Correct answer: C — Use alternative contraception until post-vasectomy semen analysis confirms clearance

Vasectomy is not immediately effective; alternative contraception is required until post-vasectomy semen analysis confirms clearance according to the service protocol. Stopping immediately or after one ejaculation risks pregnancy. EC is not a planned substitute for contraception, and lifelong annual semen analysis is not routine. The pearl is that vasectomy counselling must include delayed effectiveness.
