Intrauterine System

What is it?

• A T-shaped device that contains a hormone called levonorgestrel.
• The hormone is released slowly over time and acts on the lining of the uterus.
• It is inserted into the uterus by your physician in the doctor’s office.
• Two threads may be felt in the vagina, so a woman can check for herself to ensure that the IUS is still in place.

How does it work?

• It thickens the cervical mucus making it difficult for sperm to reach the egg.
• It causes changes in the lining of the uterus that helps to prevent implantation.
• In some women, it may prevent the ovary from releasing an egg.
