Despite the controversial nature of the issue, the academy has issued a new statement, updating its 2001 position.
It's now recommending communities, educators, parents and doctors help make condoms more available to this age group.
In a statement published Monday in the group's journal Pediatrics, several doctors write that "abstinence is the most effective method of prevention."
But the doctors also say "young people should be prepared for the time when they will become sexually active."
The Centers for Disease Control and Prevention said teen pregnancy rates are declining in the U.S. and are at a record low, but the agency also says sexually transmitted infections are still a problem in this age range.
People between ages 15 and 24 account for half of the 20 million new cases every year.
