question: My husband got a vasectomy a year and a half ago. 6 months ago he pointed out that he had a lump in his balls but wont see a doctor because he says it doesn t hurt so there is no reason to. I have done research and think it may be a sperm granuloma, I was feeling around down there and it also feels like on one side the tubes are connected to the lump. What are the chances he may be fertile again? And if it is possible what are the chances of pregnancy with only one side connected?
