Well, I think I've seen it with my own eyes. I have 3 teen boys, all breastfed as babies. For one of them, him mom went nuts with soy milk right after his birth. (a screwy doctor suggested it) She drank crazy amounts of it. Sure enough, that boy clearly has boobs, and the others (same parents) do not.
