Abstract

The common problem of premature ejaculation is explained in terms of evolutionary adaptation. Based on findings from primate behaviors, I hypothesize that those protohominids who were rapid ejaculators (perhaps with a highly sensitive glans) were less likely to be repelled by the females and/or attacked by other sexually aroused males. As a result, they had more opportunities to copulate and to impregnate. Thus, the likelihood that speedy ejaculation would be represented in the succeeding generations was progressively increased. Hence, male Homo sapiens today are over-represented with individuals possessing this once superior trait. I further argue that premature ejaculation has become dysfunctional only in recent times as a consequence of the lag between biological and social changes.
