Solution

The correct option is D Gametogenesis initiation

Gametogenesis refers to the process that leads to formation of sex cells in both males and females. In females, the multiplication phase of gametogenesis starts before birth while in males, it occurs after attaining sexual maturity. Hence it cannot be used as a target for birth control.

Ovulation (formation of egg) is inhibited by the pills containing progesterone-estrogen hormone combinations.

Implantation is the process of attachment of the blastocyst on the wall of the uterus after fertilisation. Oral contraceptive pills mostly inhibit ovulation and implantation

Fertilisation is the process of fusion of sperm and egg cells inside the female body. Surgical birth control methods and some Intra Uterine devices restrict the movement of sperm to the site of fertilisation.

Ovulation (formation of egg) is inhibited by the pills containing progesterone-estrogen hormone combinations.
