I once read that penis and testicle size is highly correlated with the amount of endogenous testosterone the fetus receives from its mother - i.e. a mother with higher levels of testosterone will produce a child with larger male genitals.
So I guess that leads me to ask what would make a woman have higher levels of testosterone? Stressful environment? Fast life strategy?
