It might also explain why most women's erogenous zone is the clitoris, instead of the vagina, Fleischman says. What we're interested in here is the "pCv" the coefficient of variation. The clitoris is also analogous in function and development to the glans "head" and upper shaft of the penis, rather than to the entire thing. So then, it would not be subject to natural selection. I think a lot of the people researching it also agree, which is why people have looked for evidence of a role for female orgasm is things like bonding.
Where does the female orgasm come from? Scientists think they know
The tenuous link between orgasm and intercourse in women has led other theorists, including Donald Symons, to conclude that the female climax is more accident than adaptation. Her presentation is informative, titillating and to some perhaps scandalous. Masters and Johnson established the physical parameters of orgasm in their landmark book, Human Sexual Response. Continued research in this field will only serve to better our understanding of this once-taboo topic. Just as sperm counts increase, men who've spent more time apart from their partner report she is more attractive, think other men find her more attractive, and want to have sex even sooner.
Why women have orgasms: an evolutionary analysis. - PubMed - NCBI
Making the modern world: By Karen Wright Monday, June 01, Or maybe put it another way, the evolutionary "mystery" of contemporary women's orgasms probably won't be solved without including the contemporary men's orgasms in the problem set. The lust for copulation originates from the need to reproduce. Why do you think the female orgasm has caused so much discussion among scientists? It makes perfect sense that something as fundamental as orgasm would be present in both sexes -- it would take quite some chromosomal juggling to have it be entirely missing in one.
Because most females must gestate and raise their offspring, repeated bouts of lovemaking yield diminishing returns where conception is concerned and interfere considerably with the duties of motherhood. Why do men have nipples? Mihaela Pavlicev, evolutionary biologist and professor at Cincinnati Children's Hospital Medical Centre, also questions Fleischman's argument. The male orgasm positively reinforces ejaculation and therefore encourages males to propagate the species, Lloyd says. Lloyd, a philosopher at Indiana University argues.
