IUDs give you great, long-term protection against pregnancy — they’re more than 99% effective. They work as well as sterilization and the birth control implant. IUDs are one of the most effective methods you can get because there’s almost no way you can mess it up. You can’t forget to use it (like the pill or ring), or use it incorrectly (like condoms). IUDs are “set-it-and-forget-it” birth control.
Once your IUD is in, you barely have to think about it — it works until it expires or you have it taken out. That means no trips to the pharmacy, no pill to take or ring to put in, and nothing you have to do before sex to prevent pregnancy. Plus you’re protected against pregnancy for 3 to 12 years, depending on what kind you get.
Additionally, a hormonal IUD has other benefits aside from preventing pregnancy. Some of the side benefits of hormonal IUD include Severe menstrual pain and pain related to the abnormal growth of uterine-lining tissue outside the uterus (endometriosis), The risk of pelvic infection, and The risk of endometrial cancer.
