Explanation
Birth control pills, also known as oral contraceptives, are a popular method for preventing pregnancy. They work by stopping the release of eggs from the ovaries and making other changes in the body that help prevent pregnancy.
Effectiveness:
- When taken correctly, birth control pills are more than 90% effective. This means that fewer than 1 in 10 people using them will get pregnant in a year.
How They Work:
- The pills contain hormones that stop the ovaries from releasing eggs.
- They also thicken the mucus in the cervix, making it harder for sperm to enter the uterus.
Considerations:
- It's important to take the pill at the same time every day for the best protection.
- Missing doses can lower effectiveness.
Overall, birth control pills are a reliable choice for many people looking to prevent pregnancy, but they need to be used as directed to work best.
