In the ongoing battle between a lot of men on how women should be dealing with their bodies, wording is everything.

A common belief, on both sides of the political spectrum, is that morning-after pills prevent pregnancy after sex by stopping the fertilized egg from implanting in the uterus. Some believe that as long as the egg is fertilized, stopping its implantation constitutes an abortion. However, in a recent New York Times investigative report on Plan B, the pill that has been on the American market the longest, scientists have found that the way the public believes the pill works may be based on outdated information.

According to recent studies, Plan B actually delays ovulation and  blocks the egg from entering the uterus, thus never allowing it to get fertilized in the first place. If the egg is never fertilized then Plan B does not technically fit the Pro-Life definition of an abortion inducing drug, and is not really an “abortive pill” as Mitt Romney has recently called it.

However other morning after pills, like Ella, may effect fertilized eggs. Tests are still being done.

The problem is that the description of how these pills work as labeled on the packaging and expressed to the public, is pretty vague. Morning after pills have been on the market for over ten years and scientists are only now figuring out, or revealing, the specifics of how they function.

Whatever your perspective, it would be nice to know how drugs like these work, so we could all make an informed decision, instead of waiting on science to prove – and disprove – itself over and over again.
