Chances of Pregnancy with Withdrawal Method

Dear Ask The Doctor: Me and my boyfriend have alot of sex we dont use condoms or any form of protection he just pulls out when he feels like he is about to cum.. what is the chance i could get pregnant?

Dear Kaley: Unfortunately the chances are pretty high.  When using the withdrawal method over the long term, the effectiveness rate of pregnancy prevention is near 50%.

This means that over the long term, 1 out of every 2 couples will experience an unwanted pregnancy.
