Researchers Discover The Powerful Physiological Effects Of Semen On Women’s Bodies, Brains & DNA
In scientific terms, semen is what’s known as a “master regulator”. Scientists have discovered how seminal fluid (which makes up approx. 70% of semen’s composition) has enormous physiological impacts on the female body and brain, including, among other things: the ability to activate genes, trigger changes in the uterus, reduce levels of depression in women, make women sleepy after sex, strengthen the emotional bond with their partner, and more.
The wide-ranging influence of semen on female physiology is “all about maximising the chances of the male reproducing,” says Sarah Robertson of the University of Adelaide in Australia. Further research conducted by a team led by Tracey Chapman of the University of East Anglia in Norwich, UK, has also found that males produce more seminal proteins when in the presence of rivals.
The discoveries were presented at the Society for Molecular Biology and Evolution conference in Vienna last week. The component of the research which found that semen significantly reduces levels of depression in women gained much attention at the conference. “If that effect is real, depression in some people might be treatable with artificial-semen suppositories,” writes Michael Le Page of New Scientist. “Gordon Gallup of the State University of New York at Albany, who carried out the study, says a PhD student of his has replicated the finding in a survey of 1000 women, but the results were never published.”
The proteins of seminal fluid can quickly enter the blood stream and reach the brain, having an almost instantaneous effect on hormone regulation, mood, gene activation, immune system regulation, ovulation, uterus receptivity to sperm and embryo, and even the activity and growth within the embryo itself. The take home message clearly being that semen’s effect on female physiology goes far beyond reproduction alone.
