The ______ is a male contraceptive technique that involves a minimally invasive procedure to block the vas deferens.

Correct option is D

Sol. Vasectomy is a male sterilization procedure in which the vas deferens (sperm-carrying tubes) are cut, sealed, or blocked to prevent sperm from mixing with semen. It is a minimally invasive and permanent form of contraception for men. The procedure does not affect testosterone levels, libido, or overall sexual function.
Explanation of each option:
· (a) Intrauterine device (IUD) – Incorrect. IUDs are female contraceptive devices placed inside the uterus to prevent pregnancy, not a male contraceptive technique.
· (b) Spermicide – Incorrect. Spermicides are chemical substances that kill or disable sperm and are used as a temporary contraceptive method, not a surgical procedure.
· (c) Condom – Incorrect. Condoms are barrier contraceptive methods that prevent sperm from entering the female reproductive tract but do not involve blocking the vas deferens.
· (d) Vasectomy – Correct answer. Vasectomy is a permanent and effective male contraceptive method that prevents sperm from being released during ejaculation.
