Contraceptives are a wide range of methods and devices used to prevent unwanted pregnancies. These can include hormonal methods such as birth control pills, patches, and injections, as well as barrier methods like condoms, diaphragms, and cervical caps. Some contraceptives, like intrauterine devices (IUDs) and sterilization surgeries, provide longer-term protection. Additionally, natural family planning methods, such as tracking ovulation and abstaining from sex during fertile times, can also be used to prevent pregnancy. The choice of contraceptive method depends on individual preferences, health considerations, and lifestyle factors.
