Gynecologist-endocrinologist Evgenia Nazimova told what the Mirena intrauterine hormonal system (IUD) is. It is often referred to simply as a spiral.
— I always get a lot of questions about the Mirena intrauterine hormonal system. Many people want to know how I feel about Mirena. Someone writes that this is a terrible evil, etc., the doctor noted in her blog.
Mirena is a plastic device with a reservoir for the hormone. Its active substance is the hormone levonorgestrel. Released into the uterine cavity, it helps to thicken the mucus of the cervix and thin the inner layer of the uterine wall (endometrium), preventing the penetration of spermatozoa into the uterine cavity, and thereby preventing the fertilization of the egg.
– Its unique feature is a special membrane that allows you to release a strictly specified and very small amount of the hormone daily for 5 years. This is a very high-tech and reliable device that is installed in the uterine cavity by a doctor,– Nazimova wrote.
Indications for installing the Mirena IUD:
Contraception. According to the doctor, now it is “the most effective and hassle-free method of contraception.” You can forget about an unwanted pregnancy for 5 years.
The dose of the hormone that enters the uterine cavity is critically small, but the spiral, the gynecologist notes, is much more effective than birth control pills. This is due to the fact that the hormone acts directly where it is needed.
– But the systemic effect on the body of Mirena is practically reduced to zero, because a meager dose of hormones enters the bloodstream. Therefore, after the installation of the spiral, the woman's ovaries continue to work as usual: ovulation occurs in them, the corpus luteum matures and their own progesterone is produced, – the physician noted. weight and others are unlikely.
Also, indications for the installation of Mirena may be heavy menstruation, bleeding from the uterine cavity, not associated with any pathology, for example: polyps, hyperplasia, etc.
In addition, Mirena can be a component of hormonal therapy for menopause.
