Progestogens

Progestogens are a type of steroid hormone that bind to and activate the progesterone receptor. They are essential for the regulation of reproduction and the menstrual cycle. Progestogens include endogenous progestogens like progesterone and synthetic progestogens known as progestins.

Function

Progestogens play a crucial role in the menstrual cycle and pregnancy. They prepare the endometrium for implantation of an embryo, and in pregnancy, they prevent further ovulation and maintain the function of the placenta. They also have important effects on the mammary glands and nervous system.

Types

There are two main types of progestogens: endogenous and synthetic. Endogenous progestogens, such as progesterone, are produced naturally in the body. Synthetic progestogens, also known as progestins, are man-made and are used in contraceptive methods and hormone therapy.

Medical uses

Progestogens are used in a variety of medical applications. They are used in contraceptive methods, such as birth control pills, intrauterine devices, and emergency contraception. They are also used in hormone therapy for menopausal symptoms, infertility, and certain types of cancer.

Side effects

Like all medications, progestogens can have side effects. These can include mood changes, weight gain, breast tenderness, and headaches. In rare cases, they can cause more serious side effects like blood clots and stroke.
