Ahaha... I like this question.

No.. If you drink soy milk you will not develop gynecomastia. (man boobs). The only way a man can develop breast tissue is with estrogen hormones or an elevated testosterone level where some test is converted to the body with estrogen. You need *some* estrogen in your body, just not too much. In either case, soy milk does not contain these hormones to make this happen.

Enjoy your soy milk. So good tastes best... Try their vanilla, omega 3, and chocolate flavors..

Yeah I was wondering that too and I just couldnt see that possible. But I thought I would ask I dont want man boobs lol!!!! But thanks and never thought of it that way

The effects of soy could actaully help reduce estrogen levels by take over the natural male production and replacing with weaker "synthetic"(soy)so maybe reduce nipple and or chesticle(man boobs if you havent heard that term yet) size in men.?
