Morning-After Pills Don't Cause Abortion, Studies Say : Shots - Health News : NPRThe constant references to Plan B and ella as abortion-causing pills frustrates Susan Wood, a professor of health policy at George Washington University and a former assistant commissioner for women's health at the FDA.
"It is not only factually incorrect, it is downright misleading. These products are not abortifacients," she says. "And their only connection to abortion is that they can prevent the need for one."
That's not a universal medical opinion, however.
"It would be my preference that none of these products had any potential to cause abortion or post-fertilization effects that would be my preference but we don't know that," says Gene Rudd, senior vice president of the Christian Medical and Dental Associations and a practicing OB-GYN in Bristol, Tenn.
That's not really the case anymore.
For years, scientists knew the pills, particularly Plan B, were highly effective in preventing pregnancy after unprotected sex but weren't exactly sure how they managed that. "It wasn't really clear whether it worked before ovulation or after ovulation," says Wood.
Scientists did know the drug worked primarily by preventing ovulation. It stops an egg from being released from a woman's ovary and thus prevents any chance of fertilization and pregnancy. But they also thought the drug might make it more difficult for a fertilized egg to implant in a woman's uterus.
Technically, that's not an abortion, says Wood.
"We know that about half of fertilized eggs never stick around. They just pass out of the woman's body," she says. "An abortifacient is something that interrupts an established pregnancy."
But people like Rudd worry that even if what the drugs do is not technically abortion, it's still objectionable if it happens after fertilization.
But it turns out, at least when it comes to Plan B, there is now fairly definitive research that shows the only way it works is by preventing ovulation, and therefore, fertilization.
"We've learned a lot about how these drugs work," says Diana Blithe, a biochemist and contraceptive researcher at the National Institute of Child Health and Human Development. "I think it's time to revise our speculations about how things might work in view of data that show how things do work."
For example, says Blithe, a study published just last year led the International Federation of Gynecology and Obstetrics to declare that Plan B does not inhibit implantation. And some abortion opponents in the medical community are beginning to accept that conclusion.
But if the FDA says it isnt....wait...the FDA never says if it is an abortificiant or not so where are you getting this "translation"?
Funny how there isn't actually a study in there that actually backs up any claims made.
