• B. Blocking the transport of gametes
• C. Blocking the entry of sperms through cervix
• D. Blocking action of endogenous progesterone

Answer 1

The correct option is B Blocking the transport of gametes

Terminal method of contraception or sterilisation procedure in the male is called ‘vasectomy’ and in the female is called ‘tubectomy’. In vasectomy, a small part of the vas deferens is removed or tied. In tubectomy, a small part of the fallopian tube is removed or tied up. These techniques provide contraception by blocking the transport of gametes. They do not prevent formation of gametes.
