See a doctor and see if you are producing sperm.



Other Reason for Pregnancy After A Vasectomy

Sometimes a vasectomy fails because the vas deferens has grown back together. This happens very rarely, but it can occur. It is thought that only one in every one thousand procedures that this happens. When it does happen, this is called recanalization. It is thought that the main reason why pregnancy occurs after a failed vasectomy is because there are tiny pieces of sperm debris along with scar tissue and white blood cells that enable the vas deferens to grow and the end result is that it reconnects to the area where the incision was made and it splits the vas deferens.
