Oral sex can lower your blood pressure
According to a 2003 study published in the American Journal of Obstetrics & Gynecology, swallowing semen on a regular basis can lower your blood pressure. Women who swallow their male mate’s sperm during oral sex often have a much lower risk of getting preeclampsia — a complication during pregnancy that results in super-high blood pressure. So semen is helpful in making and birthing a baby.
It lowers the risk of prostate cancer (when expelled)
So this last one’s not so much a health benefit of semen, but rather the act of semen is released. According to a 2004 study in The Journal of the American Medical Association, “high ejaculation frequency was related to decreased risk of total prostate cancer.” This means that whether you do it alone or with a friend, if you’re ejaculating regularly, you’re lowering your chances of getting prostate cancer later in life. Suddenly the term “release your demons” takes on new meaning.
It could be the next all-natural fire extinguisher
You read that right. A 2013 study in Polymer suggests DNA in semen could be used to create flame-retardant materials. Right now, they’re looking specifically at DNA from herring sperm cells and finding that it converts to a “ceramic-like material when exposed to extreme heat.”
The science behind it is a little intense, but simply put, the components found in the DNA could be an environmentally friendly way to protect fabric from flame. While this sounds awesome, I wouldn’t go attempting the human fire extinguisher just yet.
