There are three primary ways a pregnancy can occur after a vasectomy: 1  Having sex without contraception before the manâs sperm count is confirmed to be zero. 2  Natural reversal, also known as recanalization. 3  Surgical error.
The good news is that most men have two testicles, and therefore two separate procedures during a vasectomy reversal, and two chances for success. Overall, depending on the length of time since vasectomy, rates of sperm recovery after vasovasostomy is 71-97%, with a 30-76% pregnancy rate.
