IUD with hormones (intrauterine system)

The IUD with hormones, also called an intrauterine system (IUS), is one of the hormonal contraceptive methods.

It’s a small T-shaped device. The vertical arm of the T is a cylindrical container.

When an IUS is inserted into the uterus, it slowly releases a hormone contained in the cylinder. This hormone thickens the cervical mucus at the entrance to the uterus, which prevents spermatozoa from entering. It also thins the uterine wall. If an ovum is fertilized, it can’t implant and develop. Thus, this kind of IUS provides good protection against unwanted pregnancy.

To get an IUD (or IUS), you’ll need to make an appointment with a doctor for a gynecological examination.
