My boyfriend has a vasectomy done almost 2 years ago now, I had recently found out that I was pregnant and he decided to have his sperm tested again and the test came back with active sperm... will he be able to have another vasectomy done? are there additional risk involved with having it done a second time? and is there still a chanche that the tubes will grow back together again?  Thank you for your time and help with these questions.
Hello Thank you for trusting Chat Doctor Vasectomies are very effective. Only about 2 out of every 1,000 women get pregnant in the first year after their partner had the procedure done. Less than 1 percent of vasectomies need to be repeated. If sperm came positive means your boyfriend have to meet the doctor. He will guide your boyfriend accordingly.
