How soon after a vasectomy can I have sex?

You can have sex again as soon as it is comfortable to do so, although it is best to wait for a couple of days. However, you will still have sperm in your semen immediately after the operation, as it takes time to clear the remaining sperm in your tubes. It takes an average of 20-30 ejaculations to clear the tubes of sperm completely. You will need to use another method of contraception until you have had two clear semen tests.

Once the operation has been carried out successfully and semen tests have shown that there is no sperm present, long-term partners may not need to use other forms of contraception.

However, a vasectomy does not protect against HIV infection or any other STI's, so you should still use condoms with any new partner.
