Researchers make progress in understanding traits and processes that influence fertilization success

Female promiscuity-something that occurs in a majority of species, including humans-results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm compete for fertilization of the female's eggs. In addition, the female has the opportunity to bias fertilization of her eggs in favor of one male's sperm over others.

Judge blocks new Wis. abortion law; Texas rallies draw thousands
