Copper IUDs

A Copper Intrauterine Device (IUD), also known as an intrauterine coil, is a type of long-term contraceptive device that is inserted into the uterus. It is embedded with copper, a material that contributes to its highly effective birth control properties.

Mechanism of Action

Copper IUDs function by releasing copper ions into the uterine cavity. These ions create a hostile environment for sperm, impairing their motility and viability. This greatly decreases the likelihood of successful fertilization of an egg by a sperm cell. Copper IUDs also induce changes in the uterine lining, making it less suitable for implantation of a fertilized egg.

Effectiveness and Longevity

Copper IUDs are among the most effective forms of reversible contraception currently available, boasting a one-year failure rate of around 0.7%. This means that fewer than 1 out of 100 women will experience an unintended pregnancy within the first year of use. The device is designed to provide birth control for up to twelve years, after which it must be replaced.

Application and Removal

The device is inserted into the uterus by a healthcare provider during an office visit. The process is typically quick, though some women may experience discomfort during and after insertion. Copper IUDs can also be used as an emergency contraceptive within five days of unprotected sexual intercourse to prevent pregnancy.

Fertility usually returns rapidly upon the removal of the device, which can be done by a healthcare professional at any point, making it a reversible form of contraception.

Suitability

Copper IUDs can be utilized by women of various ages, including those who have not had children. They can provide a birth control solution for those who prefer not to or cannot use hormonal methods of contraception due to health reasons or personal preference.
