Mirena is contraceptive device made by Bayer. It is a small, T-shaped piece of plastic, which is inserted into the vagina. Once in place, the device, or intrauterine system (IUS) remains active for 5 years. It works by slowly releasing its contents, which is a synthetic hormone, into the body over a prolonged period. This provides protection against pregnancy in much the same way as the regular pill, or the patch.
- Highly efficient protection
- One time application
- Relief from heavy periods
In the female body, hormones play a big part in getting the reproductive system ready for pregnancy each month. Progesterone regulates when eggs are released and made available for fertilisation, and also manages the build up of lining along the uterine wall. When levels of these hormones dissipate each month, eggs are produced by the ovary, the endometrium develops, and the body is prepared for conception.
Hormonal contraceptives supersede this process. In Mirena, the operating agent is a hormone called levonorgestrel. This works as a substitute for natural levels of progesterone when they fall. The ovaries respond to the presence of this artificial hormone by not producing an egg, so that fertilisation cannot take place. The presence of this hormone also causes the lining of the uterine wall, also known as the endometrium, to remain thin, providing no sufficient purchase for an egg to attach and develop. A third function of this hormone is to thicken cervical mucus, and this stops sperm from being able to get through to an egg as easily.
This treatment is very effective at preventing pregnancy. Its application is a task which will have to be carried by out by a qualified specialist, such as a doctor or family planning nurse; but once it has been inserted, it will provide contraception for as long as 5 years. Sometimes, Mirena is prescribed to reduce discomfort associated with heavy periods (alongside providing contraception), and due to its hormonal qualities, is a useful and effective form of hormone replacement therapy for older women.
