The most accurate measurement of the size of a human penis can be derived from several readings at different times since there is natural minor variability in size depending upon arousal level, time of day, room temperature, frequency of sexual activity, and reliability of measurement.

When 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 the best research to date on the topic has concluded that the mean length of an erect human penis is approximately 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.

Penis size is positively correlated with increasing testosterone levels during puberty. Perceptions of penis size are culture-specific.

In Ancient Greece and in Renaissance art, a small penis which had not been circumcised was perceived as desirable in a man, whereas a large or circumcised penis was considered comical or grotesque. Ancient Rome may have had a contrary view, and a larger penis size was preferred in medieval Arabic literature. The perception of having a large penis is often linked to higher self-esteem. 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 i.

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 4. 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.

The belief that penis size varies according to race is not supported by scientific evidence. A study noted that contrary to the "popular belief that black people generally have longer penile sizes", in reality "there is no convincing scientific background" to support this idea. A review found that it was not possible to draw any conclusions about size and race from the available literature and that further research needed to be conducted.

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. Variance in size can often be attributed to de-novo mutations.

Deficiency of pituitary growth hormone or gonadotropins, mild degrees of androgen insensitivity can cause small penis size in males and is treated with 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. According to Kenneth Dover's landmark study "Greek Homosexuality", Greek art had extreme interest in the genitals, but was not obsessed with size. CBC Radio has suggested, based on several sources, that ancient Romans had a viewpoint contrary to that of the Greeks. As a witty satire of this fantasy, the 9th-century Afro-Arab author Al-Jahiz wrote: Males may quite easily underestimate the size of their own penis relative to that of others, because of the foreshortening obtained from looking down, due to repeated observation of atypical penises in pornography , or because of the accumulation of fat at the base of the penis.

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. 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.

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 [48] 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 , [51] [52] 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 term size queen is slang for anyone who prefers their sexual partner s to have a larger-than-average penis. 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 cranium. 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, but penis circumference and broken condoms were strongly correlated, with larger sizes increasing the rate of breakage. From Wikipedia, the free encyclopedia.
