I have 3 kids, all healthy. I mean, when she went off the pill for each one, it took in a week. Maybe one night. (Or day) But it was quick. But that was over 34 years ago for the youngest one. Maybe all the estrogen in the water and food is killing sperm?
“But that was over 34 years ago”
Maybe you should do some testing with your wife just to be you are still OK.
