Which type of IUD has the additional benefit of reducing menstrual bleeding?

The hormonal IUD is recognized for its ability to reduce menstrual bleeding, which distinguishes it from other types of intrauterine devices. This reduction in bleeding occurs as the hormone (progestin) released by the hormonal IUD thins the endometrial lining, making periods lighter and, in some cases, eliminating them altogether after continuous use. This mechanism not only alleviates heavy menstrual bleeding but also provides additional benefits, such as decreasing menstrual cramps and pelvic pain.

In contrast, the copper IUD is known for increased menstrual bleeding and cramping during periods, as the copper creates a local inflammatory response that can exacerbate these symptoms. The concept of a barrier IUD is not standard within the classification of IUDs; rather, barrier methods are typically separate contraceptive devices, such as condoms, which do not provide the same benefits or mechanism as IUDs. The term natural IUD is not commonly used in clinical practice and does not refer to any recognized contraceptive method. Therefore, the hormonal IUD stands out as the premier choice for those looking for both contraception and reduced menstrual bleeding.
