Final answer:
Hormonal birth control prevents pregnancy by blocking ovulation, thickening cervical mucus, and altering the uterine lining.

Hormonal birth control methods prevent pregnancy primarily by preventing ovulation. These methods involve the administration of hormones that inhibit ovulation, thickening of cervical mucus, and changes in the uterine lining, making it less hospitable for implantation. By interfering with these processes, hormonal birth control effectively reduces the chances of pregnancy.
