Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Semen analysis shows azoospermia, usually after about 3 months or 20 ejaculations

Sperm remain in the vas distal to the occlusion for some time, so alternative contraception is used for about 3 months (20 ejaculations) until a semen analysis shows azoospermia. Non-scalpel vasectomy is a safe day-care procedure.

Option by option

  • A. The next day

    Residual sperm persist beyond the first day.

  • B. One week

    One week is too short.

  • C. Semen analysis shows azoospermia, usually after about 3 months or 20 ejaculations (correct)

    Correct. Azoospermia must be documented.

  • D. One year

    One year is unnecessarily long.
