My cousin did that. He got snipped 15+ years age. Then he got remarried to a younger woman. She so wanted a child. But after a bring fixed there was no way. So the dr's vent in a were able to find one live sperm in one of his seminal vessels. they retrieved it, took on of his wife's eggs, fertilized it, after a few days, since it was viable they transplanted it back into her uturus. They have the cutest 3 yr old boy. No problems whatsoever. Goodluck
