BBC NEWS | Pill propelled into abortion debate: By Jill McGivering
BBC correspondent in Washington

The birth control pill revolutionised women's health - and grew to become one of the most popular forms of family planning. But it is now under attack from pro-life groups in the US.
A growing number of doctors and pharmacists are now refusing to dispense it, on the grounds that it is actually a form of abortion.
Pro-choice groups fear this new moral objection to the Pill could lead to more unplanned pregnancies, even more abortions.
A woman taking the Pill does not usually release eggs. But occasionally she might - and it is possible that egg could be fertilised.
The hormonal conditions created by the Pill mean, if that happened, the fertilised egg would not be implanted or survive.
Mainstream medicine does not define that as a pregnancy. But some of those strictly against abortion do.
Dr Cynthia Jones-Nosacek - a family doctor in Milwaukee - now refuses to prescribe the Pill. She opposes it on moral grounds, arguing it is a form of abortion.
'The contraceptive pill doesn't always prevent ovulation. As often as 30% of the time, ovulation may occur and if that happens, fertilisation may occur,' Dr Jones-Nosacek says.
'Then there are other mechanisms that can prevent that being from surviving. It's called a chemical abortion.' "
