Because dads don't always think like moms.
As a guy, we warn you about one key thing that should be a pact between you and your wife. Neither of you should ever tell anyone who’s “fault” it is that you’re having trouble getting pregnant (if you even want to share that with others). Of course, if you’re the “let it all hang out” types, this advice doesn’t apply. However, if your wife, or even you, shares the secret, you can guarantee that this one will make the rounds in warp speed in a whisper campaign about your fertility. Sure, it’s not tied to your virility, but it is gossip that most men especially, would rather nip in the bud. And, the only way to do that, is to not tell anyone, including sisters, brothers, and especially mothers-in-laws.
