Hormonal methods refer to the use of synthetic hormones to prevent pregnancy. These methods work primarily by preventing ovulation, thickening cervical mucus to block sperm, and thinning the lining of the uterus to prevent implantation. In the context of Pediatrics, hormonal methods are often considered for adolescents for various reasons, including contraception, menstrual regulation, and treatment of medical conditions like acne and polycystic ovary syndrome (PCOS).
