Ozempic penis

If you’ve heard the rumors about “Ozempic penis” — the idea that your penis gets larger when you start taking Ozempic — you might be wondering if such a miracle could possibly be real. And the answer is… complicated. 

First, a dose of the cold, hard truth: Once you’ve gone through puberty, your penis isn’t truly going to grow any longer or girthier without interventions like surgery, filler, or penile implants. But Ozempic can impact how long your penis looks. We’ll explain how this works and what you can expect. Keep reading. 

“Ozempic penis” isn’t a medical term, but some people on social media have used it to refer to increases in penis size after taking Ozempic.

One Reddit user recently shared on the r/Ozempic subreddit, “I recently measured myself down there and noticed I gained about 1 inch.” Another commenter shared, “Two and a half months in and I’ve definitely gained length!”

Here’s the truth: Ozempic penis — a measurably larger penis that’s the direct result of weight loss medication — isn’t really a thing.

 “Losing weight with Ozempic — or any other method — won’t make your penis physically grow. Penile length is determined genetically and doesn’t change with weight loss,” shares Justin Houman, MD, FACS, a urologist who specializes in men’s health. 

However, he notes, there’s a bit more to the story. He explains that many men have a “hidden” portion of the penis that’s obscured by belly fat above the base of the penis. “When you lose weight, especially in the lower abdomen, more of the penile shaft becomes visible, giving the appearance of increased length,” he says. “I’ve seen patients gain over an inch of visible length simply through weight loss.”

As Dr. Houman notes, losing weight with Ozempic or other methods won’t really increase the size of your penis, though it can increase the visible length. 

Your penis is done growing naturally once you’ve completed puberty, which is around age 19 or 20, according to research (though this can vary in different parts of the world). Once your penis has reached its full length, it’s unlikely to grow any longer. (And for what it’s worth, whatever length you are is probably perfectly fine  — research has found 85% of women are satisfied with their partner’s penis size, and only 21% consider penis length to be important to sexual satisfaction). 

But why might people feel as though their penis is bigger and better on Ozempic? There are a few reasons why this could be. 

• Losing weight around the abdomen can make your penis appear larger. Excess fat in the abdominal and pubic areas can build up around the base of your penis, which hides some of the length. The term for this is “buried penis,” a condition where fat and skin tissue hang down and conceal part of the penis. When this condition is caused by obesity or overweight, healthcare providers often recommend weight loss as an initial treatment since it can reduce the surrounding fat and reveal more of the penis.   

• Losing weight can improve erectile function overall. According to studies, losing just 10% of body weight has been shown to improve erectile function in those with obesity or overweight. A 2022 meta-analysis found that weight loss can improve erectile function, and researchers noted that it can be due to many factors like improved blood flow to the penis via better vascular health, reductions in inflammation, changes in mental health, and changes in testosterone levels. 

• Losing weight can increase testosterone levels. A 2024 review found that reductions in body mass index (BMI) in men with overweight or obesity are associated with increases in testosterone levels. Since testosterone plays  a major role in libido and erectile function, increasing your testosterone levels can make you feel like your erections are bigger and better than ever (even if your penis hasn’t actually changed in size). 

As we’ve covered, your penis size technically doesn’t change as a result of weight loss or basically anything else (other than surgery). But you might be able to see and measure more of your penis after weight loss, since the base of the penis will be more exposed when there’s less fat around the pubic area. 

Curious about your size? Here’s the most precise way to measure your member with a rigid ruler or tape measurer. 

1. Position the measuring instrument on top of your erect penis at the base (that’s where it attaches to the pubic bone). 

2. Press the end of the ruler into the pubic bone, past any hair or excess fat. 

3. Measure in a straight line from the base to the head  of your penis. 

Researchers found that measuring penises while they were flaccid generally resulted in underestimated sizes, so if you’re looking for the most accurate way to measure, we’d recommend measuring while erect. 

If you’re particularly curious about the change Ozempic might have on your penis size, consider measuring yourself before starting the medication and then checking in every month or so to see if your measurable length has changed. 

If you notice your penis seems longer after starting Ozempic, this is probably cause for celebration, not concern. As we’ve discussed, it’s almost certainly because of fat loss around the area, which is un-burying the base of your penis, making it look and feel longer. 

However, other changes to your penis might necessitate a consultation with a healthcare provider. Dr. Houman notes that you’ll want to seek medical evaluation if you notice any of the following. 

• A new lump or firmness in the testicle, which he says could signal a need to rule out testicular cancer. 

• Sudden shrinkage or atrophy of the testicles, which Dr. Houman says could indicate low testosterone or varicocele.

• Penile curvature or painful erections, which Dr. Houman says can possibly point to Peyronie’s disease.

• Ongoing difficulty achieving or maintaining erections. Erectile dysfunction (ED) can have many different causes, and there are plenty of treatments available. A healthcare provider can help you find the best treatment option for you. 

“When in doubt, get checked,” Dr. Houman says. “Men often delay care for sensitive issues, but early evaluation leads to better outcomes.”

No, Ozempic can’t actually increase the length or girth of your penis. But it can certainly make it appear larger. Fat and skin around the abdominal area can make the penis appear shorter, so losing weight will “uncover” more of the penis and make it look bigger. 

Research on Ozempic and erectile function is still in the early stages, but initial reports do indicate Ozempic can cause erectile dysfunction in rare cases. 

In one study, researchers found that people without diabetes who took semaglutide (the active ingredient in Ozempic and Wegovy) had a higher risk of being diagnosed with ED than those who took a placebo. But it’s worth noting that ED was still found to be a rare occurrence overall, with less than 2% of the people in the study developing this condition. 

Dr. Houman confirms that it’s not common, but it is possible for Ozempic to cause ED. He says that since Ozempic works by slowing gastric emptying and reducing appetite, this can lead to nutrient deficiencies or fatigue that may indirectly affect sexual function. As he puts it, in these rare cases, erectile dysfunction or reduced libido isn’t a direct drug effect but rather an effect of rapid weight loss or changes in parameters such as blood pressure. “For most men, improved weight and metabolic health actually improves erections,” he says.

Ozempic is frequently hailed as a miracle drug, but it won’t literally add inches to your penis. Losing weight around your midsection with the help of Ozempic can make your penis look and feel larger, though, so in that sense, Ozempic penis is a legit thing. 

• Your penis looks shorter when it’s surrounded by fat. Excess fat in the pubic area can conceal the base of the penis, making it appear shorter. This is called buried penis, and weight loss is one of the recommended treatments. 

• Losing weight with Ozempic or through other means can reduce this fat, which in turn can make your penis look and feel larger. You also might notice better erections after weight loss, since weight loss has been associated with improvements in erectile function, especially over time. 

• For the most part, your penis doesn’t grow naturally after you’ve gone through puberty. But certain changes to your penis and testicles — like a new curvature, a sudden firmness, or unexplained shrinkage — should be checked out by a healthcare provider.
