Re: Vasectomy Failure?
Correct me if I'm wrong, gentlemen, but I was always under the impression that the testicles will continue to produce sperm after a vasectomy. What changes with a vasectomy is only that the tube that the sperm travels through is no longer connected, so the sperm never makes it to the seminal fluid that's ejaculated, but sperm is still being made.
If you are concerned about your sample, get them a good one, and have them check it. (Just curious, why would you give them a sample of pre-***? They have to test your ejaculate, not pre-ejaculate.)
