  • Retired account

    Generally speaking, after a vasectomy how many ejaculations does it take to expend all the viable sperm?

    Dr. Edward Karpman

    The maximum number of ejaculates necessary to clear all sperm downstream from the vasectomy site can be as high as 24. This number is highly variable and most men will become azoospermic after fewer than 24 ejaculates. It is important that every man confirm the absence of sperm prior to having unprotected intercourse.
