Contraceptive methods are techniques used to prevent pregnancy during sexual intercourse. They can be categorized into several types, including barrier methods like condoms, hormonal methods such as birth control pills, and intrauterine devices (IUDs). Each method works differently; for example, barrier methods physically block sperm from reaching the egg, while hormonal methods regulate a woman's hormones to prevent ovulation. In addition to these, there are also natural methods, like fertility awareness, and permanent options, such as sterilization. Choosing the right contraceptive method depends on individual health, lifestyle, and family planning goals. Consulting a healthcare provider can help individuals make informed decisions.
