If anti-abortion activists thought that redefining the laws of gravity would help their cause, they wouldn’t let a little scientific evidence get in their way. And the latest campaign is almost as far-fetched: A group called Personhood USA is trying to redefine when life begins. It starts “exactly at creation,” according to Keith Mason, president of Personhood USA. “It’s fertilization; it’s when the sperm meets the egg.” Mason wants laws to recognize every fertilized egg as an individual and complete human being.
Not that it matters to Mason, but the, um, facts aren’t exactly on his side. Medically, fertilization does not mark the beginning of pregnancy — because only about half of all fertilized eggs end in pregnancy. Medically, pregnancy begins once a fertilized egg implants in the uterus. But perhaps Mason doesn’t realize this, given that he probably thinks sex ed is for losers.
