The female orgasm has been a topic of debate among evolutionary biologists (and among many other people as well, of course). Is it adaptive, or a by-product of the male orgasm?

A new study, published in Animal Behaviour, takes a look at the question. The authors argue that, if the female orgasm is an evolutionary by-product, similar genes would lie at the root of orgasmic function in both sexes. Consequentially, opposite-sex twins and siblings would share more similarities in their susceptibility to orgasm. read more
