Abortion is legal in the United States in part because, as a 2007 World Health Organization study shows, abortion bans don't actually prevent abortions. Women can terminate their pregnancies whether it's legal or not; all the government can do is make the procedure more dangerous by banning medical supervision.
When countries go the extra mile and try to ban women from altering their own bodily functions to prevent a pregnancy, the results are Orwellian--as we see in much of Latin America, where forensic vagina specialists investigate hospitalized women for suspicious-looking miscarriages.
Or Utah or Kentucky, where proposed legislation would criminalize miscarriages in cases where prosecutors do not feel that survivors have done enough to protect their pregnancies. The situation in Utah is particularly dire: the bill has passed both chambers of the legislature, and currently awaits a signature or veto by the governor.
Women's rights groups, including National Advocates for Pregnant Women (NAPW), are working to fight bills that violate the civil liberties of pregnant women. But as long as conservative legislators see embryos and fetuses as citizens, and pregnant women as property of the state, pregnancy regulation is likely to remain an integral part of the pro-life movement.
