What does it involve?
The tubes that carry sperm are interrupted. The technique, anesthesia, recovery and possible risks are explained during consultation.
It is not effective immediately
Another contraceptive method must be used until your doctor confirms the semen test result and tells you it can be stopped.
What to consider
It should be considered permanent: reversal does not guarantee restored fertility. It does not protect against sexually transmitted infections. A prior assessment helps decide whether it is right for you.
