Considering a Copper IUD?

Updated: Jul 29, 2023

Benefits of the Copper IUD

Copper IUDs are often used by individuals who want to avoid hormone-based contraception. This includes transgender males who may be undergoing hormone therapy as well as any woman who has experienced adverse effects associated with hormone-based contraception. Studies have also suggested that the copper IUD is less likely to lead to endometrial inflammation and immune activation, meaning it is less likely to be rejected by the body than a hormonal IUD.

Disadvantages of the Copper IUD

Overall, the number of adverse effects associated with the copper IUD are low. The most common reasons for the discontinuation of this method are severe menstrual bleeding and dysmenorrhea. Studies have also found a significant relationship between copper IUDs and sexual desire. In one study, 18.3% reported a decreased interest in sex while using a copper IUD.

If you do decide to get an IUD, make sure you ask the right questions and voice all of your concerns with your doctor in advance of your appointment.
