Introduction: Birth control pills are a popular and effective method of contraception used by millions of individuals worldwide. This article provides an overview of birth control pills, their types, how they work, and the advantages and disadvantages associated with their use.
- Types of Birth Control Pills: There are two primary categories of birth control pills: combination pills and progestin-only pills. Combination pills contain both 避孕 estrogen and progestin hormones, while progestin-only pills contain only a progestin hormone. The choice between the two depends on an individual’s specific needs and health considerations.
- How Do Birth Control Pills Work? Birth control pills primarily prevent pregnancy by suppressing ovulation. They inhibit the release of an egg from the ovaries, making it less likely for sperm to fertilize an egg. Additionally, they thicken cervical mucus, making it more challenging for sperm to reach an egg.
