What does it do?

Levonorgestrel is a synthetic progestin analog of female hormones. It is primarily used for contraceptive purposes and regulates female reproductive functions to prevent pregnancy. It is included in various oral contraceptives.

Levonorgestrel acts on the female reproductive system to suppress ovulation. It also alters the endometrium, making it difficult for a fertilized egg to implant. This effectively prevents pregnancy.
