Vasoepididymostomy is microsurgery that connects the vas deferens directly to the epididymis. The connection bypasses a blockage that prevents sperm from entering the vas deferens. It may be performed during a vasectomy reversal when reconnecting the vas deferens alone is unlikely to work. Restoring a passage for sperm does not guarantee pregnancy.
read more about vasoepididymostomy ...The procedure may be needed when there is a blockage within the epididymis. During vasectomy reversal, the surgeon examines fluid from the vas deferens to help choose the operation. The decision may not be clear until surgery is underway. A vasoepididymostomy can be performed on one side and a different reversal procedure on the other.
The surgeon makes a scrotal incision and identifies the vas deferens and epididymis. Under magnification, a suitable epididymal tubule is opened. Fine stitches join that tubule to the vas deferens. The new connection gives sperm a route around the blockage.
Scrotal swelling and soreness can occur after surgery. The surgeon provides instructions for wound care, support, and activity restrictions. Follow-up semen analyses check whether sperm appear in the semen. It may take months for results to become clear.
Risks include bleeding, infection, and the new connection becoming blocked. Sperm may not return even when the surgery is completed. Pregnancy also depends on other fertility factors. A microsurgeon can discuss the expected outcome based on the operative findings.
Vasovasostomy reconnects the two cut ends of the vas deferens. Vasoepididymostomy connects the vas deferens directly to the epididymis to bypass a blockage.
No. The surgeon may decide during the operation after examining fluid from the vas deferens.
Follow-up semen analyses show whether sperm have entered the semen. Pregnancy is a separate outcome and is not assured by sperm return.
Yes. A surgeon may perform vasoepididymostomy on one side and vasovasostomy on the other if the findings differ.
