Hormonspiralen

Hormonspiralen, also known as a hormonal intrauterine device (IUD), is a small, T-shaped piece of plastic inserted into the uterus. It is a highly effective method of reversible contraception. The primary mechanism of action is the slow release of a progestin hormone, levonorgestrel, directly into the uterus. This hormone thickens cervical mucus, making it difficult for sperm to reach the egg, and also thins the uterine lining, preventing implantation if fertilization does occur. In some cases, it can also inhibit ovulation.

Hormonspiralen is inserted by a healthcare professional and can remain in place for three to eight years, depending on the specific type. Its effectiveness in preventing pregnancy is over 99%, making it one of the most reliable reversible contraceptive methods available. It is a good option for individuals who want long-term birth control and do not wish to become pregnant in the near future.

Potential side effects can include changes in menstrual bleeding patterns, such as lighter periods, spotting, or no periods at all. Some users may also experience headaches, acne, or breast tenderness. While generally safe, there are some risks associated with IUD insertion, including uterine perforation or expulsion, though these are rare. It is important to discuss any health concerns or pre-existing conditions with a healthcare provider before opting for a hormonspiralen. Removal is a simple procedure performed by a healthcare professional when contraception is no longer desired.
