      I thought this diary had faded away.  The law is so extreme that it might consider preventing implantation as no more than just another way to kill an "unborn child," i.e. fertilized egg.   I have to think of a way to say what I mean without getting into  a discussion of how different chemicals work.

    •  You are incorrect. No postfertilization effects. (1+ / 0-)

      There is a substantial body of research demonstrating that levonorgestrel has no post-fertilization effects.

      Plan B and other hormonal birth control methods do not prevent implantation of a fertilized ovum (technically a blastocyst at implantation). They can only suppress ovulation.

      If they fail to suppress ovulation, they fail. Period. This is why they have such high failure rates and are a poor choice of primary birth control.

      That was once believed to be true, but it is now known that it will not prevent a fertilized egg from implanting. The FDA label states that it prevent ovulation and may prevent implantation. There was never any proof of the last part and we now have more studies that indicate that fertilized eggs will implant.

      Studies have not established that emergency contraceptive pills prevent fertilized eggs from implanting in the womb, leading scientists say. Rather, the pills delay ovulation, the release of eggs from ovaries that occurs before eggs are fertilized, and some pills also thicken cervical mucus so sperm have trouble swimming.

      It turns out that the politically charged debate over morning-after pills and abortion, a divisive issue in this election year, is probably rooted in outdated or incorrect scientific guesses about how the pills work. Because they block creation of fertilized eggs, they would not meet abortion opponents’ definition of abortion-inducing drugs. In contrast, RU-486, a medication prescribed for terminating pregnancies, destroys implanted embryos.

      The notion that morning-after pills prevent eggs from implanting stems from the Food and Drug Administration’s decision during the drug-approval process to mention that possibility on the label — despite lack of scientific proof, scientists say, and objections by the manufacturer of Plan B, the pill on the market the longest. Leading scientists say studies since then provide strong evidence that Plan B does not prevent implantation, and no proof that a newer type of pill, Ella, does. Some abortion opponents said they remain unconvinced.
