Hormonal IUD

What is the hormonal IUD?

A hormonal intrauterine device (IUD), sometimes also called an intrauterine system (IUS) is a small T-shaped plastic device that is inserted into the woman’s uterus to prevent pregnancy. 

It releases hormones into the uterus so that you don’t get pregnant. 

The IUD has a string at the end that helps a woman check that the device is in place. It also makes removal easy

How does it work?

Hormonal IUD releases hormones so you don't get pregnant. 

The ring works in the following ways:

  • It blocks ovulation. This is the release of an egg from the ovaries. Without an egg there is no pregnancy
  • It thickens the cervical mucus. This makes it harder for sperm to reach the uterus and the fallopian tubes.
  • It thins the lining of the uterus. This makes it harder for a fertilized egg to implant in the uterine walls.


How effective is it?

The hormonal IUD is one of the most effective contraceptives available.

Is the hormonal IUD safe?

Many women use the hormonal IUD without any problems. But that isn’t true for everybody. Like every medication, the hormonal IUD carries some risk, and certain conditions might increase the probability of side effects.

It is therefore important to report every condition you have to your doctor. Let him or her evaluate whether the hormonal IUD is the right contraceptive for you.
