How long do I have to wait to have sex after a vasectomy?

After the vasectomy procedure, am I infertile right away? Or do I need to wait for a certain amount of time to pass after the procedure?

No!!! Usually your doctor will have you wait 3 months and ejaculate at least 25 times before you check. Even then about 15% of patients still have a few sperm left.

There is certainly sperm above the area where the vas takes place and you could easily achieve a pregnancy after the vasectomy. I recommend 15 ejaculations with protection\contraception followed by a microscopic examination of the 16 and 17 ejaculates. If no sperm is seen, then I consider the man to be sterile and no further semen examinations are necessary.

No you are not infertile right away . It takes approximately 16 ejaculations and a semen analysis to show no sperms before you are declared infertile

Safe rule is to wait one week after vasectomy to have sex and use birth control for 3 months.
