Question: How do oral contraceptives specifically birth control pills prevent pregnancy?
Oral contraceptives, also known as birth control pills, work by using synthetic hormones to prevent ovulation, which is the release of an egg from the ovary. When taken correctly, these pills inhibit the natural hormones that stimulate the ovaries to produce and release eggs, preventing ovulation. Without ovulation, there is no egg available to be fertilized by sperm, which in turn prevents pregnancy. Additionally, birth control pills cause the cervical mucus to thicken, making it difficult for sperm to penetrate and reach the egg, and also alter the lining of the uterus, making it less receptive to implantation of a fertilized egg. As a result, birth control pills are highly effective in preventing pregnancy when taken consistently and correctly.
