The birth control pill works by stopping sperm from joining with an egg (which is called fertilization). The hormones in the pill stop ovulation. No ovulation means there's no egg hanging around for sperm to fertilize, so pregnancy can't happen. The pill's hormones also thicken the mucus on the cervix.

Oral contraceptive pills contain estrogen and progesterone, that preve...
Explanation:
Oral contraceptive pills are a popular form of birth control that contain synthetic versions of the hormones estrogen and progesterone. These hormones work together to prevent pregnancy by inhibiting the release of the secondary oocyte from the ovary.
Prevention of Formation of New Ovarian Follicles:
- Estrogen and progesterone in oral contraceptive pills suppress the production of the follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the pituitary gland.
- FSH and LH are responsible for the formation and development of ovarian follicles, which contain the eggs.
- Therefore, the use of oral contraceptive pills prevents the formation of new ovarian follicles, reducing the number of available eggs for fertilization.
Prevention of Release of Secondary Oocyte from Ovary:
- Estrogen and progesterone in oral contraceptive pills also inhibit the surge of LH hormone that triggers ovulation.
- This prevents the release of the secondary oocyte from the ovary, which is necessary for fertilization to occur.
- Without the release of the secondary oocyte, there is no egg available for fertilization by sperm, thereby preventing pregnancy.
Prevention of Implantation of Fertilized Egg in the Uterus:
- Oral contraceptive pills primarily work by preventing ovulation, which is the release of a mature egg from the ovary.
- If ovulation does not occur, there is no egg available for fertilization.
- Therefore, the prevention of implantation of a fertilized egg in the uterus is not a direct mechanism of action of oral contraceptive pills.
Correct Answer:
The correct answer is option 'B' - release of secondary oocyte from the ovary. Oral contraceptive pills mainly work by inhibiting ovulation, preventing the release of the secondary oocyte from the ovary.
