उत्तर
Synthetic hormones that control the menstrual cycle are commonly used in oral contraceptive pills. These hormones can:
- Prevent ovulation: The hormones can stop the release of an egg from the ovaries.
- Thin the uterine lining: This makes it less likely for a fertilised egg to implant.
- Thicken cervical mucus: This makes it difficult for sperm to reach the egg.
