  1. A
    Intra uterine devices: Increase phagocytosis of sperms, suppress sperm motility and fertilizing capacity of sperms
  2. B
    Hormonal contraceptives: Prevent/retard entry of sperms, prevent ovulation and fertilization
  3. C
    Vasectomy: Prevents spermatogenesis
  4. D
    Barrier methods: Prevent fertilization

Solution & Step-by-step Explanation

Vasectomy is a surgical method (sterilization) where a small part of the vas deferens is removed or tied up. It prevents the transport of sperm into the urethra, thereby preventing conception, but it does not stop the process of spermatogenesis (sperm production) in the testes.
