Human penises vary in size on a number of measures, including length and circumference when flaccid and erect. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal , time of day, room temperature, and frequency of sexual activity.

Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body.

Measurements vary, with studies that rely on self-measurement reporting a significantly higher average than those with a health professional measuring. As of [update] , a systematic review of 15, men, and the best research to date on the topic, as the subjects were measured by health professionals, rather than self-measured, has concluded that the average length of an erect human penis is Most human penis growth occurs between infancy and the age of five, and between about one year after the onset of puberty and, at latest, approximately 17 years of age.

A statistically significant correlation between penis size and the size of other body parts has not been found in research. Some environmental factors in addition to genetics, such as the presence of endocrine disruptors , can affect penis growth. While results vary slightly across reputable studies, the consensus is that the mean human penis, when erect, is in the range A systematic review published by Veale et al.

Erect lengths in the included studies were measured by pushing the pre-pubic fat pad to the bone, and flaccid or erect girth circumference was measured at the base or mid-shaft of the penis.

One study found the mean flaccid penis length to be 3. The penis and scrotum can contract involuntarily in reaction to cold temperatures or nervousness, referred to by the slang term "shrinkage", due to action by the cremaster muscle. The same phenomenon affects cyclist and exercise bike users, with prolonged pressure on the perineum from the bicycle saddle and the straining of the exercise causing the penis and scrotum to contract involuntarily.

An incorrect saddle may ultimately cause erectile dysfunction see crotch pressure for more information. Neither age nor size of the flaccid penis accurately predicted erectile length. Stretched length has correlated with erect length in some cases. Scientific studies have been performed on the erect length of the adult penis.

Studies that have relied on self-measurement, including those from Internet surveys, consistently reported a higher average length than those that used medical or scientific methods to obtain measurements. The following staff-measured studies are composed of different subgroups of the human population in other words, specific age range or race; selection of those with sexual medical concerns or self-selection that could cause a sample bias.

Similar results exist regarding studies of the circumference of the adult fully erect penis, with the measurement usually taken mid-shaft. In a study of penis size where measurements were taken in a laboratory setting, the average penis circumference when erect was Limited growth of the penis occurs between birth and 5 years of age, but very little occurs between 5 years and the onset of puberty.

Schonfeld published a penis growth curve in Age is not believed to negatively correlate with penis size. A review of the literature found two studies finding height and stretched or flaccid length to be moderately correlated, seven studies finding weak correlation for flaccid, stretched, or erect length, and two studies that found no correlation between flaccid length and height.

One study investigated the relationship with digit ratio and found that men with longer ring fingers than index fingers had slightly longer penises. The belief that penis size varies according to race is not supported by scientific evidence.

A study of men from Nigeria found that the average flaccid stretched penis length of Nigerian males is Androgens like testosterone are responsible for penis enlargement and elongation during puberty. There are certain genes, like homeobox Hox a and d genes, which may have a role in regulating penis size. In humans, the AR gene located on the X chromosome at Xq which may determine the penis size.

The SRY gene located on the Y chromosome may have a role to play. Variance in size can often be attributed to de novo mutations. Deficiency of pituitary growth hormone or gonadotropins or mild degrees of androgen insensitivity can cause small penis size in males and can be addressed with growth hormone or testosterone treatment in early childhood.

Some types of micropenis can be addressed with growth hormone or testosterone treatment in early childhood. Operations are also available to increase penis size in cases of micropenis in adults. It has been suggested that differences in penis size between individuals are caused not only by genetics , but also by environmental factors such as culture , diet and chemical or pollution exposure. Chemicals from both synthetic e. A study by the University of Ankara , Faculty of Medicine found that penile size may decrease as a result of some hormonal therapy combined with external beam radiation therapy.

Perceptions of penis size are culture-specific. The ancient Greeks believed that small penises were ideal. In Aristophanes 's comedy The Clouds , "Mr. Nonetheless, there are indications that the Greeks had an open mind about large penises. Penis size is alluded to in the Bible : [42]. Ezekiel —20 , English Standard Version. Ancient Chinese legend holds that a man named Lao Ai had the largest penis in history and that he had an affair with Queen Dowager Zhao c.

In medieval Arabic literature , a longer penis was preferred, as described in an Arabian Nights tale called "Ali with the Large Member". As a witty satire of this fantasy, the 9th-century Afro-Arab author Al-Jahiz wrote: "If the length of the penis were a sign of honor, then the mule would belong to the Quraysh " the tribe to which Muhammad belonged and from which he descended. The medieval Norsemen considered the size of a man's penis as the measure of his manliness, [50] and a thirteenth-century Norse magic talisman from Bergen , a wooden stave inscribed with writing in runic script , promises its wearer: "You will fuck Rannveig the Red.

It will be bigger than a man's prick and smaller than a horse's prick. During the Renaissance , some men in Europe began to wear codpieces , which accentuated their genitals. Males may quite easily underestimate the size of their own penis relative to those of others. A survey by sexologists showed that many men who believed that their penis was of inadequate size had average-sized penises. Widespread private concerns related to penis size have led to a number of folklore sayings and popular culture reflections related to penis size.

Penis panic is a form of mass hysteria involving the believed removal or shrinking of the penis, known as genital retraction syndrome. At present there is no consensus in the scientific community of any non-surgical technique that permanently increases either the thickness or length of the erect penis that already falls into the normal range 4.

A study undertaken at Utrecht University found that the majority of homosexual men in the study regarded a large penis as ideal, and having one was linked to self-esteem.

One study, Siminoski and Bain , found a weak correlation between the size of the stretched penis and foot size and height; however, it was too weak to be used as a practical estimator. There may be a link between the malformation of the genitalia and the human limbs. The development of the penis in an embryo is controlled by some of the same Hox genes in particular HOXA13 and HOXD13 [64] as those that control the development of the limbs.

Mutations of some Hox genes that control the growth of limbs cause malformed genitalia hand-foot-genital syndrome. In a small study conducted by University of Texas—Pan American and published in BMC Women's Health, 50 undergraduate women were surveyed by two popular male athletes on campus about their perceptions of sexual satisfaction and it was concluded that the width of a penis feels better than the length of a penis, when subjects are asked to choose between the two size was left unspecified.

It was also concluded that this may show that penis size overall affects sexual satisfaction since women chose between the two options they were given. In a cover story by Psychology Today , [67] [68] 1, readers about two-thirds women were surveyed about male body image. Generally, the women polled cared more about width than men thought, and less about length than men thought, although the strength of caring for either among women showed a similar pattern.

A study conducted at the Australian National University , published in early , showed that penis size influences a man's sex appeal, and the taller the man, the bigger the effect. A preference for taller men's larger penis size was notable. The human penis is thicker than that of any other primate, both in absolute terms and relative to the rest of the body. In fact, the penis of the common chimpanzee is no shorter than in humans, averaging The evolutionary reasons for the increased thickness have not been established.

The vaginal canal is believed to have expanded in humans to accommodate the larger size of a newborn's skull. Women may then have sexually selected men with penises large enough to fit their vagina, to provide sexual stimulation and ensure ejaculation. One Australian study of men looked at penis length and circumference in relationship to condom breakage or slippage.

The study found that when used correctly, condoms had a breakage rate of 1. Penile dimensions did not influence slippage, although penis circumference and broken condoms were strongly correlated, with larger sizes increasing the rate of breakage.

What is the average penis size?

Put down the rulers, guys — whether your penis is the "right" size depends on the proportions of the rest of your body, a new study finds. Women rate men with larger penises more attractive, but the returns on bigger genitals start to decrease at a flaccid length of 2.

What's more, larger penises gave tall men a bigger attractiveness boost than shorter men. The study suggests that women's preferences for bigger penises could explain why human males have relatively big genitals for their body size. Studies on women's preferences for penis size have been mixed, with some suggesting that women who frequently orgasm through vaginal stimulation are the pickiest, perhaps because penis size matters for that sort of stimulation. Men typically fret more about size than women , however, at least according to a review article in the British Journal of Urology International.

New research shows that penis size matters to women, up to a point. But studies have relied on questionnaires, which may not always glean honest answers, Australian researchers wrote today April 8 in the journal Proceedings of the National Academy of Sciences.

And in other studies, scientists have asked women to judge the attractiveness of male figures in photos with only penis size varied, when in fact no trait is ever evaluated in a vacuum, the scientists added. To compensate, the researchers, led by Michael Jennions of Australian National University, showed young Australian women life-size computer-generated figures of nude men, varying the figures' flaccid penis size, height and shoulder-to-hip ratio.

Height and shoulder-to-hip ratio have previously been shown as factors used by women to judge attractiveness. The computer simulations varied penis width in sync with length, so that all penises were proportional.

The results revealed that women preferred taller men as well as high shoulder-to-hip ratios meaning that the wider the shoulders were than the hip, the more attractive the man. Shoulder-to-hip ratio was a major determiner of attractiveness , accounting for Though the effect was less extreme, women also preferred larger penises, at least up to 5.

Beyond 2. That's good news for guys, according to a Italian study that found 2. When the researchers controlled for shoulder-to-hip ratio, they found that a larger penis had a greater effect on attractiveness for taller men.

It's possible that a larger penis just looked more proportional on a taller man's body, the researchers wrote, or it could be that women were biased against shorter men to the extent that even large genitals didn't help. Women's own features mattered as well, the researchers found: Taller women were more likely to find taller men attractive. Women with greater body mass per height were slightly more likely than thinner women to weigh penis size more heavily in their judgments of attractiveness, though the difference was small.

The findings might help explain why humans have remarkably large genitalia given their average body size, the researchers wrote. Male humans outgun any other primate species: For example, male gorillas can weigh as much as pounds kilograms , but their erect penis length is only about 1. Human males weigh about half of what gorillas do, but studies peg average erect or flaccid-but-stretched penis length from 4. Evolutionary biologists theorize that large human penises might help remove sperm from competing males during sex, but in an era before clothing, women may have been drawn to mating with men whose genitalia caught their eye.

Men with larger penises, then, may have passed on their genes more readily, resulting in the large-genitals trait being handed down the generations. In other words, guys may have women to thank for their greater-than-gorilla-sized genitals. Original article on LiveScience. US Edition U. News U. HuffPost Personal Video Horoscopes.
