Male Semen: The Most Potent Antidepressant for Women Yet Discovered
Study author Gordon G. Gallup, Ph.D., a psychologist at the State University of New York in Albany, also found that women who routinely had intercourse without condoms became increasingly depressed as more time elapsed since their last sexual encounter. There was no such correlation for women whose partners regularly used condoms.Source
Gallup's survey of 293 college women also found that those who did not use condoms were most likely to initiate sex and to seek out new partners as soon as a relationship ended. "These women are more vulnerable to the rebound effect, which suggests that there is a chemical dependency," says Gallup.
Semen contains hormones including testosterone, estrogen, prolactin, luteinizing hormone and prostaglandins, and some of these are absorbed through the walls of the vagina and are known to elevate mood.
You must know that this is only the beginning. Combined with the knowledge that contraceptive pills reduce libido in both women and their partners, it is beginning to look as if the most popular birth control methods are not only protecting from pregnancy, but also protecting from other things considered very desirable.
This is a topic worth following more closely. My compassion demands it.
