I just thought it was strange since it's never been that hard before. Some years ago I got a guy pregnant just after the second alien abduction, and last summer after the fifth. My only explaination for this was either the loyal trait or that the chance might had been lowered even more in a recent patch.
25% isn't that low I just think it should have worked in any of the 20+ tries I did. I saved the game just when he was about to be abducted and replayed from there each time it didn't work, and that's the same thing I've done previously when it did work.
