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. 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. Show discussion. Science on NBCNews.

In fact, the penis of the common chimpanzee is no shorter than in humans, averaging Stretched length has correlated with erect length in some cases. American Journal of Medical Genetics. Scientists and suspect it might have something to do with prenatal hormones that affect the structure and size of genitalia, and certain structures of the brain that affect sexual orientation. This is the average penis size. 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.
Peniss aize. When is penis size too small?
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  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 ,   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.

While most of men's worries about penis size centre on the length, women are more interested in width, according to one study.
The study of 50 sexually active undergraduate women reported that for a large majority — 9 out of 10 of the women — penis width was more important to sexual satisfaction than penis length. A study published in the open-access journal PLOS ONE in November took the novel approach of asking women to show their penis size preferences with the use of 3D printed models of 33 different dimensions.
The sizes had been printed across a range from 4 inches to 8. The 3D-printed shafts were in blue plastic so as not to suggest any particular race that might prejudice the women's ideas of average size.
The 75 women indicating size preferences from the 33 blue models chose slightly differently depending on the kind of relationship they were thinking about and in any case showed they desired a size that turned out to be only slightly above the averages found across studies :. A number of different studies have sought to determine an average penis size.
One published in took measurements of 3, young Italian men aged between 17 and 19 years. It found the median average length of flaccid penises was 9 centimeters 3.
Another study examined a different population, of physically normal Indian men, and sought to compare its results with size findings in other countries. The results, the authors of the study said, "will help in counseling the patients worried about the penile size and seeking penis enlargement surgery. The findings, published in Nature, included a table that listed previous findings on penis dimensions around the world. Click here to see the table.
Of the 16 studies they cited, from various countries, the earliest was carried out over a hundred years ago and published in The authors of the study from India wrote that the definition of normal penile size was of "considerable interest" as there was a "steady increase in the number of people complaining of 'short penis' and seeking penile enlargement procedures.
Other research has suggested that most men who seek surgery to lengthen their penis have an overestimated view of what a normal penis size is. In the study of 67 men complaining of a short penis, none was, in fact, found to be severely short.
The authors said there was an increasing number of men seeking surgery to lengthen their penis. In , researchers in Saudi Arabia published the results of a retrospective cohort study of men with an average age of Men were excluded from the study if they were under 18 years old, presented with a complaint of small or short penis, Peyronie's disease , congenital curvature, clinical hypogonadism, previous penile surgery or trauma, or a combination of any of these.
After medically inducing an erection the researchers took measurements and established an average:. The researchers also measured the men's body-mass index BMI , which increases with obesity.
There was a weak correlation between greater BMI and shorter erect penile length when this was measured from the skin over the pubic area, but not when the measurement was made from the bone to the tip.
This suggests that the penis would appear to be shorter when there is more fat under the skin at the visible base of the penis. However, the authors noted that slight decreases in size may be of limited concern to "aging men" - they found "the difference between men of 70 and 20 was less than a centimeter. Research findings on penis size from MNT news. A new finding shows evidence of a link between the relative length of a man's index and ring fingers and a way to predict the length of his penis.
Want a longer penis? Traction beats surgery, say researchers. Men who want surgery to increase the length of their penis should try non-invasive methods like penile traction devices or extenders first, and in some cases, even try therapy to make them feel more confident about their bodies, said Italian urologists in a paper published in the April issue of the British Journal of Urology International.
A lot of men worry about their penis size. But researchers hope the results of a new study, which reveals the average penis length, will reassure many men that they are 'normal.

Fast facts on the average penis size Here are some key points about the average penis size. While 85 percent of women may be satisfied with the size and proportion of their partner's penis, men are less sure of themselves.
As much as 45 percent of men believe they have a small penis. Across studies, flaccid length average from 7 to 10 centimeters 2. Flaccid circumference or girth average ranges from 9 to 10 centimeters 3. Erect lengths average from 12 to 16 centimeters 4.
Average Penis and Erection Size: What’s Normal?
Memorialized in monuments, Grecian statues and bathroom graffiti everywhere, the penis may be the most famous and well-studied human organ on the planet. But despite its outsized profile in the popular imagination, the male member still has a few secrets left to reveal.
From penis spines to the ideal size and even penis shame, here are eight wild facts about the male sex organ. The average erect penis is about 5. But variety is the spice of life, and men in that study had members that ranged from 1.
Not all erections were created equal. Those who measured their penises after oral sex or intercourse sported larger penises than those who relied on fantasy alone, the study found. And because it reduces blood flow to the penis, smoking can shorten the average penis by up to 0. When it comes to penises, size does matter — at least for some women. Women who are more likely to have vaginal orgasms say it is easier to orgasm with men who have longer penises, according to a study published in the Journal of Sexual Medicine.
Though it's not clear exactly why, a longer penis may be better able to stimulate the vagina and the cervix, study co-author Stuart Brody, a psychologist at the University of the West of Scotland, told LiveScience at the time. In a study detailed in the journal Proceedings of the National Academy of Sciences, researchers reported women said the ideal penis size varied with a man's height, with a larger organ looking better on taller men.
Very rarely, a man may be born with two penises, a condition that affects every 5 million to 6 million males and is known as diphallus. Unfortunately, this condition doesn't mean double the fun: Both organs are rarely fully functional, and the condition often comes along with other anomalies in the genital area that require surgery to correct. Men with another penis condition called priapism suffer from a persistent erection that won't go away after four hours. Usually the cause is a failure of blood to return from the penis to the rest of the body, although it is also occasionally found in those with sickle-cell anemia or leukemia.
The situation is usually a medical emergency that requires a shot of pseudoepinephrine to constrict the smooth muscles in the penis.
The penis may have been a lot scarier in humans' evolutionary past. At one point in time, the male penis had spines , but human ancestors lost those prickly structures before Neanderthals and modern humans diverged some , years ago, according to a study published in the journal Nature.
Scientists aren't clear on the function of those spines, but some propose they allowed for quickies because they can create an erection quickly, and are more common in promiscuous species, such as cats tomcats have rather terrifying spines on their penis. Another relic of times past is the penis bone, or baculum.
Though most apes have a bone to keep their member erect, human males lost theirs at some point and now rely on blood pressure for stiffness. In other animals, the penis bone sits inside the body and is pushed out into the penis for an instant, reliable erection. It's still a mystery why males lost this trait, but in "The Selfish Gene" Oxford University Press, , biologist Richard Dawkins proposes the bone-free penis was selected for because it allows females to gauge potential partners' health — those who can't get an erection probably have poor blood flow.
Whether or not men are celibate during the day, their penis is working out at night. Most men have three to five erections a night during the rapid eye movement REM phase of sleep, whether they are dreaming about grandma or supermodel Elle Macpherson. This nighttime action apparently keeps the male member in shape — penises that don't experience regular erections risk losing their elasticity and shrinking.
Because this is such a basic physiological process, many doctors ask whether a man has nighttime erections to determine the cause of erectile dysfunction. When baby boys are born, the foreskin tissue is fused to the glans of the penis. In the womb, the foreskin evolves from the same tissue as the clitoral hood. The foreskin's inner surface is made up of mucous membranes similar to those found inside the eyelid or the mouth, making it a moist place.
That unique environment could be responsible for the increased STD transmission rates associated with uncircumcised men in some studies. The foreskin also has an abundance of Langerhans cells, the immune cells infiltrated by HIV. That may explain why circumcised men in Africa have a 60 percent lower rate of HIV infection from heterosexual intercourse. The American Academy of Pediatrics does not endorse or discourage circumcision, noting that circumcision carries both small risks and benefits.
But "intactivists" disagree, citing studies that suggest circumcised men experience less sexual pleasure. Many doctors, however, are skeptical of this research, because the methodology has been problematic or biased. The old adage is true: Some men are "showers" and others are "growers. However, a stretched-out penis is a good predictor of its ultimate erect size, a study in the International Journal of Impotence Research found.
Penis anxiety is real and common: In one study published in September in the Journal of Sexual Medicine, 30 percent of a sample of British men were very dissatisfied with their penis size. The study found no link, however, between size anxiety and actual penis size. Some men were so stressed about their penis size that they feared others would be able to see the size or shape of their genitalia through their pants. Live Science.
