An intra-uterine device (IUD) is a small T-shaped birth control device which is usually made of plastic and wrapped with copper or hormones. This device is inserted into the women’s uterus to prevent pregnancy. A plastic string is tied to the end of the IUD that hangs down the vagina through the cervix. One can check if the IUD is in place by feeling this string. This string is also used by the doctors to remove the IUD.
TYPES OD IUDs:
There are 2 types of IUDs that are usually preferred. They are:
- ¨ Hormonal IUD
- ¨ Copper IUD
The hormonal IUD releases a form of progestin hormone called as levonorgestrel. This type of IUD is found to be the most effective form of contraception than the copper IUDs. They can prevent pregnancy for 3 to 5 years.
The copper IUD is the most commonly used IUD. A copper wire is wound around the stem of the T-shaped device. This can prevent pregnancy for 10 years.
Insertion & working of IUDs:
The insertion of IUD into the uterus is done with help of a specialized doctor. An IUD can be inserted anytime into a women’s body provided she is not pregnant or have a pelvic infection. The insertion procedure takes only a few minutes and sometimes an anesthetic may be given in the area around the cervix.
The main function of the IUD is to prevent the fertilization of the egg by killing or damaging the sperms. The hormonal IUD prevents the fertilization of the egg by killing or damaging the sperms. It makes the mucus in the cervix thick and sticky so that the sperm can’t get through the uterus. It also weakens the uterine lining so that it becomes a poor place for the fertilized egg to implant and grow. The hormone in this IUD also reduces the menstrual cramping and bleeding.
Copper is toxic to the sperm. The copper enables the fallopian tube and uterus to produce a fluid that consists of copper ions, enzymes, white blood cells and prostaglandins that kill the sperms.
What to expect after the treatment and follow-up procedure:
One may experience mild cramping or bleeding after the insertion of IUD. You are not expected to have sex within 24 hours of insertion. You should have a follow-up with your doctor after 4 to 6 weeks of the insertion. Ensure to check the string of the IUD after every period. To do this, insert your finger into the vagina and feel for the plastic string coming out of the cervix. If you cannot feel the string then it doesn’t mean that your IUD has expelled. Sometimes it is difficult to feel the string. There are chances that the string has been pulled up by the cervical canal.
