In most cases the vas deferens can be reattached but, in many cases, fertility is not achieved. There are several reasons for this, including blockages in the vas deferens, and the presence of autoantibodies which disrupt normal sperm activity. If blockage at the level of the epididymis is suspected, a vasoepididymostomy can be performed. Return of sperm to the ejaculate depends greatly on the length of time from the vasectomy and the skill of the surgeon. Generally, the shorter the interval, the higher the chance of success. The likelihood of pregnancy can depend on female partner factors. Over half of men who have undergone a vasectomy develop anti-sperm antibodies. The effects of anti-sperm antibodies continue to be debated in the medical literature, but there is agreement that antibodies may reduce sperm motility.
