Hormonal IUDs

Hormonal IUDs[edit | edit source]

Hormonal IUDs are a type of intrauterine device that release a progestin hormone called Levonorgestrel. They are used for contraception, to treat heavy periods, and to prevent endometrial hyperplasia and endometrial cancer.

Etymology[edit | edit source]

The term "intrauterine" comes from Latin intra, meaning "within", and uterus, meaning "womb". The term "device" is derived from the Old French devis, meaning "division, separation, disposition, regulation, order; wish, desire; contrivance, plan, scheme". The term "hormonal" is derived from the Greek hormon, meaning "that which sets in motion".

Mechanism of action[edit | edit source]

Hormonal IUDs release levonorgestrel into the uterus. Levonorgestrel is a type of progestin, which is a synthetic form of the hormone Progesterone. This hormone thickens the mucus in the cervix, which makes it difficult for sperm to reach and fertilize an egg. It also thins the lining of the uterus, which makes it less likely that a fertilized egg will attach and grow.

Types of Hormonal IUDs[edit | edit source]

There are several types of hormonal IUDs available, including Mirena, Kyleena, Liletta, and Skyla. These IUDs vary in the amount of levonorgestrel they release and their approved duration of use.

Side effects[edit | edit source]

Common side effects of hormonal IUDs include irregular bleeding, amenorrhea, ovarian cysts, and hormonal side effects such as acne, headaches, and breast tenderness. Serious side effects are rare but can include uterine perforation and infection.
