A vasectomy is considered a permanent method of birth control. Vasectomy reversal (for example, vasovasostomy) reconnects the tubes (vas deferens) that were cut during a vasectomy. Success of a vasectomy reversal depends on a number of factors including, how much time has passed since the original vasectomy, the skill of the surgeon performing the vasectomy reversal and the condition of the tissues at the time of reversal.
Men who have had a vasectomy for less than 3 years can expect a better vasectomy reverse success rate (90-97%) compared to those with a greater than 10 year time lapse (79-88%). Overall pregnancy rates range from 35 to perhaps 70%.
The procedure to reverse the vasectomy is technically more complicated, takes longer and usually is performed with the use of a special operating microscope.
Over time, additional blockages can form, and some men develop antibodies to their own sperm. Sometimes the vas deferens is reconnected to the epididymis (vasoepididymostomy) because of a secondary obstruction in the epididymis.
