The intrauterine device 'Mirena' is a modern highly effective remedy for unwanted pregnancy.

Modern means of contraception are great. One of the most effective is the intrauterine spiral Mirena. The invention reliably protects from unwanted pregnancy.

How the hormonal system "Mirena" works

The hormonal system of Finnish developers is a means of protecting a high degree of reliability. The intrauterine device "Mirena" is made in accordance with the form of the female organ. The device consists of an elastic part of a cylindrical shape, which is filled with a hormone called gestagen. The substance is similar in its nature to the sex hormone of a woman (progesterone). When a helix is introduced into the body cavity, the gestagen is released in very small doses. It does not spread by blood, but acts locally. The hormone reduces the implantation property of the endometrium. At the same time, the growth of the uterine layer slows down, the egg cell can not attach to it and dies.

The hormone, placed in the spiral Mirena, resists penetration of spermatozoa into the uterine cavity. Slime on the neck of the organ becomes more viscous. The gestagen also reduces the mobility of the "male" cells. Such properties contribute to reliable protection against unplanned pregnancy. There are times when pregnancy does occur. But this happens quite rarely - in two cases out of a thousand. The remedy is valid for five years.

Procedure for introducing a helix

The installation of a hormonal system requires a preliminary examination by a gynecologist. The procedure for administration is absolutely painless. It is carried out after the end of menstruation, during the following week. After childbirth - not earlier than one and a half months. After installing the spiral, dizziness and pain in the lower abdomen can be felt at first. Symptoms go away quickly if the system is properly inserted.

Spiral "Mirena" is not installed in the presence of various diseases of the female organ, breast cancer, liver diseases.

In very rare cases, an intrauterine pregnancy occurs. Therefore, you should consult a doctor if there is a delay in menstrual period more than one and a half months. In addition, it is necessary to undergo an examination with a specialist at least one visit per year. This is also necessary to detect the displacement of the spiral due to contraction of the uterus muscles during the menstrual period.

Influence of the hormonal system on the menstrual cycle of a woman

In most cases, when you enter the uterus of the spiral Mirena, menstrual blood is released in a smaller volume than before. Women suffering from heavy secretions are a significant plus. Do not be frightened by copious monthly ones at the first time after installing the system. With time, the amount of excreta is normalized. In 20% of cases, menstruation ceases altogether. In this case, the ovaries continue to function normally.
