There are two methods of vasectomy reversal - vasovasostomy and vasoepididymostomy. It is not possible to determine before hand which of these two microsurgical vasectomy reversal procedures a man might require. This decision is made by the operating urologist during the vasectomy reversal surgery.
Both methods of vasectomy reversal - vasovasostomy and vasoepididymostomy are performed using an operating microscope and miniature instruments.
During the vasectomy reversal surgery, fluid from the cut end of the vas deferens is examined under the microscope for the presence of sperms. If sperms are present, then usually a vasovasostomy is performed. If no sperms are detected, then generally a vasoepididymostomy is performed. Several other factors such as examination of the epididymis by the urologist for the presence of blockage, the length of the testicular end of the vas deferens and the appearance and consistency of the fluid obtained from the cut end of the vas deferens are taken into consideration before deciding on the method of vasectomy reversal.
Vasovasostomy is the most common type of vasectomy reversal surgery. This procedure is performed if the microscopic examination of the fluid extracted from the vas deferens show the presence of sperms. The two cut and blocked ends of the vas deferens are reconnected to establish sperm flow.
Vasovasostomy is simpler than vasoepididymostomy and the costs of the surgery are less. This method of vasectomy reversal surgery takes less time and recovery is faster. The success rate of sperms returning to the semen, and the pregnancy rate after vasectomy reversal are higher with this type of surgery.
Vasoepididymostomy is a more complex procedure of vasectomy reversal. It is generally done if a microscopic examination of the fluid obtained from the vas deferens does not show any sperms. Epididymis is a tube like structure where the sperms are stored and matured. During vasoepididymostomy the cut end of the vas deferens is connected directly to the epididymis.
The procedure of vasoepididymostomy generally takes about 3 hours to perform. The costs of this surgery are more than the costs of vasovasostomy. The chances of pregnancy after vasoepididymostomy are much lesser than after vasovasostomy.
Some patients may require a vasovasostomy on one side and a vasoepididymostomy on the other.
Epididymis: Epididymis is a tube-like structure which connects the testis and the vas deferens. The sperms are stored and matured in the epididymis.
Sperms: Sperms are male reproductive cells. They are produced in the testes. They are carried in fluid called semen. Sperms are capable of fertilising an egg cell to form a zygote.
Vas deferens: Vasa deferentia are thin tubes which carry sperms from the testes to the urethra. Vas deferens is also known as sperm duct. Each vas deferens is about 45 cms long.
Vasovasostomy: Vasovasostomy is a method of vasectomy reversal surgery where the two cut ends of the vas deferens are reconnected.
Vasoepididymostomy: Vasoepididymostomy is a method of vasectomy reversal surgery where the vas deferens is connected to the epididymis.
Testes: Testes (singular=testis) are the male gonads. They are situated in the scrotum. They produce sperms and the male hormone, testosterone.
