In 2005 www.abc.net.au reported on a study about the effects of pornography on sperm***
“Looking at pornographic images of men and women together can increase the quality of a man’s sperm, a new study suggests. The effect is based on an evolutionary process observed in animals known as sperm competition.
Males ejaculate more sperm, or sperm of better quality, when the risk of sperm competition [the probability that a female will mate with more than one male] is high.
Research now shows that just looking at an image of another man in action is enough to register as a case of sperm competition, causing a compensatory adjustment in the viewer’s semen
I don’t know about my male readers but looking at this early photograph of Yul Brynner certainly increases my desire to check out the quality of freshly produced sperm. You know the drill…. bring your specimen in its original container to nursemyra’s Thursday morning clinic for a free personal evaluation……
