Explanation of Solution

The ovulation is the process during which a mature egg is released from an ovary. The increased levels of estrogen signal the pituitary gland to release LH hormone, which stimulates the process of release of a mature egg. Birth pills or oral contraceptives are consumed to prevent pregnancy.

The pill contains a mixture of estrogen and progastrin, which prevent the release of LH hormone and FSH hormone from the pituitary gland. The progestin inhibits the ovulation.
