Clinical Research - healthy sexuality linked to general health


Although many of the benefits reputed to come from sex are drawn from inconclusive studies, there are in fact, many positive health benefits have been substantiated by scientific research.

Depression in women - One study, conducted by psychiatrist Gordon Gallup of the State University of New York, Albany, found that females having unprotected sex were significantly less depressed than both sexually inactive females and females who had sex with protection — indicating a connection between exposure to semen and elevated mood in women. Gallup said some of the chemicals found in semen can be found in the female bloodstream after sex — having been absorbed through the vaginal epithelial tissue — within about an hour of intercourse.
His study, published in 2001, also found that depression scores went up as time after the sexual encounter increased, suggesting the possibility of a “semen-related withdrawal effect.”

Endometriosis - Another study, conducted at Yale University, fertility doctor Harvey Kliman, explored the effects of orgasm on endometriosis — a condition in which the uterine lining grows in other areas of the female body.

Kliman’s study found that women who had a high frequency of orgasm during menstruation— either through intercourse or masturbation — had the lowest instances of endometriosis. While orgasms ordinarily produce upwards contractions to suck semen inwards, during menstruation, orgasms instead intensify the outward motion of orgasmic contractions, thereby pushing debris out instead of pulling it in, he said.
Logan Levkoff, a sexologist who spoke at Yale on the female orgasm, said sex increases the production of DHEA, a natural steroid, and releases hormones that reduce stress, improve muscle pain and cramping.
