Vasectomy Reversal
A vasectomy reversal reconnects the tubes that carry sperm, aiming to restore fertility after a vasectomy.
Quick answer
Vasectomy Reversal: what it is, why it's done and what happens
A vasectomy reversal rejoins the vas deferens tubes that were cut or sealed during a vasectomy, so that sperm can once again reach the semen. It is delicate microsurgery.
- Why it is done: It is chosen by men who have had a vasectomy but now wish to father children, for example after a change in circumstances.
- What happens: Under general or local anaesthetic, the surgeon uses a microscope to reconnect the tiny tubes through small cuts in the scrotum.
What it is
A vasectomy reversal rejoins the vas deferens tubes that were cut or sealed during a vasectomy, so that sperm can once again reach the semen. It is delicate microsurgery.
Why it is done
It is chosen by men who have had a vasectomy but now wish to father children, for example after a change in circumstances. It is usually done privately rather than on the NHS.
What happens
Under general or local anaesthetic, the surgeon uses a microscope to reconnect the tiny tubes through small cuts in the scrotum. The operation is precise and can take 2–4 hours.
Recovery
Soreness and swelling settle over one to two weeks with supportive underwear and rest. Sperm may take several months to reappear in the semen, and semen tests check whether the reversal has worked.
Good to know
Risks and things to consider
Success is not guaranteed and falls the longer it has been since the vasectomy. Even when tubes reconnect, pregnancy may not follow. Risks include bleeding, infection and ongoing discomfort.

Answers
Vasectomy Reversal: frequently asked questions
How successful is a vasectomy reversal?
Success depends largely on how long ago the vasectomy was done — chances are higher when reversed sooner. Sperm returning to the semen does not always lead to pregnancy, so results vary.
How long until I know if it worked?
Sperm can take several months to reappear after reconnection, so semen tests are done over the following months to check whether the reversal has been successful.
