IUS is short for Intra Uterine System, a relative new and very reliable method of birth control. It’s a T shaped plastic device with a reservoir of hormones. It looks like an IUD.
It’s inserted into the uterus by a physician.
It continuously releases a small amount of progestagen. It’s functioning is comparable to oral contraceptives.
One type of IUS is Progestasert, which must be replaced every year. Another type is Mirena, which can remain in place for 5 years.
This method is not recommended for girls because insertion is more difficult than an IUD. Normally it’s used by women who have gone through childbirth.
It’s recommended for women with heavy and severely painful periods, since it thins the lining of the womb, making periods shorter and lighter. Sometimes they stop altogether.
