Answer: 4. Vasectomy - prevents spermatogenesis

Key idea: Vasectomy blocks the transport of sperms; it does not stop spermatogenesis.

In vasectomy the vas deferens is cut and tied, so sperms cannot reach the semen, but the testes continue to make sperms. The other rows are correct: barriers prevent fertilization, IUDs increase phagocytosis and suppress sperm motility, and hormonal pills stop ovulation and alter the cervical mucus.
