Visual erotica and sperm quality


Study reveals that pornography can increase sperm quality

According to a recent study, viewing images of men and women having sex can have a positive effect on sperm quality. The study measured motility and overall health of sperm provided by donors for in vitro fertilization procedures, and found that the sperm from the men who were watching visual erotica at the time of the donation were healthier than the sperm from men who weren’t watching visual erotica. One proposed explanation lies in evolutionary biology -- a sort of perceived "sperm competition" between the man providing the sample and the man in the movie.
