Unlike most other issues related to vasectomy, this question has a very simple answer:
You can have sex as often as you like before a vasectomy, and at any time up until the operation.
Most men know they can’t have sex or masturbate for a certain period of time after their vasectomy, so they may be tempted to squeeze in a few last minute lovemaking sessions with their partner before the operation. Thankfully, this is completely fine and will not cause any problems with your procedure. There is no medical reason not to have sex before a vasectomy.
It’s important to remember that having sex after a vasectomy is a completely different subject, so we recommend reading our article on how long you need to wait after a vasectomy to have sex if you want to learn more.
