Average penis size has increased — and Ozempic could be to blame, experts say

Ozempic might shrink waistlines, but it seems to bulge another body part.

In a recent Reddit thread, male Ozempic users claimed that the weight-loss drugs helped their penises grow.

“I recently measured myself down there and noticed I gained about one inch,” a person proudly shared on the forum.

Although there hasn’t been enough research done on the correlation between semaglutide and men’s genitalia measurements — the average penis size is continuing to rise, and some experts think Ozempic might actually have something to do with it.

The average penis has grown nearly 10% from 5.17 inches to 5.63 between 2022 and 2024 in the UK, according to diabetes.co.

And they’re not the only ones seeing this increase.

The data also revealed that Venezuelan men experienced a massive increase from 1.42 inches to 6.67 inches, within those two years.

Dr. Richard Viney, a consultant urological surgeon at the Queen Elizabeth Hospital in Birmingham, thinks Ozempic and similar drugs could be to blame.

“Men’s penises shorten as they get older (due to) increasing body fat and increasing prostate size drawing the penis back into the body,” he told diabetes.co.

“It is theoretically possible that new drugs like Ozempic and Wegovy, which are used to treat diabetes and obesity, respectively and can cause people to lose weight, could also be a factor. As men lose weight, their penises appear larger.”

However, in 2023, research published in the World Journal of Men’s Health revealed that the average size of what a guy is packing has grown 24% over nearly 30 years.

And that sort of increase has health experts concerned — especially because even two years ago, they couldn’t put their finger on what the cause of it is.

Speculation around weight loss drugs being the culprit is possible — but the Ozempic trend is recent, and this growth for men has clearly been going on for some time now.

“Any overall change in development is concerning, because our reproductive system is one of the most important pieces of human biology,” Dr. Michael Eisenberg, the study’s author, told Stanford Medicine’s blog Scope.

“If we’re seeing this fast of a change, it means that something powerful is happening to our bodies.”

Other possible causes could be chemical exposure from pesticides or hygiene products, Eisenberg hypothesized, which can disrupt the hormone-regulating endocrine system.

Time will only tell if Ozempic or other lifestyle factors are to blame for well-endowed men.
