A Woman’s Reproductive Tract Can Weed Out Unwanted Sperm
- blaser-waffle 6y agoHoly shit does that headline make it sound like an ugly quote about "shutting down legitimate rape". Actual points from the actual article: > A sperm's swimming motion, speed and viability are affected by the level of genetic compatibility between a female's cervical mucus and the male's sperm, found a new study that published Wednesday in the Proceedings of the Royal Society B journal. > A prior study by the same authors found the same thing occurred in a woman's follicular fluid. > Think of it as a chemical "sorting hat" -- dictated by a female's reproductive secretions -- that help sperm who are most likely to give her offspring a genetic boost in survival.
