>There are liars the world over. I don't think that is necessarily a trait that is just for men. I've know quite a few guys in high school that had unprotected sex because their girlfriend was on the pill end up with a baby because that is the way she thought she could keep him forever.

A friend's x-girlfriend got pregnant because she poked a hole in the condom without him knowing. If you are male and don't want to have kids, make sure you use your own condoms. Woman has many more options to avoid pregnancy, man has one shot with the condom (AFAIK vasectomy can be permanent).

I think this type of birth control has the potential of lowering paternity fraud since man will know the child is not his. It also reduces unwanted pregnancy when woman poke hole in condom or other condom issues.

This birth control for man is great news and I hope to see more male birth control options in the future.
