Intrauterine device

From WikiMD's Wellness Encyclopedia

(Redirected from Intrauterine contraceptive)

An Intrauterine Device (IUD) is a small, often T-shaped birth control device that is inserted into a woman's uterus to prevent pregnancy[1]. IUDs are long-term, reversible, and one of the most effective birth control methods available.

Types of IUDs[edit | edit source]

There are two main types of IUDs: copper IUDs (such as the ParaGard) and hormonal IUDs (like Mirena, Kyleena, Liletta, and Skyla)[2]. The copper IUD releases copper into the uterus, which works as a spermicide. Hormonal IUDs release progestin into the uterus, which thickens the cervical mucus to prevent sperm from reaching or fertilizing an egg.

Effectiveness and Side Effects[edit | edit source]

IUDs are more than 99% effective at preventing pregnancy[1]. Side effects can include irregular bleeding, headaches, nausea, depression, and acne. In rare cases, the IUD can puncture the uterus upon insertion or can be expelled from the uterus[3].

History of IUDs[edit | edit source]

The concept of an IUD dates back to the early 1900s. The first effective and widely used IUD was the Grafenberg ring, developed in the late 1920s. Modern IUDs have been in use since the 1960s[4].
