What is the primary use of contraception medications?

The primary use of contraception medications is to intentionally prevent pregnancy. These medications work by regulating hormones and altering the menstrual cycle to prevent ovulation, inhibit fertilization, or prevent implantation of a fertilized egg. Contraceptives can come in various forms, including pills, patches, injections, and intrauterine devices, all designed specifically for the purpose of birth control. While some hormonal contraceptives may have secondary benefits, such as regulating menstrual cycles or treating certain hormonal conditions, their main function is to serve as a reliable method of preventing unintended pregnancy.
