New research is revealing that one in three women were able to have a baby the first time they tried in vitro fertilization. And, if success doesn't come the first round, chances go up with a second try to nearly one in two.
But undergoing a third cycle boosted success rates very little and leveled off with subsequent attempts.
Scientists involved in the study say, if you haven't gotten pregnant by the third try, chances are slim to continue.
The new study presented at a meeting for the American Society for Reproductive Medicine is the first to examine IVF rates nationally.
Advocates who help infertile couples say this information will help them in their decision making.
