size of oneâs own penis. To date, the penisâ connection to masculinity and virility is continually perpetuated throughout popular media (Drummond & Filiault, 2007; Lehman, 1998); thus, it is not surprising researchers have found many men are unsatisfied or feel shame about their penis size (Dotson, 1999; Lever et al., 2006; Mondaini et al., 2002; Pope et al., 2000). On all three psychosocial outcomes (the Prevention/Promotion Scales, the Gay-related Stigma Scale, and the Gay Life Satisfaction Scale), men with below average penises fared significantly poorer than other men. In fact, an early study by Loeb (1899) did report a fairly strong correlation between penis length and body height. As a rule, all bodily structures of any species are adapted to fit overall body size, so in principle, the penis should tend to be longer in bigger men. Dixson cited human penis size from the impressive sample of 2310 summarized by Gebhard & Johnson (1979). Large, recent meta-analyses and clinic-measured studies report a global mean erect girth around 11.7â11.9 cm (â4.6â4.7 inches), while regional and ethnicity-tagged reviews suggest modest mean variations typically within 1â2 cm; methodological differences and sampling biases explain much of the spread .âInternational penis sizes compared.â World Data.Many popular lists (WorldPopulationReview, DataPandas, SupremePenis, VisualCapitalist and others) are useful for a quick snapshot but combine published studies, older reviews, selfâreported surveys and small clinical samples without uniform standards .Penis size is influenced by a combination of genetics, hormones, and developmental factors.A partner is not likely to know the size-in-inches of their partnerâs penis unless they pulled out a tape measure, or unless that partner told them what it was (in which case they may or may not have been honest).When only clinically measured penis size data is used, the variation across ethnic groups becomes extremely small. Clinical and metaâanalytic sources warn that apparent differences by race/ethnicity are often minor and can be exaggerated by poor methods . Ethnicity and geography â small mean differences, big overlap Growth happens mainly in childhood and again around puberty, with size generally stabilizing by the late teens or early 20s . Moreover, studies in Asia have shown that in countries such as Singapore and Hong Kong where the standards of living are higher than that of neighboring regions, people tend to be taller. This caused a 77% decrease in average mammal biomass and a severe loss of ecosystem functionality. The study may inform future policy and practice, supporting more targeted, inclusive, and sustainable HIV responses. Three pro-ICE messages displaying on a digital billboard in San Francisco ahead of Sundayâs Super Bowl are reportedly âraising eyebrows and making some people angry.â How does penis size vary among different ethnic groups and what are the implications? A black manâs large penis pointed to the possibility of truth in other stereotypical notions, âand thatâs a path a lot of brothers donât want to go down,â Raymond said. At one point he told me he liked being average. It would not be until college that I began learning the downÂside, the shadow reality, of the big black penis myth. Members of the Cholomec tribe in Peru and Sadhus men from India attached weights to their penises in an attempt to gain length.In one intriguing 2002 study, Spyropoulos and colleagues reported a significant correlation between penis length and index finger length.Public interest in penis size has fueled stereotypes about certain countries or ethnic groups.âBut weâre talking millimeters of difference, not centimeters or inches.ââNormalâ in the population sense means most adult erect lengths fall near the reported global means with wide variation around them; because withinâgroup variation is large, ethnicity or country does not determine an individualâs measurement .Their meta-analyses for outcomes such as flaccid penis length, stretched penis length, erect penis length, flaccid penis circumference, and erect penis circumference were similar to those of our study; however, our study comprised a larger cumulative sample size.83Glossary of Sexuality TermsDefinitions of sexual terms & acronyms.Research shows that contrary to the widespread belief, women do not care as much as men about penis size. Blood flows continuously through your body's blood vessels. This is needed to sustain life and promote the health of all the body's tissues. The vessels are elastic tubes that carry blood to every part of the body. This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping 5 or 6 quarts of blood each minute, or about 2,000 gallons per day. As of this edition, and as illustrated in Figure 7, average erect penis length increased until the age of 16, a finding that marks a departure from the five previous editions of this page, which reported that such a developmental milestone occurred at age 17. I was initially surprised by the number of responses from teenagers and, although my survey wasnât specifically designed to detect changes in penis size during puberty, the data collected so far has revealed some rather interesting findings. âInternational penis sizes compared.â World Data. âIn my experience as a sex therapist, when size matters, itâs generally because a guyâs penis is too large rather than too small, and that can lead to painful sex.â âThe average vagina is just three to four inches deep, so most guys are doing just fine with their average dimensions,â says Kerner. Furthermore, the most extreme condition, referred to in the study as âmicro-penis,â affects only an estimated 0.14% of the male population.â According to a prominent 1996 study by the University of California, titled âPenile Length in the Flaccid and Erect States,â only 2.28% of the male population should be considered candidates for penile augmentation. Average Penis Size in Asia One of the most reliable ways to understand penis size distribution is through a standardized penis size chart that classifies lengths into medically defined categories. Understanding these facts helps reduce unnecessary worry, improves penis size self-esteem, and provides a realistic foundation for any penis size comparison or penis size chart. â This anxiety is common, but global data shows that the majority of men fall within only a narrow band of sizes. In clinical reality, most individuals fall within the normal penis size range, even though they may assume otherwise. Because of this distortion, people commonly think the ânormalâ size is above the real penis size distribution. Descriptive data are provided regarding the size that women believed was average and the range women indicated for their âsmallestâ and âlargestâ sexual partner. In the current study, womenâs ability to recall penis size was tested by match-to-sample recall, both immediately and after a delay of ten minutes. Since a larger penis size is perceived as more masculine 53, 54, we predict women will prefer a larger penis for shorter-term sexual relationships. Also, most studies of penis size preference have portrayed or asked about the penis in its flaccid state 30, 31. Obesity, for example, can cause fat to accumulate around the pubic area, which may create the impression that the penis is smaller than it truly is. In addition to genetics, environmental and hormonal factors are linked to variations in dick size. Besides, the notion that dick size is directly linked to power, fertility, masculinity, stamina, and social status is another deeply ingrained myth. With a combined adolescent/adult sample size in excess of 3,100 subjects, a high degree of statistical precision has been achieved. Safe, immediately effective penis enlargement procedure performed by physicians in the United States, Canada and the UK. Easily schedule your Upsize⢠consultation or procedure online For more information about penis enlargement in New Jersey, visit our New Jersey clinic page. Dr. Roel Galope performs the Upsize procedure at Upsize New Jersey. Everyone's penis is different, and with good communication, you can find many ways to please your partner. Fat stores at the base of the penis can also make it look shorter than it is. Getting in shape might also help improve your sexual performance. This position focuses more on grinding than thrusting, so it's easier to keep your penis in place. This sex position works well if you have a small penis because it lets you use the full length of your shaft. How to measure the penis? Other studies also found that women prefer a relatively larger penis proportional to body size , especially with respect to circumference (e.g., ).Anyway, Vincentâs penis, when aroused, stood at a slight upward angle, the base somewhat thicker and tapering toward a nice big head.Shading indicates the average penis length and girth in the USA.The Q statistic was used to identify heterogeneity within the studies.Standard deviation for erect girth is approximately 1.29 cmVariability in the intervention effects as a consequence of clinical or methodological diversity among the studies was evaluated by form of heterogeneity .The Brazilian and Nigerian studies rely on localized samples and self-identification, which can produce cultural and selection biases. The stretched penis was measured from the pubopenile skin junction to the meatus with the maximum phallus extension, the depth of the prepubic fat pad from the pubopenile skin junction to the pubic bone, and the penile circumference at the midshaft (in centimeters).14 The data extracted included populations, sample size, study methods, publication year, region of study, and outcome measurement. We included any study which evaluated penis size in different regions of the world. So while race doesnât determine penis size, biology does â and most variation falls well within the average range. The studyâs author emphasized that for this question to be answered properly, research must be done methodically â with large enough populations, controlled variables such as height and body weight, and standardized measurement procedures. Both men and womenâthough studies suggest women are generally less curious â often wonder about the average size of male genitals. "If you are concerned about the size of your penis in terms of sexual performance, itâs important to remember that everyone is different, not just in their sizes, but also in their preferences," said From Mars in its results article. If indeed MSM with above average penises are more likely to assume the anal insertive role, then it is important for them to wear sized-to-fit condoms and use sufficient amounts of lubricant as not to injure their partners nor increase their risk of HIV or STI transmission. Using estimates from the metaregression model, erect penile length increased by 24% over the 29 years of observation was observed (from 12.27 cm to 15.23 cm).Fig. There was no significant association was found between year of publication and stretched penile length (Fig. 2A). Each study measurement was compared to the pooled mean to reveal the SMD estimate under a random-effects model (-0.05 cm; 95% CI, -0.21 to 0.12). Then, we compared each study measurement with the pooled mean using the standardized mean difference (SMD) and 95% confidence intervals (CIs). This analysis was restricted to data collected from original articles that examined menâs penile length. Girth averages around 12 cm (4.7 inches).Questions concerning everything from actual penis dimensions to the possible correlation between size and other parts of the body, to âownerâ satisfaction have been asked in a serious attempt to dissect penis fact from âphallic fallacyâ.Welcome to this website dedicated to the penis.This sex position works well if you have a small penis because it lets you use the full length of your shaft.For girth, wrap a flexible measuring tape â or a strip of paper â around the thickest part of the erect shaft.In fact, performing the measurement during the visit would need the use of drug for the induction of erection or even selfâmade masturbation or during anaesthesia (AkyĂźz, 2020).In particular, the height is proportional to the length of the penis in flaccidity and in erection, and to the circumference in erection. How Men Report Their Size When Asked by Potential Partners or Dates It is believed that diet and lifestyle have a massive effect on the height of a human being, it may be similar to other physical characteristics, such as the penile dimensions. The average male height in Holland (tallest) is 183.8 cm The average male height in India (shortest?) is 162.2 cm Secondary sexual characteristics in males include the growth of pubic hair, facial hair, and voice deepening. Nevertheless, it is not surprising that far more men rated their penis size as above average compared to below average (both in our data and in the Body Image Survey). Though most of the men indicated their penis sizes were average, many (44%) fell outside this ânorm,â either indicating a below average or above average perceived penis size. To that end, a growing body of research has intimated a link between penis size and social-sexual health outcomes (Reece et al., 2007; 2008), though there has been surprisingly little research with MSM (Drummond & Filiault, 2007). Although there are methods such as hormone therapies, surgeries, and other procedures to enlarge the penis, it's important to understand that these interventions come with hazards. Just 14% of respondents preferred their partner's penis to be bigger, and 2% preferred it to be smaller. Knowing how to measure your penis accurately is essential to finding condoms that fit comfortably and securely. It is crucial to rely on scientific evidence rather than hearsay or cultural ideas, even if there are many myths about the length of the penis. Factors that influence appearance (that you can control) Multiple analyses compiled here report statistically measurable differences in mean penile length or circumference across groups. Available sources converge on a global mean erect length near 13â14 cm and show regional patterns (higher reported means in parts of Africa/Latin America; lower in East/Southeast Asia), but countryâbyâcountry rankings are fragile because of mixed measurement methods and variable sample quality . Media and dataâvisual sites tend to repackage the same pooled inputs (Veale et al., Lynn, national surveys) and may omit methodological caveats or sample sizes, which exaggerates apparent precision . There are several implications of these data for males interested in long-term female partners. There may be other biases in the sample related to the recruitment method and sample size that were not identified. This inexperience could underlie some of the size preferences observed. Most men measured their penis while alone, using hand stimulation to become erect. Patients â¤Â 15 years with erectile dysfunction, previous pelvic surgery, suspected hypogonadism, penile disease or deformity were excluded. True dimensions of the penis have always aroused a lot of interest in the general population, especially for penile augmentation (Azab et al., 2021; Zhang et al., 2019). It, therefore, appears that men tend to underestimate their dimensions and that they are more interested in their size than women. However, only 55% of men were satisfied with the size of one's penis (Lever et al., 2006). Then, the aim of the present study was to evaluate the size of the penis at rest and in erection of Italian men. However, penis size is taboo in our society and in most cases the measurement is taken subjectively for comparison with colleagues or friends. Mean (standard deviation SD) flaccid penis length was 9.47 (2.69), mean (SD) flaccid penis circumference was 9.59 (3.08), mean (SD) erect penis length was 16.78 (2.55) and mean (SD) erect penis circumference was 12.03 (3.82). A paper by Tatu Westling makes the ludicrous claim that a countryâs economic growth is inversely correlated with penis size based on data from this website. A study by Richard Lynn claims to have found scientific evidence that there are substantial differences in the average penis length of men from different races. But what Iâd encourage you to do is to remind yourself that again, when it comes to who is the most concerned with penis size, itâs always been and probably always will be men. If you really want to impress someone, youâre not likely to do that by bragging about your penis size or by being obsessed with your penis. Another big cause of penis worry for younger men appears to be rooted in worries about sex when it hasnât been experienced at all, or when ideas about genital intercourse arenât so sage, like the idea that any given size of penis alone has a lot to do with a partnerâs sexual satisfaction. On average, when very aroused, the distance from the vaginal opening to the back of the vagina is about seven inches at a maximum, though it can stretch an inch or two beyond that to accommodate a longer penis than seven inches. If you hear partners reporting that they have had partners with 11-inch penises, you can be pretty sure theyâre either not being honest, or their idea of what 11 inches is isnât so accurate. Average girth is possibly around 11 cm (4.3 inches). Average girth is possibly around 13 cm (5.1 inches). A 2014 study in the US found no significant racial differences between white men. Studies using selfâmeasurement or online selfâreports systematically overestimate length compared with clinicianâmeasured samples; some country databases mix methods and so produce divergent rankings . Penis size figures prominently in discussions of the evolutionary biology of human reproduction and mate choice. âRegardless of size, most intercourse positions fail to directly stimulate the clitoris, the epicenter of the female orgasm,â says Kerner. âItâs those sorts of messages that get internalized and affect sexual self-esteem.â Different techniques have been described to measure the erect length including self-report, in office spontaneous erection, and in-office intracavernosal (i.e., penile) injection. In order to reach the erect length, a minimum tension force of 450 g a force during penile stretching is required. While erect length is fixed, investigators have noted the subjectivity and variability of stretched length. 2Meta-regression model for mean (A) stretched length and (B) erect length over the year of publication. 2Meta-regression model for mean (A) stretched length and (B) erect length over the year of publication.Fig. Not all erections that happen to a given person are the same size all the time. Penis size also can differ a bit for one person from day to day when weâre talking about erections. Like most of our bodies, the size of someoneâs penis is mostly determined by genetics. People with penises will usually be done with puberty by the time theyâre 20â25, and when youâre done with it can vary, and is influenced by when you started. As an additional safeguard, the bottom 1% (for those 18 years and older) and top 2% (for all age groups) of each of the five penile measurements studied have also been excluded from the analysis. In a number of the analyses that follow, penis size has been classified according to the subjectâs perceived endowment status (ref. question 43 of the questionnaire). Questions concerning everything from actual penis dimensions to the possible correlation between size and other parts of the body, to âownerâ satisfaction have been asked in a serious attempt to dissect penis fact from âphallic fallacyâ. For those new to this site, the discussion below pertains to the results of the most exhaustive penis size survey conducted to date. âHuman penis size.â Wikipedia, The Free Encyclopedia. Australia stands at 43rd with an average of 5.7 inches (14.46 cm). Over 40 studies were analyzed by German researchers to compile this data. Across sources the consistent message is that individual variation exceeds typical between-region differences, and that psychosocial and relational factors often matter more in practice than small average differences in length . Those country-level claims rest on uneven data density and mixed methodologies, meaning national rankings can be driven by a few small studies or unrepresentative samples. And even if it isn't, it by no means reflects your masculinity or your ability to sexually please your partner. Note also that that greatest effect of penis length on attractiveness was found with a small penis, not a large one. Although the study by Mautz and colleagues is a welcome step forward, many questions remain unanswered. It is notable, however, that the relationship between penis length and attractiveness was not linear. And Lin sometimes looks even shorter than his actual six feet three inches because, perhaps, his color is his size. In his last novel, âJust Above My Head,â James Baldwin writes, regarding the mystique of the black male penis, that âit was more a matter of its color than its size . Yet whenever I looked down there, espeÂcially unaroused, my penis often seemed undersized to me. My ruler told me I was average, if indeed average was between five and seven inches in length and five around, as is almost universally agreed upon. Beyond shifting ranking order, these measurement corrections also impacted our volume calculations, potentially leading to other distortions in our comparisons.Below are the averages for each racial or ethnic group.All measurements showed variation by geographic region.However, to have a general idea of what is normal/average penis sizes for different ethnicities, we can use the mathematical principles of the mean and standard deviation to assess the ranges of penis sizes for different ethnicities.The Republic of the Congo ranks 2nd with 17.33 cm (6.82 inches). Figure 3 illustrates the bell-shaped distribution of erect penis lengths, thereby justifying the use of the parametric statistical tests that follow. Blatantly fraudulent responses (from 17 year old lawyers or those claiming âAmerican Zulu warriorâ ancestry, for example) are excluded from entry into the database as are penis lengths in excess of 360mm (14.2âł). The inclusion of minimal, and particularly maximal penile dimensions have caused many of you to question the validity of my data. Studies on what size penis do women prefer and penis size and sexual satisfaction reveal that width often matters more than length, and most partners are satisfied within the normal penis size range. Whether itâs a topic of scientific study or just a lively discussion among friends, the concept of âaverage penis sizeâ varies significantly across different cultures and countries. These measurements are typically collected in both flaccid and erect states, though erect measurements are considered more relevant for comparative studies. Ecuador has the biggest average penis size with 17.59 cm (6.93 inches), while Thailand has the smallest penis average at 9.43 cm (3.71 inches) â a difference of 8.16 cm. As has been suggested by other studies, the penile measurements may be affected by temperature, arousal state, body size and investigator factors 5,35,90. Among the studies included, fourteen 21,32,34,37,38,39,40,44,53,60,62,69,79,81 and six 12,26,41,65,70,78 reported measurements obtained with penile injections and spontaneous erections, respectively. The 2015 systematic review that used clinician measurement reported erect averages of 13.12 cm and stretched averages near 13.24 cm â numbers that are close but only meaningful when methods are uniform . Black men of African descent seem to have larger than average penises. Girth averages around 12 cm (4.7 inches). (What Race has the Biggest Penis Size?)Discussing penis size can be a sensitive topic that men avoid. Some large crossâpopulation compilations and niche analyses claim statistical differences by region or ethnicity, but methods, sampling and potential biases vary widely across that literature . Current gaps include lack of harmonized ethnicity coding, inconsistent measurement protocols, and underrepresentation of some regions and subpopulations; meta-analyses grouped by WHO region help but donât resolve ethnic heterogeneity . For clinical assessment, body-image counseling, and public understanding, the salient fact is that most men fall near the population mean with substantial individual variation, so ethnicity-based expectations are misleading . The balance of high-quality evidence favors small mean differences and large within-group spread . Just as boys may wonder about how their penises develop, lots of girls ask the same thing about their breasts. Penis size becomes a problem only if it interferes in sexual intercourse. Itâs also worth pointing out that there is no correlation between penile size and race. Many factors can cause a temporary shrinkage of two inches or more, for instance cold weather or going swimming, so you neednât worry if you happen to fall short of the average figure. Studies conducted suggest that 75% of men are not satisfied with the size of their penis. Large meta-analyses that pool clinical measurements report regional patterns with Americans and some African and South American cohorts showing larger mean stretched or erect lengths, while East and Southeast Asian cohorts tend to cluster lower . The goal of this project is to provide a simple, interactive way to visualize the average penis size in the world. They found no convincing support in the data for the idea that penis size is correlated with the length of oneâs index finger or the ratio of the length of the second and fourth fingers. Furthermore, with an average length of 5.2 inches for an erect penis, 68% of men measure between 4.5 and 5.8 inches and 95% are in the 3.9- and 6.5-inch range. This study established a reference range for penile dimensions which will help when counseling patients worried about their penile size or seeking penis enlargement surgery. The poll also had male respondents (also more than a thousand), and they were asked how they felt after reading the womenâs responses regarding penis size. Also, 61% of them have confided that they have dumped or refused intercourse with males with penis sizes below their expectations. In the previous section, it seems that BJUI studies implied that most women are not that worried about their partnersâ penile size. On the flip side, most of the female respondents in the study (85%) said that they were satisfied with their partnerâs penis size. Studies examining average penis size, including both average erect penis size and average flaccid penis size, reveal that the majority of men fall between a narrow band of measurements. By following correct measurement methods, individuals gain clarity and confidence and can accurately compare their results to average erect penis size, average flaccid penis size, and worldwide human penis size data. Worldwide measurements show that the average erect penis girth falls between 4.5â4.8 inches (11.5â12.2 cm), forming the center of the penis circumference distribution. Data collection on average penis size involves not only different sample sizes, but also differences in the way these measurements are obtained. It is important to note that these measurements are just averages and that there is a wide range of normal penis sizes. If youâre still feeling like you just canât let go of big worries or fixations on your penis size or shape, Iâd just remind you that like it or not, like your height or the length of your fingers, you canât usually change those things about your penis once itâs done growing. Like anything else, penises vary when it comes to where theyâre most sensitive, and people also vary not only in where their penises feel most sensitive, and with what stimulus, but even if their penis is their favorite body part when it comes to sex! While it sometimes takes care of itself over time, when it doesnât, there are treatments for Peyronieâs, so if you think you may have this â though itâs rare in younger people (the average age it develops is around 55), and only occurs in 1-3 out of every 100 people with penises â talk to your healthcare provider. In addition, some reports (9) reveal that penile length was negatively correlated with age, which is validated in our study; however, another showed (7) that penile length has a positive correlation with age. Some studies (6-8) report correlations of penile dimensions and somatometric parameters. In this respect, our study could be used to counsel adult men and help relieve unnecessary concerns of penile inadequacy. Shamloul (5) performed a study on 92 men complaining of a short penis. Regarding the erect penis length and circumference, we could not find any statistically significant difference between the regions. Indeed, we detected considerable heterogeneity and dispersion in penis size within (WHO) regions. A serious limitation to our findings is the lack of standardization for measuring penis size in different situations,4 which may have led to a systematic bias. Men who have concerns about their penis size may experience anxiety, self-esteem issues, and feelings of inadequacy. The topic of penis size is often a subject of curiosity and discussion among individuals. Historically, men from places all around the world have used ill-advised techniques to increase the size of their penises. This can be an unhealthy and often unnecessary fixation, especially because most men who think their penises are too small have perfectly normal-sized penises. Unfortunately, general curiosity can sometimes give way to full-on obsession and anxiety about penis size. They found even though 66% of men rated their penis size as average, 46% of these same men desired a larger penis and 45% of all men desired a larger penis. Though most men felt their penis size was average, many fell outside this ânorm.â The disproportionate number of viral skin-to-skin STIs (HSV-2 and HPV) suggest size may play a role in condom slippage/breakage. Survey data from a diverse sample of 1,065 men who have sex with men were used to explore the association between perceived penis size and a variety of psychosocial outcomes. Yet, there has been little research among men who have sex with men assessing the association between penis size and social-sexual health. The average penile girth was about 4.8 inches (12.2 cm). These data highlight the need to better understand the real individual-level consequences of living in a penis-centered society. Further, size played a significant role in sexual positioning and psychosocial adjustment. "It would be good for women to have good data to show, 'Hey, there's a lot of diversity for women's genitals, just like there are for men's," Herbenick said. The study found that other characteristics of a man, such as his race or orientation, weren't good predictors of his member's size. The situation with regard to erect penis length beyond the age of 50 remains somewhat nebulous. The apparent variation in average size between the ages of 16 to 49 was due to random sampling error and was not statistically significant.. As we can see from figure 4, there was no statistical difference in erect penislength amongst the three groups. Top 10 Countries with the Longest Average Penis Size: Dozens of studies into average penis size came up with varying results. The results below are relevant in 2023 and still represent the best scientific data on penis sizes among different peoples and races. Some scientific and commercial research looked into ranges, the standard deviation of penis sizes, both length, and circumference. As mentioned above, chances are high that your penis size falls within the range of averages. Likewise, with penis sizes, it is difficult to estimate, and therefore whatever comments we may hear from our sexual partners about their previous partners could be ignored. Close behind is Afghanistan at 13.69 cm, followed by Japan with an average of 13.56 cm. All the study procedures were carried out in accordance with the Declaration of Helsinki (2013) of the World Medical Association and participants provided written informed consent after accepting to participate. In particular, temperature, level of arousal and previous ejaculation could also affect the penile dimensions. Twenty-three studies evaluated volunteers while thirty-six studies reported data from men evaluated for urological reasons. Sensitivity analyses with and without each study were performed to investigate for any size-effect influences and outlier effects, but no major differences were observed. Articles were excluded if they were based on a self-measurement and if they reported measurements done after major pelvic surgery. About 80 percent of men have a blood penis and live predominantly in cold regions. During an erection, a relatively large amount of blood flows into the erectile tissue, causing it to grow. The terms blood penis (so-called "grower") and flesh penis (the "shower") are often used for this. Mathematically speaking, the stiff length of 13.6 cm is about 1.5 times as long as the flaccid length (Ă 9.2 cm). The most recent studyâs authors acknowledge that some of the volunteers may have taken part because they were more confident with their penis size than the general male population. Previous studies that have asked about the importance of penis size have shown itâs a much less important issue for woman than it is for men. When it comes to penis size, while thereâs a universal intrigue, the importance it holds in sexual satisfaction varies across individuals. Commercial sites and clinics sometimes present larger averages or race-specific breakdowns that support product or service offerings (e.g., enlargement interventions), creating an incentive to emphasize bigger differences . Popular belief that average erect length exceeds 15 cm (6 in) is contradicted by clinician-measured reviews â self-report bias inflates lay estimates, and many visualizations do not separate clinician vs. self-reported data . Most states fell between 6 â 6.9 inches. Now that you have a frame of reference to keep in mind, letâs get to our own data! Alternatively, most surveys are self-reporting (like ours!) which gives respondents the opportunity to lie about the length of their penis. Large, recent meta-analyses and clinic-measured studies report a global mean erect girth around 11.7â11.9 cm (â4.6â4.7 inches), while regional and ethnicity-tagged reviews suggest modest mean variations typically within 1â2 cm; methodological differences and sampling biases explain much of the spread . The evidence shows small average differences in penile girth across populations but heavy overlap between individuals, meaning ethnicity is a poor predictor of any one person's size. Recent research has highlighted variations in average penis sizes worldwide, from Colombia to Cambodia. These reviews report larger mean stretched or erect lengths in the Americas and some African samples compared with smaller means reported in many Asian samples, but they also flag moderate to low quality evidence from many constituent studies and inconsistent measurement protocols . The net effect is that apparent geographic differences often reflect how studies were done â measurement technique, volunteer bias, and whether researchers used clinical or self-reported data all matter . Philippe Rushtonâs râK lifeâhistory framing explicitly interprets those pooled differences as part of a larger evolutionary argument linking multiple traits across ârâKâ continua, and several papers and online reposts reproduce tables showing mean differences across dozens of populations . Welcome to this website dedicated to the penis. The parallelism with foot size is equally unclear. A relationship with body mass index has almost never been found. Some studies even explicitly state that they did not find a correlation. Are there significant regional or ethnic differences in average penis size? Most reputable studies rely on medical measurements taken under controlled conditions rather than self-reported data, which tends to be exaggerated. A 2024â2025 systematic review and metaâanalysis reframes the question by aggregating studies by WHO region and measurement type, finding largest stretched and flaccid measures among Americans in pooled data and urging adjustment of norms by geography . Several papers from the early 2010s report quantitative differences among broad racial categories and present average values for erect length and girth, asserting greater averages for Africanâdescent groups versus European and East Asian groups . Some have also suggested that the porn industry contributes to unrealistic expectations of penis size and the belief that size is the most important factor when it comes to a sexual partnerâs pleasure and satisfaction. So, what is the average penis size? The most recent comprehensive synthesis included in the materials is a 2025 systematic review and metaâanalysis finding regional variation and identifying Americans among the larger mean stretched lengths and flaccid circumferences; this is the strongest contemporary aggregation in the file because it uses modern metaâanalytic methods to pool heterogeneous studies . Major U.S.-based measurement studies and recent systematic reviews provide broad averages by country or WHO region rather than rigorous, representative splits by race or ethnicity within the U.S., making direct ethnic comparisons problematic. So, those with larger penises (and some even with average-sized penises sometimes), need to bear in mind that it may or may not even be comfortable for partners to have a penis pushed all the way inside an orifice to the base. The term âjelqingâ refers to a set of penis stretching exercises that some believe can make the penis bigger.Would-be participants were excluded if they suffered from erectile dysfunction or had any physical abnormalities, including implants.WorldPopulationReviewâs summary of past U.S. work likewise notes differences among White, Black, Asian, Native American and Pacific Islander/Hawaiian men of less than an inch in one cited 2014 sample of ~1,600 men .A cross-sectional, street-intercept method (Miller, Wilder, Stillman, & Becker, 1997) was adapted to survey 1,065 gay and bisexual men at a series of gay, lesbian, and bisexual (GLB) community events in New York City in the fall of 2006 through the Sex and Love Study, version 5.0.Asian populations have a statistically lower measured average in clinical settings near cmThe erect length of your penis will also increase, but usually to a lesser extent.Concern about penis size is widespread among men.The other American-related studies were from the USA.In contrast, some earlier or non-systematic studies claim stark differences â for example, categorizing groups into broad racial typologies with large size disparities â but these are based on limited data or theoretical assertions and have not been reproduced in large, clinician-measured meta-analyses .The review cautions about regional aggregation and sampling differences, which can produce misleading impressions if interpreted as absolute national rankings . Why Are We So Obsessed with Penis Size? A total of 4,685 men living in Italy and who have been visited at the Italian urology operating units were involved in the study between January 2019 and January 2020. This section collects any data citations, data availability statements, or supplementary materials included in this article. Indeed, emerging data suggest that diverse prenatal or postnatal exposures may influence pubertal timing 99,100,101,102. Investigators have hypothesized sedentary lifestyle/obesity or increasing exposure to hormone-disrupting substances may play a role 96,97,98. For example, women with wider hips tend to have a higher proportion of one-time sexual partners . These appear finely tuned to detect variability in circumference, whereas the vagina is less sensitive to differences in other stimuli such as vibration or warmth . A larger circumference might stretch the vaginal opening such that the deep structures (clitoral crura and vestibular bulbs) are more stimulated, and the clitoral glans is more stimulated by penis movement . Youâve got to already know that one preference for one kind of body part or one area of appearance doesnât usually dictate how someone feels about a whole person. SPS, or small penis syndrome, is what sexologists call it when someone has a pervasive obsession or preoccupation with the idea that their penis is too small. Some people find taller people more attractive than shorter people, brunettes more compelling than blondes, prefer small noses, big noses, bigger lips, smaller lips, big butts, little butts, body hair, no body hair. That isnât to say some people may not still have certain penis preferences or likes. When it comes to the appearance of our own sexual parts, the old adage âbeauty is in the eye of the beholderâ appears to often be false. Global data shows the average flaccid length is around 3.3â3.8 inches, yet the variation can be so wide that itâs nearly impossible to draw meaningful conclusions from a single measurement. When discussing average penis size, itâs important to understand that average flaccid penis size is one of the most misleading metrics. These categories are based on standard deviation of penis size from global studies, meaning the vast majority of people fall within the average or slightly above/below average ranges. Another condition often misunderstood is the buried penis, where excess skin or fat tissue around the pubic area partially hides the penis, making it appear smaller than it truly is. Large-scale surveys consistently demonstrate that most women do not place high importance on length. This involves placing a ruler along the top of the penis and pressing gently into the pubic bone until the ruler stops. Because many misconceptions come from incorrect methods, specialists recommend using standardized clinical techniques rather than self-reported approaches. Nevertheless, the human penis is the widest compared to other primates. So broader comparison suggests that a male chimpanzee also has a longer penis than a man. A male bonobo accordingly has a longer penis than a man. Is that why we see hordes of men seeking penis reduction?
