ADAMROML: In regards to the question of correlation between male pattern baldness and penile endowment, I would have to say that there is very little, if any, empirical data that would suggest such a thing. As a corollary, consider the theory that men with small hands have small penises; both theories suggest that there are a bare minimum of genetic molds that human males can fit into.
I am a 27-year-old male, and like my father, started balding in my early twenties. I have a very thin frame and very small hands and features. I wear size 11 shoes. My penis is 1/8 of an inch shy of 8 inches, and 5 and 1/4 inches thick.
Does this suggest anything? Does it mean that anyone else who is an ectomorph and balding with small hands and big feet would naturally have a dick the same size as mine? While it is possible, it is still highly doubtful.
Whatever the case may be, and no matter what the question of correlation is, the answer will always be the same. Each and every human is so different on a genetic level that it would be highly improbable for any pattern to exist.
