Items in AFP with MESH term: Intrauterine Devices
ABSTRACT: The intrauterine device (IUD) is an effective contraceptive for many women. The copper-releasing IUD can be used for 10 years before replacement and is a good choice for women who cannot, or choose not to, use hormone-releasing contraceptives. However, some women experience an increase in menstrual blood loss and dysmenorrhea. The progestin-releasing IUD can be used for five years. It may reduce menorrhagia and dysmenorrhea, although some women have increased spotting and bleeding during the first months after insertion. The ideal candidates for IUD use are parous women in stable, monogamous relationships. Pregnancy, unexplained vaginal bleeding, and a lifestyle placing the woman at risk for sexually transmitted diseases are contraindications to IUD use. Insertion of the IUD can take place at any time during the menstrual cycle provided the woman is not pregnant. Before insertion, a bimanual examination and a sounding of the uterus are necessary to determine the uterus position and the depth of the uterine cavity. The IUD is inserted into the uterus according to individual protocols, with the threads cut at a length to allow the patient to check the device's position. Expulsion may occur with both types of IUDs.
ABSTRACT: The intrauterine device, a common form of birth control in the early 1970s, is now avoided by American physicians and women because of concern about complications. This concern is largely the result of the problems reported with use of an intrauterine device that is no longer manufactured. More recent intrauterine devices have an improved design, and reevaluation has shown them to be a safe, efficacious and cost-effective form of birth control. Careful patient selection and preinsertion counseling are crucial to success with the device. Recent studies conclude that the intrauterine device poses no increased risk of pelvic inflammatory disease or infertility when used by appropriately selected patients.

Intrauterine Devices: An Update - Article
ABSTRACT: Three intrauterine devices (IUDs) are available in the United States: the copper T 380A and two levonorgestrel-releasing IUDs, one that releases 20 mcg of levonorgestrel per 24 hours, and one that releases 14 mcg per 24 hours. All are safe and effective methods of contraception that work predominantly by prefertilization mechanisms. The copper T 380A IUD may be placed in nonpregnant women at any time in the menstrual cycle. The prescribing information for the 20- and 14-mcg levonorgestrel-releasing IUDs advises that insertion occur during the first seven days of menses. Insertion immediately after vaginal or cesarean delivery may be considered with the copper T 380A and the 20-mcg levonorgestrel-releasing IUDs; however, expulsion rates are higher than with delayed postpartum insertion. The prescribing information for both levonorgestrel-releasing IUDs advises a waiting period of six weeks postpartum or following second-trimester pregnancy loss. Current guidelines indicate that IUDs are acceptable for use in nulliparous women, in adolescents, and in women who are breastfeeding. They may also be used in women who have a history of sexually transmitted infection, although screening is recommended. IUDs should not be inserted for at least three months after resolution of a sexually transmitted infection. Neither antibiotic prophylaxis nor misoprostol use before IUD insertion is beneficial. If pregnancy occurs, the IUD should be removed if feasible. Possible side effects of levonorgestrel-releasing IUDs include headaches, nausea, hair loss, breast tenderness, depression, decreased libido, ovarian cysts, oligomenorrhea, and amenorrhea. The main side effect of the copper T 380A IUD is increased menstrual bleeding, which may continue even with long-term use.
