A recent study has found that men’s penis sizes have gotten larger over the last 30 years. While that may sound like good news for size queens, the study’s lead researcher actually worries it may mean that chemicals are screwing with our hormones. Whomp, whomp.
Lead researcher, Michael Eisenberg, MD, a professor of urology at the Stanford University School of Medicine, became alarmed after seeing studies about men’s sperm counts and testosterone levels declining over the last few decades, he told Stanford medical school’s blog.
Other studies he saw indicated higher rates of male congenital birth defects, like hypospadias (when the urethral opening isn’t at the tip of the penis) and cryptorchidism (when testicles don’t fully descend).
So Eisenberg became curious whether studies had looked at other aspects of men’s reproductive health. He decided to look at penile length because previous studies hadn’t taken a hard look at that. (Hehe!)
How about we take this to the next level?
Our newsletter is like a refreshing cocktail (or mocktail) of LGBTQ+ entertainment and pop culture, served up with a side of eye-candy.
His research team looked at data on the penile length of 55,761 men taken from 75 studies conducted between 1942 and 2021. Each study included measurements of men’s flaccid and erect penises, measuring the top side from the tip to where the shaft enters the body.
Researchers found that, over the course of these studies, the average erect penis length increased by 24% over 29 years, from an older average of 4.8 inches to a more recent average of 6 inches. Researchers also found that this lengthening occurred in men of all ages living on different continents around the world.
“To our knowledge, this is the first study to examine temporal change in penile size,” the study’s authors wrote in The World’s Journal of Men’s Health.
But while some men might rejoice over the recent increase in size, Eisenberg says it’s actually quite “concerning” because the increase happened over a relatively short period of time.
“Our reproductive system is one of the most important pieces of human biology,” he told the aforementioned blog. “If we’re seeing this fast of a change, it means that something powerful is happening to our bodies.”
His team’s study didn’t determine what’s causing the increase in size, but he said it could be the effect of hormone-disrupting chemicals in our food and hygiene products or the presence of pollutants in our living environments. It could also be the result of our increasingly inactive lifestyles.
Either way, Eisenberg said, “We must determine the cause of these changes.” He also added, “It’s important to ask if there are similar changes occurring to women’s reproductive organs.”

Self reported sizes are the culprit, not hormones

Put a period on that.

Yep, definitely that and not the 55,000 research subjects.

abfab…men don’t have periods! 😉

So what, then, do you think is causing men to collectively claim their dicks are bigger over the years?

Wouldn’t this mean that fertile women are choosing partners for penis size – a choice unavailable to women who lived before the “sexual revolution” and had no opportunity to “sample the wares?”

If it’s true. Even when participating anonymously, there are social pressures and anxieties that discourage smaller men from participating at all in a study like this. Dick shame/pride is real, and ubiquitous access to pornogrqphy on demand has warped a lot of men’s perspective on the importance of penis size.
30 years is not long enough for any organ to increase by 24%. Even the Green Revolution had a bigger delay when it came to increasing population height and weight from improved access to calories and fewer malnourished people. It took close to 60 years for the Green Revolution to also lead to the obesity epidemic.
Penis size research have had this issue for as long as there have been penis size research. Even when the numbers are not self-reported, all attempts to obtain a single measurement in a neutral environment are inherently flawed when erect penis size varies a lot based on arousal level, which is entirely subjective.

I’m dubious about these stats. There are so many gun nuts in the U.S. that average penis size MUST be shrinking, at least in the Trump states.

the ? is r black men getting bigger? I hope so & so does my ass!
