Question

Quizplus · Accepted Answer

The most widely used and most effective birth control pill contains both estrogen and progesterone. These hormones work together to prevent ovulation, thicken cervical mucus to prevent sperm from reaching the egg, and thin the lining of the uterus to make it less receptive to a fertilized egg. Luteinizing hormone is not used in birth control pills, and while androgen hormones may be used in some pills, they are not as effective as those containing estrogen and progesterone.
