IUD stands for intrauterine device. It’s a small device that’s inserted into the uterus by your health care provider for contraception. Many times IUDs are classified as long-acting reversible contraception (LARC).Almost all women are candidates for an IUD, with a few exceptions. It’s a common myth that women who haven’t been pregnant and who are adolescents aren’t candidates. Pregnancy, age and prior vaginal delivery are not required to insert an IUD. An IUD is an excellent option for women who desire a reversible form of birth control, but don’t desire pregnancy at this time. IUDs are 99 percent protective against pregnancy and don’t require daily compliance.

How do IUDs work?
Currently available IUDs work by preventing sperm from fertilizing ova, although some aspects of the precise mechanism of action are unknown. IUDs are not abortifacients; they don’t interrupt an implanted pregnancy. Pregnancy is prevented by a combination of the ‘foreign body effect’ of the plastic frame and the specific action of the medication (copper or Levonorgestrel) that’s released, which impairs sperm function and implantation, and prevents fertilization.
