Female contraceptives are methods used to prevent pregnancy. They work by inhibiting ovulation, blocking sperm from reaching an egg, or altering the uterine lining to prevent implantation. Common types include birth control pills, condoms, IUDs, and implants. Each method has different effectiveness rates and side effects. Many female contraceptives are available by prescription, while others, like condoms, can be purchased over-the-counter. It's important for individuals to consult with a healthcare provider to choose the most suitable option based on their health, lifestyle, and family planning goals.
