Levonorgestrel is a versatile progestogen hormone used extensively in reproductive health for both long-term contraception and emergency pregnancy prevention. It works by preventing ovulation or altering the uterine lining to prevent fertilisation. It is a key component in many cost-effective generic contraceptive pills and emergency treatments.
