Iud Presence Poses High Risks To Pregnant Women

A number of modern women are using intrauterine device (IUD) as their form of birth control, most doctors say. Mirena is one of the most popular brands of IUD. Mirena is a small, T-shaped, flexible device which is inserted into the uterus to prevent pregnancy. It is a hormone-releasing IUD which makes the uterine linings unsuitable for the sperms. This device is 99.9 percent effective and may be used up to five years. However, when pregnancy does happen despite using an IUD, there may be serious complications to the pregnancy and risks to the mother and the fetus, according to health experts. This article tackles the potentially serious health complications caused by IUD pregnancy.

Ectopic Pregnancy

The use of IUD is considered to be a risk factor for future ectopic pregnancy. Ectopic pregnancy is a medical condition which is often characterized by a fertilized egg which settles and grows in the fallopian tube. The greatest risk factor for an ectopic pregnancy is a prior history of an ectopic pregnancy. The recurrence rate is 15 percent after the first ectopic pregnancy, and 30 percent after the second. A woman, who had a history of ectopic pregnancy, is not recommended to use Mirena IUD as their form of birth control.


When a woman gets pregnant while the IUD is still in place, there is a higher chance of miscarriage. Normally for a pregnant woman without an IUD, the miscarriage rate is about 18 to 20 percent. However, IUD pregnancy raises the risk for miscarriage about 50 percent. However, removing the IUD decreases the risk by 25 percent.

Premature Delivery

Leaving an IUD in place during the pregnancy increases the likelihood of preterm delivery. Women who have IUDs in place during their pregnancies are up to four times more likely to deliver their baby prematurely than women without an IUD in place. Additionally, because of the progestin released by Mirena, should a woman choose to continue her pregnancy with her Mirena IUD in place, the long-term effects on the baby are not yet known.

If you are a woman who is inserted with Mirena IUD and experienced these medical conditions, you need to contact your healthcare provider as soon as possible. The Food and Drug Administration has already released a warning to Bayer, manufacturer of Mirena IUD, due to its over-advertisement but failed to disclose the products potential adverse side effects.
