Do all or any of you believe the large penis comes from the dad's side of the family, mom's side or both? Have any guys at a talk from their dad about the family jewels?
Actually, penis size is determined in utero, and is dependent upon the level of testosterone in the mother's system while pregnant. The levels of testosterone tend to increase in subsequent pregnancies while carrying boys, thus the chances of a younger brother being larger than an older brother are greater than the opposite.
studies also show higher levels of in utero testosterone also increase the odds of a male being gay. (This is not the case with females). Hence if you are the youngest of 6 brothers, you hava a higer chance of both having a larger penis, and of being gay.

That's ! Do you have a good source for this? I'd like to read up on this. It explains some trends I've seen with my extended family. Thanks!
