great fodder for jokes about boys… from seed magazine’s i can’t believe it’s science
Scent of a Woman
A new study published in the journal Analytical Chemistry shows that sperm have a sense of smell. Further, it’s so sophisticate that even an ovarian scent that’s diluted 100,000 times will cause the little gametes to turn tail and swim in its direction. The study’s authors note that sperm have olfactory receptor proteins—much like those in our noses—which reside over their outer membranes. The researchers used mouse sperm for their study, but they are confident their results apply to man-sperm as well. Apparently, sperm does not hold much of a species bias, as sperm from one mammal will respond to ovarian chemicals from another.
