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.
When men undergo a vasectomy, their sperm can no longer reach the semen; as a result, any semen that is ejaculated during sex does not contain sperm, which is needed to fertilize a woman's egg. A vasectomy is a very effective and permanent means of preventing pregnancy.
