Hormonal IUD

Hormonal IUD‏‎

The Hormonal Intrauterine Device (IUD) is a type of long-acting reversible contraception (LARC) that is placed inside the uterus for the purpose of preventing pregnancy. It is a small, T-shaped device that releases a progestin hormone called levonorgestrel, which is similar to the hormone progesterone that is naturally produced by a woman's body.

Mechanism of Action

The Hormonal IUD works by releasing levonorgestrel into the uterus, which thickens the mucus in the cervix to prevent sperm from reaching or fertilizing an egg. It also thins the lining of the uterus, which makes it less likely for a fertilized egg to attach to it.

Types of Hormonal IUDs

There are several types of Hormonal IUDs available, including Mirena, Kyleena, Liletta, and Skyla. These IUDs vary in size, amount of hormones released, and duration of effectiveness.

Effectiveness

Hormonal IUDs are one of the most effective forms of birth control available. They have a failure rate of less than 1%, meaning that less than 1 out of 100 women will get pregnant each year if they use a Hormonal IUD.

Side Effects and Risks

While Hormonal IUDs are generally safe, they do carry some risks and potential side effects. These can include irregular bleeding, ovarian cysts, and in rare cases, perforation of the uterus or infection.

Removal

A Hormonal IUD can be removed at any time by a healthcare provider. After removal, fertility usually returns quickly.
