Progestin is a synthetic form of the hormone progesterone, which is naturally produced in the body. It plays a crucial role in regulating the menstrual cycle and maintaining pregnancy. Progestin is commonly used in various forms of hormonal contraceptives, such as birth control pills, implants, and injections, to prevent ovulation and manage menstrual disorders. In addition to contraception, progestin is also used in hormone replacement therapy for women experiencing menopause symptoms. It helps balance hormone levels and can reduce the risk of endometrial cancer when used alongside estrogen. Progestin is an important tool in reproductive health and family planning.
