How will I know my vasectomy has worked?

If you have a vasectomy at Marie Stopes UK, we will carry out a semen test after your procedure to ensure that the vasectomy has been successful.

Semen testing after 16 weeks

You will be given two sample kits on the day of your treatment to take home as well as exact dates to take and send in the samples. We will test the ejaculate 16 weeks after the procedure to ensure there's no longer sperm in it. 

Read our advice on how to use your vasectomy testing kit.

Contraception needed untill you get the 'all clear' 

You will need to use other contraceptive methods until you have received the all-clear from Marie Stopes UK, otherwise your partner may become pregnant.
