NY Times: “A federal advisory panel voted unanimously Thursday that federal drug regulators should approve a medicine that could help prevent pregnancy if taken as late as five days after unprotected sex.It is a chemical relative to RU-486, the abortion pill, and some mystery remains over exactly how it works. That mystery spurred a fierce debate outside the committee over whether it should be considered an abortion drug…The dispute is whether the drug works by delaying ovulation (as the pill’s manufacturer claims) or by preventing a fertilized egg from implanting itself in the uterus (as anti-abortion advocates say).”
