A member asked:

Do testosterone levels relate to overall penis growth during puberty or just the speed of growth?

Penile size is: largely dependent on genetics, and not on specific testosterone levels. The onset of puberty for boys is quite variable, but once the testicles start to make testosterone, the speed of growth of the penis seems to be fairly consistent from boy to boy and takes about 3 years from onset of growth.
