Evolution of the female orgasm

Aspasia Lecture by Elisabeth A. The female orgasm in humans presents an evolutionary puzzle. The male orgasm has a straightforward evolutionary function: it makes males want to have sex more often, which in turn makes them more likely to have offspring. But how to account for female orgasm, when nearly three-quarters of women don't always reach orgasm during sexual intercourse? Moreover, if female orgasm is not associated with any increase in fertility or reproductive success, then what exactly is its function, if any? Several evolutionary explanations for the occurrence of female orgasm among humans have been proposed.

They are often associated with other involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations. Human orgasms usually result from physical sexual stimulation of the penis in males typically accompanying ejaculation and of the clitoris in females. The health effects surrounding the human orgasm are diverse. There are many physiological responses during sexual activity, including a relaxed state created by prolactin, as well as changes in the central nervous system such as a temporary decrease in the metabolic activity of large parts of the cerebral cortex while there is no change or increased metabolic activity in the limbic i. In a clinical context, orgasm is usually defined strictly by the muscular contractions involved during sexual activity, along with the characteristic patterns of change in heart rate, blood pressure, and often respiration rate and depth. There is some debate whether certain types of sexual sensations should be accurately classified as orgasms, including female orgasms caused by G-spot stimulation alone, and the demonstration of extended or continuous orgasms lasting several minutes or even an hour.

The Evolutionary Origin of Female Orgasm

Have scientists solved the mystery of the female orgasm? As a team of researchers pointed out, during intercourse the male orgasm serves an obvious reproductive function: Without it, ejaculation can't happen. But the reproductive role of female orgasm has been much less clear, because ovulation in humans occurs whether a woman has recently had an orgasm or not. So the very existence of the female orgasm in women has long been a physiological mystery. But now U.
