Question

Quizplus · Accepted Answer

Combination birth control pills contain synthetic versions of both estrogen and progesterone, which work together to suppress the release of luteinizing hormone (LH), follicle-stimulating hormone (FSH), and gonadotropin-releasing hormone (GnRH). This prevents ovulation from occurring and therefore prevents pregnancy.
