Interesting facts about men, women, and those tiny swimmers…

Special thanks to our gal-pal CJ who shared this interesting article

she found on the internet.

For those of you who read "Sperm Wars" or "The Selfish Gene" and
want to know more about the evolutionary psychology of our
species….

The more a woman has sex with her partner, the more committed she
becomes, and the less attracted she is to other men — at least in the
short-term. I blogged about this study several weeks ago and offered
explanations both hormonal and psychological. But another theory came to
my attention today in the form of a study on fruit flies.

For decades, scientists have known that female Drosophila refuse sex for
a period of time after they come into contact with seminal fluid. This
may give a reproductive edge to the first male with whom a female has
sex. A study led by Geoffrey Findlay at the University of Washington has
finally shed some light on the phenomenon. Turns out there are proteins
in seminal fluid, many of which transfer to the female’s system after
sex.

Some of these proteins are warrior-like — they fight the sperm of
rival males. Other proteins are like hypnotists — by affecting the
female’s hormones, they dampen her interest in having sex with other
males. Somewhat disturbingly, the more semen a female is exposed to, the
more influence the male has over her reproductive tract and her mating
behavior. Semen, it seems, has mind control properties.

So what does this mean for humans?
