After a vasectomy, it is generally recommended to wait at least 2 to 7 days before ejaculating or having sex. Some sources specifically advise waiting about 48 hours if there is no pain, while others recommend waiting up to a week to allow the surgical site to heal and minimize risks such as infection or pain. Early ejaculation can be uncomfortable and may increase complications like swelling or sperm granuloma. However, once the initial healing period is over and any pain or swelling subsides, ejaculation can typically resume without significant issues. It is important to note that even after resuming ejaculation, the vasectomy is not immediately effective for contraception. It usually takes about 12 weeks and around 15 to 20 ejaculations to clear sperm completely from the semen. Therefore, other birth control methods should be used during this time until confirmed sperm-free by semen analysis. In summary:
- Wait about 2 to 7 days before ejaculating to allow healing.
- Start ejaculating again only when comfortable and pain-free.
- Continue using contraception for about 12 weeks or until clearance.
- Ejaculation after this period is normal and the procedure does not affect libido or sexual function.
This guidance is consistent across multiple medical sources and urology centers.
