Mason Newman said he was prescribed Mounjaro, a medication commonly used to treat diabetes, which can also reduce appetite and is sometimes used alongside diet and exercise to support weight loss.
Mason explained that he lost 12 stone while taking the drug, and he said the changes he saw in his body went far beyond the number on the scale.
After going through all of that, he claimed Mounjaro finally helped him get results that stuck, but he also said something else happened that he didn’t expect at all.
According to Mason, the medication and weight loss journey also seemed to add three inches to his penis.

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.”
So what could explain why he felt like his penis had “grown” after losing weight?
In reality, it’s not that the body suddenly creates new length, but weight loss can mean more of the penis becomes visible if fat around the pubic area reduces.
Even so, Mason said he’s concerned about what could happen if he stops taking the medication and doesn’t have a solid routine in place to maintain his weight.
“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 the Chief of Reproductive and Sexual Medicine at Yale School of Medicine, and he has spoken about how weight changes can affect how prominent the penis appears.
Even with that said, Dr Honig noted that if someone experiences an unexplained change in sexual function, it’s best to speak with a medical professional so it can be checked properly.
