“I was in the pool!” George Costanza’s distress at the “shrinkage” of his after exiting a cold pool was hilarious in the 1994 Seinfeld episode, but for many men concern over the length and girth of their reproductive organ is no laughing matter. Now, a new study could assuage such worries with what may be the most accurate -size measurements to date.
Many earlier studies relied on self-reporting, which doesn’t always yield reliable results. “People tend to overestimate themselves,” says David Veale, a psychiatrist at the South London and Maudsley NHS Foundation Trust. So when Veale and his team set out to settle the score on penile proportions, they decided to compile data from clinicians who followed a standardized measuring procedure.
Published today in the British Journal of Urology International, their new study synthesizes data from 17 previous academic papers that included measurements from a total of 15,521 men from around the world. The data enabled the researchers to calculate averages and model the estimated distribution of penile dimensions across humanity. “It still just strikes me how many men have questions and insecurities and concerns about their own size. We actually do need good data on it,” says Debra Herbenick, a behavioral scientist at Indiana University, Bloomington, who was not involved in the study.
According to the team’s analysis, the average flaccid, pendulous is 9.16 cm (3.61 inches) in length; the average erect is 13.12 cm (5.16 inches) long. The corresponding girth measurements are 9.31 cm (3.66 inches) for a flaccid and 11.66 cm (4.59 inches) for an erect one.
A graph of the size distribution shows that outliers are rare. A 16-cm (6.3-inch) erect falls into the 95th percentile: Out of 100 men, only five would have a larger than 16 cm. Conversely, an erect measuring 10 cm (3.94 inches) falls into the 5th percentile: Only five out of 100 men would have a smaller than 10 cm.
All length measurements were made from the pubic bone to the tip of the glans on the top side of the . Any fat covering the pubic bone was compressed before measurement, and any additional length provided by foreskin was not counted. Circumference was measured at the base of the or around the middle of the shaft, as the two sites were deemed equivalent.
The researchers concluded that there was no strong evidence to link size to other physical features such as height, body mass index, or even shoe size. Yes, it seems that the only definite conclusion that can be drawn about a fellow with big socks is that he probably has big feet.
It’s easy to laugh at poor George Costanza for his shrunken manhood, but some reports suggest that only about 55% of men are satisfied with their size. Some seek potentially dangerous surgical solutions to a problem that, according to Veale, is often only in their head. Men “seem to have a very distorted picture of what [size] other men are, and what they believe they should be,” Veale says.
Pornography, in which male performers are often selected for their extremely large genitalia, may be partly to blame. Similarly, Herbenick points to the myriad spam e-mails that assert that 17.78 cm (7 inches) is average for an erection, when in reality such a member would place its owner in about the 98th percentile. It’s best to just ignore those ads in any case, Veale says. “There are no effective lotions or potions or pills.”
