Contraception refers to methods or devices used to prevent pregnancy during sexual intercourse. It allows individuals and couples to plan if and when they want to have children. Common forms of contraception include birth control pills, condoms, and intrauterine devices (IUDs). Each method works differently, providing various options based on personal preferences and health needs. Using contraception can also have health benefits, such as regulating menstrual cycles and reducing the risk of certain diseases. It's important for people to understand their options and consult with healthcare providers to choose the best method for their lifestyle and circumstances.
