Hormone Releasing Intrauterine Devices (IUDs), often referred to as hormonal IUDs, are a form of long-acting reversible contraception (LARC) that is inserted into the uterus to prevent pregnancy. These IUDs are characterized by their ability to release synthetic hormones that have contraceptive effects.
Hormone Releasing IUDs typically come in a T-shaped plastic frame, the arms of which contain a reservoir containing synthetic hormones. A healthcare professional inserts the device into the uterus, where it remains in place for an extended period, typically three to five years depending on the specific model.
The synthetic hormones released by these IUDs primarily include progestin, a synthetic form of the hormone progesterone. Progestin works to thicken cervical mucus, making it difficult for sperm to reach the egg, and also helps to thin the uterine lining, reducing the chance of implantation if fertilization occurs. In some cases, hormone-releasing IUDs may also have a slight inhibitory effect on ovulation, further decreasing the likelihood of pregnancy.
These IUDs are highly effective at preventing pregnancy, with failure rates of less than 1%. They serve as a convenient contraceptive option for women as they do not require constant maintenance like daily pills. Additionally, hormone-releasing IUDs have been found to have additional non-contraceptive benefits, such as reducing menstrual bleeding and relieving menstrual pain in some cases.
It is important to consult with a healthcare provider to determine if this contraceptive method is suitable and safe for an individual based on their specific medical history and needs.
