It can take several months for sperm to re-appear in your semen, particularly if you’ve had a vasoepididymostomy. Your surgeon may need to keep retesting your semen every few months. If you don’t have semen in your sperm after a year and a half, they may discuss alternative fertility treatments with you. To find out more, see our Recovery section.
This depends on how long it’s been since you had a vasectomy. If it’s within 3 years, the success rate is much higher: around 75 in 100 people go on to have a pregnancy with their partner. This drops to 55 in 100 people if it’s been between 3 and 8 years. However, starting a pregnancy depends on a number of other factors as well as the success of a vasectomy reversal. To find out more, see our About section.
A vasectomy reversal is usually done under general anaesthesia, so you’ll be asleep and won’t feel anything. But you may have some pain once the anaesthetic wears off. Your doctor may give you a nerve block (injection) to help with this. You can also take over-the-counter painkillers and use ice packs as necessary. To find out more, read our Recovery section.
