Intrauterine Contraceptive Systems

Intrauterine Contraceptive Systems


There are two types of intrauterine system (IUS) used in Well Woman Centres for long term contraception. Both release progesterone directly into the uterus. The Mirena intrauterine system provides safe effective contraception for 5 years. The Jaydess intrauterine system lasts for 3 years.

Both are small T – shaped devices that must be inserted into your womb by a trained doctor.
