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 success of vasectomy is not 100 percent. Approximately 1 in 200-400 patients who undergo vasectomy will not have sperm permanently removed from their ejaculate. To put this in to perspective, the failure rate of preventing pregnancy with condoms is approximately 30 percent.
