Is it true that gaining weight can affect your penis size? Would this have anything to do with the hormonal changes associated with gaining weight?? Are there any studies that have identified the correct conversion factor of pounds of fat to inches of penis? Thanks. ---

It might cause an inverse relative size appearance, if nothing else, but I don’t think that putting on the pounds will make Willy grow. From what I recall of anatomy, there’s very little fat in that particular body part (at least for humans). ---

Actually, I recall a study that indicated there is an inverse relationship between size and size. Fat poundage accumulates everywhere, including at the base of your pride and joy. I recall that it was something like you lose 1/8th inch per 15 pounds of fat. Be all you can be. Starve. ---

Thanks. I was thinking that it is probably an inverse relationship, but I wasn’t exactly sure of that. However, I did find this- [http://www.lef.org/magazine/mag2003/may2003\_cover\_test\_02.html](http://www.lef.org/magazine/mag2003/may2003_cover_test_02.html) “_The result is one of the most common findings of researchers studying the relationship between testosterone and obesity: obese men have low levels of testosterone and extraordinarily high levels of estrogen._” ---

I love the idea of being able to pigout at McDonalds and pack all them pounds into my dick. hahaha ---

Actually, the exact opposite of that will happen. ---

I have heard that since the base of the penis is attached to bone any fat you accumulate around that area will reduce the length that is outside the body. I have no time to look for a site now though and I don’t remember where I heard this. ---

Apparently, liposuction of the suprapubic fat pad to reveal more of the penis is common in penile enhancement surgery. ---

You just have a sort of concave depression surrounding the penis. Like a flag in a putting green. ---

I don’t have a cite either, **Anachronism** , and I can’t tell you whether your physiology lesson is correct. But ask any obese guy, and if he’s honest, he’ll say that the end result is true: less of the penis sticks out of the body the fatter one gets. ---

Testicular atrophy has been associated with the use of steroids, so if you’re planning on gaining muscle mass through steroid use you may be in for shrinking nuts as well (“bitch tits,” too). ---

Okay, an 1/8 inch gain for every 15 pounds. I have to lose about 200 pounds to be anywhere close to a normal weight range, so I can reasonably expect to have a 19" penis by the time I’m done? Woohoo! Size queens, unite! My phone number is… ---

Some don’t aromatize (convert to estrogen), and therefore don’t have that problem. ---

Of course, how many of us wouldn’t like an extra inch and a half? Don’t answer that! ---

D’oh! I forgot that it was 1/8 inches, not straight (so to speak) inches… Oh, well. I can still just tell guys that it just \looks\ that small because of the weight, right? 😃 ---

Personal experience here but I’ve lost 36lbs since mid-February and both myself and Mrs.MeanJoe are quite pleased with the _ahem_ unveiling of Joe Jr. I never realized I’d lost so much… welcome back friend. _one hand hug_ 😃 MeanJoe
