Aww, making up cringe stories, as brainless snowflakes must do so frequently.
Let Spartan point out the misinformation and shed truth on the subject for those who might consume soy, even as I never do.
Can soy really cause gynecomastia? Short answer, no. Only uneducated, brainless twits would ever think so. There have been extremely rare cases of it in some who consumed processed soy in huge amounts but even those rare cases were resolved by a change in diet.
The really brain dead who refer to such terms as "soy boy" are really just ever showing their extreme ignorance and extremely low IQ. It is often noted to be just projection by very soft men w/feminine traits. Perhaps, MDB is mad here cause he doesn't understand why he, himself, has man boobs. It probably has less to do with phytoestrogens and a whole lot more to do with him being an out of shape fatass who eats too much processed foods while making ultra cringe posts.
