How the **** is this medically possible
The human body is an amazing thing.
The buddy of a coworker had the proverbial "bullets taken out of the chamber" after he and his wife were done having kids. The Doc told him once his samples came back empty in a few months, he should still get checked every couple of years to make sure his lines didn't regrow or reattach on their own as it's very rare, but can happen.
About three years go by, his wife gets pregnant. They almost get divorced because of course he's snipped and he's convinced she's fooling around on him (who wouldn't!). Bear in mind, he listened to other buddies of his that had been snipped who told him not to bother with the periodic samples because its nearly impossible to be fertile again and they were shooting blanks for years. So, he listened to their advice instead
.
Anyways, his wife pleads for him to go in and submit a sample as she's saying she's a faithful wife. He agrees to submit one but tells her if his sample is showing clean, he's walking out. Be damned if his lines didn't find each other or regrow and he became fertile again as his sample had plenty of swimmers in it.
