Plan B and IUDs Do Not Cause Abortions, I Promise


  • Hobby Lobby and many other people believe that IUDs and emergency contraception cause abortions. This is factually inaccurate.
  • Emergency contraception is a higher concentrated dose of what is already in regular hormonal birth control.
  • EC mainly prevents ovulation. It can also prevent implantation of a fertilized egg onto the uterus, but that’s not its primary mechanism.
  • Though it is theoretically possible for emergency contraceptives to prevent implantation, there is zero scientific evidence that it actually does this.
  • The same is true of IUDs.
  • The fact of the matter is that if all forms of hormonal birth control were available OTC without a pill, we wouldn’t have this problem.

Gina’s notes:

I rarely have anything to add to Cathy’s awesome stuff, but I will make one slight tweak.

The definition of an abortion is the termination of pregnancy. Abortion requires pregnancy. Pregnancy = fertilized egg + implantation on uterus. Plan B most often either delays ovulation or prevents an egg from being fertilized. In less common cases, it can prevent a fertilized egg from implanting into the uterus, but that is not an abortion. Implanting onto the uterus is required to be pregnant, and, therefore, preventing it from doing so is not abortion.

Now, where folks CAN disagree is whether or not keeping a fertilized egg from implanting in the uterus is ethically permissible. That is a matter of opinion. Whether or not Plan B causes abortions is a matter of fact, not opinion, and really can’t be reasonably disagreed upon.
