How to prepare yourself for the vasectomy
It is important to prepare yourself to contribute to a successful vasectomy. Please read carefully what you need to do yourself.
Informed Consent
Before the sterilization procedure can take place, it is important that you carefully review the informed consent form and provide your consent for the procedure.
The informed consent form must be fully completed before the procedure can be carried out. You can find the form in your personal portal.
Three days before the vasectomy
- Three days before the procedure you are requested to shave your pubic hair, especially your scrotum (ball sack) with a razor or an electric shaver.
Day of the vasectomy
- To prevent infection, please wash yourself thoroughly with water and soap on the day of the procedure.
- You are allowed to eat normally on the day of the procedure.
- After the procedure, you are not allowed to drive a car or ride a bike. We advise you to ask someone to accompany you to the appointment.
- Make sure to wear tight-fitting and comfortable underwear or swim shorts on the day of the procedure.
- We advise you to take two 500mg paracetamol (acetaminophen) tablets just before you leave your house.

Do you use blood-thinning medications?
If you use blood thinners, there may be an increased risk of bleeding. Therefore, it is necessary that you stop taking these medications a few days prior to the procedure.
Do you have questions about using blood thinners or about when you should stop? Please contact one of our nurses at: pos-comp@mannenkliniek.nl.
