Hormonal birth control refers to methods of preventing pregnancy that use hormones to regulate a woman's reproductive system. These methods include birth control pills, patches, injections, and implants. They work primarily by preventing ovulation, which means that no egg is released for fertilization. In addition to preventing pregnancy, hormonal birth control can also help manage menstrual cycles and reduce symptoms of conditions like polycystic ovary syndrome (PCOS) and endometriosis. It is important for individuals to consult with a healthcare provider to determine the most suitable option based on their health needs and lifestyle.
