Cougars Get Pregnancy Warning

A stubbornly high rate of unplanned and unwanted pregnancies among women over 35 has forced British authorities to launch a campaign to remind women of a certain age that unprotected sex can cause pregnancy. Officials behind the "Conceivable?" campaign say that warnings on fertility waning with age have led too many women to wrongly assume that they're too old to get pregnant.

The head of Britain's Family Planning Association warns that women should realize that a single night of unprotected sex in one's late '30s, '40s, or even '50s can lead to pregnancy. "Our helpline receives calls from such women, shocked this has happened to them," she tells the BBC. "They thought their age would protect them from becoming pregnant." (More family planning stories.)
