There was a letter to Carolyn Hax that was really close to this a few days ago... the letter writer's DH came to her and told her that he'd had a vasectomy while he was with his ex-FI. This was six months AFTER their wedding, and he knew she wanted kids. I felt so bad for her. That was waaaay too late. As for "upfront" I think that depends on what upfront means. "Hi, I'm Fred, I've had a vasectomy!" is a little too open. I think big (more private) things, such as STDs or major debt should be put out there after a few dates when it looks like things could be going somewhere, but no one is committed yet.
