Keeping in mind that little people die if the MAP is abortifacient, the burden of providing conclusive evidence is upon those who hold MAP up as a true “contraceptive”.
And they have yet to deliver on that.
If they had, Planned Parenthood’s website would do more than cite studies that “imply” that MAP works only by preventing ovulation. And the manufacturer would change their label. It’s preposterous to think that this is simply old information that they haven’t gotten around to updating.
I don’t know why it is so difficult to settle this question conclusively from a scientific standpoint. But the fact that neither the manufacturers nor the retail marketers of Plan B can bring themselves to state definitively that implantation is not prevented by Plan B is important. There must be some difficulty in clinically proving this, or they would have done it by now.
The label on the product carries a lot more weight than stuff posted on the internet.
So, in conclusion, you may have some evidence. But it does not appear to be conclusive. Which means, at least for now, that the MAP is still, officially, “potentially abortifacient”.
