Levonorgestrel is a synthetic progestin widely used for hormonal contraception and emergency contraceptive therapy. It acts by preventing ovulation, thickening cervical mucus, and altering the endometrial lining, thereby reducing the likelihood of fertilization and implantation. It is orally active, highly potent at low doses, and forms the active component of many contraceptive pills, intrauterine systems, and emergency contraceptive products.
Levonorgestrel works by suppressing ovulation through inhibition of the luteinizing hormone (LH) surge. It also increases cervical mucus viscosity, which prevents sperm from reaching the egg, and alters endometrial receptivity, reducing the likelihood of implantation. Additionally, it exhibits high receptor selectivity, minimizing androgenic and estrogenic side effects while effectively providing contraceptive action.
