The Food and Drug Administration was considering lowering the age for those who can buy the Plan B emergency contraceptive over the counter, but in a surprise move today, Secretary of Health and Human Services Kathleen Sebelius decided to keep the age restriction in place.

Right now, teens under the age of 17 need a doctor's prescription to get the Plan B morning-after pill. In a last-minute decision, Sebelius overruled her experts, saying that drugmaker Teva Pharmaceuticals didn't prove young girls could understand how to use the product without help.

Groups such as the American Family Association are applauding the decision.

"I think that decision defends basic parental rights to know that your child is engaging in sexual activity that can result in a pregnancy," says Frank Russo, of the American Family Association.

However, Joann Smith, of Planned Parenthood, argues that some teens can't or won't talk to their parents about sex.

"Would we rather our teenagers have a baby rather than have access to emergency contraception without parental consent?" she asks.
