Vasectomy Reversal

In the absence of spermatozoa in the semen, associated with obstruction of the seminiferous tubules (obstructive azoospermia), it is possible to restore their patency microsurgery.
The term reverse vasectomy comes from the United States, where surgical sterilization of men (vasectomy) was the most popular method to avoid unwanted pregnancy in a partner. But in 20% of cases, situations demanded to restore the fertility of a man through a reverse vasectomy.
Reverse vasectomy is a complex reconstructive surgery performed on the seminal ducts, which is carried out exclusively using microsurgical methods.
There are two types of reverse vasectomy: vasovasostomy, which connects the passable parts of the vas deferens, and vasoepididymostomy, in which a tubule of the epididymis and the vas deferens are sutured.
Complexity of these microsurgical methods of reverse vasectomy lies in the fact that tubules less than 1 mm in diameter have to be sutured.
Among urologists trained in male reproductive microsurgery, the success rate of reverse vasectomy is over 90%. Thus, most of the men who undergo this operation are able to conceive naturally.
