From what I have read, Semen contains prostaglandins that has the same properties as the gel they use in the first stage of induction. So, sex may help to ripen the cervix during the last few weeks of a pregnancy. But I guess if it's not really, it's not ready, there is only so much that will work, IYKWIM.

But really, it can't hurt right , I was told that having a big "O" can help things along as well. So I say go to it like bunnies, he he he Enjoy it......
