Norgestrel is a synthetic progestin hormone used in birth control pills and other hormonal medications. It is a progestin, a synthetic progesterone hormone similar to the natural progesterone hormone produced in the body. It works by preventing ovulation and thickening the cervical mucus, making it difficult for sperm to reach the uterus. It may also change the lining of the uterus, making it difficult for a fertilized egg to implant. Norgestrel may be used alone or in combination with other hormones.
D-norgestrel, also known as levonorgestrel (LNG), is a synthetic progestin used in various forms of hormonal contraception and some hormone therapy applications. Here's a breakdown of its key aspects:
Purpose:
- Primarily used for:
- Preventing pregnancy: Available in various forms like birth control pills, implants, and intrauterine devices (IUDs) to prevent ovulation and thicken cervical mucus, making it difficult for sperm to reach the egg.
- Emergency contraception: Often referred to as the "morning-after pill," it can be used within 72 hours of unprotected sex to prevent pregnancy.
- Hormone therapy: In some cases, it may be used to treat menstrual irregularities, endometriosis, or certain hormonal imbalances.
Mechanism of action:
- Mimics the effects of the natural hormone progesterone in the body.
- Primarily works by:
- Suppressing ovulation (egg release)
- Thickening cervical mucus to hinder sperm movement
Important information:
- Prescription or over-the-counter (OTC): Depending on the form and dosage, d-norgestrel may be available by prescription or over-the-counter.
