An orgasm in the human female is a variable, transient peak sensation of intense pleasure, creating an altered state of consciousness, usually with an initiation accompanied by involuntary, rhythmic contractions of the pelvic striated circumvaginal musculature, often with concomitant uterine and anal contractions, and myotonia that resolves the sexually induced vasocongestion and myotonia, generally with an induction of well-being and contentment.

In a paper published today, they argue that female orgasm is an evolutionary holdover from an ancient system, seen in some other mammals, in which intercourse stimulated important hormonal surges that drive ovulation.
