Time November 19, 2007 - 5:00am Link New evidence for female control in reproduction Description Adding another layer of competition to the mating game, scientists are reporting possible biochemical proof that the reproductive system of female mammals can "sense" the presence of sperm and react to it by changing the uterine environment. This can be the molecular mechanism behind promiscuous female choice, in which females that have mated with several partners play a role in determining which sperm fertilizes their egg.
