A contraceptive pill prevents ovulation by
- blocking Fallopian tube ,
- inhibiting release of FSH and LH
- stimulating release of FSH and LH
- causing immediate degeneration of released ovum.
The Correct Option is B
Solution and Explanation
Birth control pills, also known as contraceptive pills, are a widely used form of contraception aimed at preventing pregnancy. These pills consist of synthetic steroid hormones, which can either contain progestin alone or a combination of progestin and estrogen.
The primary mechanism of action of contraceptive pills involves the suppression of hormones released by the pituitary gland, namely luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones are crucial for the normal functioning of the ovaries. When FSH and LH levels are suppressed, ovulation—the release of a mature egg from the ovary—is inhibited. This, in turn, significantly reduces the likelihood of fertilization by a male sperm cell.
Contraceptive pills containing only progestin have an additional mechanism of action. They work by thickening the mucus in the cervix, making it more difficult for sperm to penetrate and reach the egg, even if ovulation were to occur.
Overall, contraceptive pills offer an effective means of birth control by altering hormonal levels and inhibiting ovulation, thereby preventing pregnancy.

Concepts Used:
Reproductive Health
- The biological process by which a new individual or an offspring is produced from a parent or parents that are biologically similar or identical is known as reproduction. It is the elemental trait of all known forms of life. In fact, each and every individual have life because of reproduction.
- The state or position of male and female reproductive systems during their lifetime refers to their reproductive health. The system comprises organs and glands, including the pituitary gland in our brain, which are responsible for the production and release of hormones.
- In other words, reproductive health can be described as a state of physical, mental, and social well-being in all aspects relating to the reproductive system. It includes the liberation and appropriate capacity to reproduce as and when one decides to do so, apart from having a safe and satisfying sex life.
