The functional significance of the human male foreskin is considered in evolutionary terms. It is postulated that there is a lifetime's reproductive advantage in delaying the age of first coitus, and hence of first childbirth, for some years after puberty, until the parents are better established as providers. Phimosis and preputial adhesions are common in human males because they have selective advantage, tending to impede and therefore delay the onset of sexual activity. The physical signs of female virginity have an analogous function, and have been selected for in the same way. This hypothesis also provides a consistent explanation for the worldwide tradition of circumcision and for the common practice of masturbation by human males.
