Norgestrel

Introduction

Norgestrel is a synthetic progestin used primarily in hormonal contraceptives. It is commonly found in birth control pills and emergency contraceptive formulations. Norgestrel mimics the natural hormone progesterone, which plays a key role in the female reproductive cycle. By altering hormone levels, Norgestrel helps prevent ovulation, thicken cervical mucus, and modify the uterine lining, making it less suitable for implantation. It is often combined with estrogen in oral contraceptives or used alone in progestin-only pills (POPs). Norgestrel is effective, convenient, and widely prescribed for managing fertility and menstrual health.

Uses of Norgestrel

• Contraception (birth control)
• Emergency contraception (morning-after pill)
• Regulation of menstrual cycles
• Treatment of endometriosis and menstrual disorders
• Hormonal therapy in menopausal women (as part of combined HRT)

How Norgestrel Works

Norgestrel prevents pregnancy mainly by inhibiting ovulation (release of an egg from the ovary). It also thickens cervical mucus, which blocks sperm movement, and alters the endometrial lining, reducing the chances of implantation. These combined actions help prevent fertilization and conception.

Benefits of Norgestrel

• Helps in regulating irregular menstrual cycles
