Does Ozempic make your penis bigger? Weight-loss can expose more of the shaft, but the length stays the same.
The myth that Ozempic makes the penis bigger began after social-media posts claiming up to 4 cm of “growth.”
What really happens is that abdominal or pubic fat can hide part of the shaft, making the penis look shorter. When weight-loss occurs, that fat shrinks and the penis becomes more visible, giving a false impression of increased size.

So, does Ozempic enlarge the penis?
No—Ozempic does not enlarge the penis.
Dr Paulo notes there is no scientific evidence that Ozempic changes penis size.
The belief spread after Reddit discussions, where the term “Ozempic penis” emerged, later reported by this New York Post article.
Some users claimed measurable gains, but these anecdotes likely reflect greater shaft exposure—not true growth. Ozempic may also contribute to erectile-dysfunction risk in obese, non-diabetic men by lowering testosterone.

The role of fat in penis perception
According to Dr Paulo, the idea that losing weight with Ozempic makes the penis bigger is an optical illusion. Excess pubic fat can bury the base of the shaft, making it appear shorter.
When body-fat decreases—even around the pubic mound—the full length becomes visible again, correcting that illusion.
If residual fat or loose skin persists over the “mons pubis,” a surgeon may consider liposuction after individual assessment to improve exposure.
Can penis size actually be increased?
Approaches such as graft enlargement or suspensory-ligament surgery are reserved for specific cases and always require personalized medical evaluation. Minimally invasive options, like hyaluronic-acid or fat graft fillers, may also be discussed when anatomically appropriate and expectations are realistic.
