IUD. IUD stands for Intra-Uterine Device. An IUD is a piece of plastic roughly the size of ones thumb that is inserted through the cervix into the uterus. There it sits and is remarkably effective at preventing pregnancy. The way an IUD works is not fully understood but it is probably a combination of several factors. We do know that just the presence of something in the uterus, IUD or other object such as a uterine septum or fibroid, reduces pregnancy rates. IUDs are inserted during a simple in office procedure by a trained professional. These devices got a bad rep in the 70’s when a couple of specific types were pulled from the market after serious complications were discovered but the type available today has remained one of the safest and most popular methods of birth control world wide. Another benefit of this method is that though it is extremely effective and can be in place for as long as 10 years depending on the chosen brand, it is easily reversible in the office and return to fertility is quick in most cases. IUDs are great methods for women in long term monogamous relationships. If you are interested in this Birth Control Method contact your health care professional to learn more.
