A man has shared how taking medication to lose weight resulted in an unexpected side effect on one particular part of his body.

Mason Newman was prescribed Mounjaro, a drug used in treating diabetes, which also suppresses appetite and can be combined with diet and exercise to assist with weight loss.

Mason revealed that he lost 12 stone after taking the medication, but this was not the only effect that the medication had on his body.

The 28-year-old claimed that he went from an XXXL to an S, and said to The Sun that before going on a GLP-1 drug, he had tried practically every diet that's out there in an attempt to lose weight.

But what was the unexpected extra effect that the GLP-1 Mounjaro had on Mason's body?

This was that it allegedly added three inches to Mason's penis.

Given that the average penis size in the US is around 5.1 inches, that's a pretty substantial increase.

Mason said: “I tried the keto diet, water fasting. I tried juices. I tried eating nothing but two chicken breasts a day and nothing else. That lasted three weeks and was more of a mental challenge than anything. I couldn’t stick to them.”

But how exactly did his penis 'grow' after the weight loss?

“The first thing I noticed was I grew three inches on my penis,” he said. “Because when the fat goes you actually do see more of yourself.”

So, it's not 'grown' strictly speaking, but losing the weight meant that more of his appendage was visible and not being concealed by fat.

But Mason is worried about the effect if he stops taking the medication.

He said: “I put a stone back on, and the change in my mental health was crazy. I started getting anxiety and panic attacks again, so I went back on.

“If I come off it without building healthy eating habits, I’d put all the weight back on. I’m stuck, but I suppose there are worse things to be stuck on."

Dr. Stanton Honig is Chief of Reproductive and Sexual Medicine at Yale School of Medicine.

The doctor explained that fat reduction is a key factor in someone's penis becoming more prominent, but it doesn't stop there, as GLP-1 drugs can improve cardiovascular health, which could also help if someone is experiencing erectile dysfunction.

Nonetheless, Dr Honig added that if someone has an unexplained change in their sexual function, then they should speak to a medical professional.

UNILAD has approached Eli Lilly, the manufacturer of Mounjaro, for comment.
