You may have noticed a recent snippet in your daily rag loudly dictating that the female ability to orgasm could be genetically inherited. Read the fine print:
The discovery of a genetic basis for the ability of women to orgasm raises questions about its evolution. One theory is that it is a tool for mate selection, the idea being that males best able to bring females to orgasm are also the best males to help raise children. Another is that the female orgasm produces movements that increase sperm uptake, and therefore fertility.
But studies of other primates suggest otherwise. Female stump-tailed macaques have orgasms too - but mainly during female-female mountings, which hardly supports the fertility or mate-selection idea.
