If this holds up in future experiments, Lloyd says, it would establish that a woman's ability to have an orgasm during sex rests on an anatomical trait that likely varies with exposure to male sex hormones in the womb. In analysis of the Bonaparte data, the researchers first had to reframe the question. But that isn't the case, Lloyd explained, citing one study of more than 8, women in which the researchers found no correlation between female orgasm and the number of her offspring.

Only in the last chapter do we get a discussion of how bias led to these models and what the role of bias should be in science--in short, the actual philosophy. The data on female orgasm is shockingly flimsy, and Lloyd nicely shows how even carefully conceived experiments such as for testing the upsuck theories present a host of problems. You know, perhaps there should be more debate about this. About 75 percent of all women never reach orgasm from intercourse alone -- that is without the extra help of sex toys, hands or tongue. But perhaps more importantly for the popular media, her theses are very easy to state in layman's terms. I cannot recommend this book enough for anyone interested in philosophy of science.
I believe that her book settles the argument, and the implications for future male-female social relationships are profound. Harvard University Press, , Nature , pp. The clitoris is the homologue of the penis - it is the same organ, endowed with the same anatomical organization and capacity of response. Simply put, most women do not have orgasms through "unassisted" intercourse, and most women can and do have orgasms without any male involvement. Widow of Pulse nightclub shooter acquitted on all counts. Lloyd's study of 80 years of previous sex research in her book, "The Case of the Female Orgasm," debunked theories that there is an evolutionary reason for the female orgasm.

Female Orgasm: Serving an Evolutionary Function? | HuffPost
To further complicate matters, there remains a lack of complete agreement on what constitutes female orgasm Meston, et al. The mate-choice hypothesis states that female orgasm has evolved to function in mate selection in order to better attract mates who will be invested long-term or to select higher quality sperm for higher quality offspring. The byproduct hypothesis states that female orgasm doesn't have a direct evolutionary function; rather, women experience orgasm because of men's adaptation to it. In either case, a series of changes involving the hormones oxytocin and prolactin are triggered that cause the egg to mature and migrate. How to contact the news team. In males, orgasm is invariably required for ejaculation and transfer of sperm, researchers noted in a piece published recently in the Journal of Experimental Zoology. Possibly variation in prenatal androgens produces other genital changes, in addition to rostral migration of the genital tubercle, that influence the type of stimulation a women requires for reaching orgasm.
