The History of Mission Abortion

Miffer-Prestone and Misoprostol are two drugs that block progesterone, which makes the uterus a hospitable place for an abortion to occur. The French were actually the ones that worked on Miffa-Prostone, R-U-486,. That's the one that blocks the progesterone and stops the pregnancy from progressing. It kind of started in Brazil because it doesn't make sense, but abortion is illegal there.
