There are a great many modern contraceptives . One of the most effective is the Mirena intrauterine device. The invention protects against 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 shape of the female organ. The device consists of an elastic part of a cylindrical shape, which is filled with hormone - gestagen. The substance is similar in nature to the female sex hormone (progesterone). When a helix is inserted into the organ cavity, 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. In this case, the growth of the uterine layer slows down, the egg cannot attach to it and dies.
The hormone placed in the Mirena spiral resists sperm penetration into the uterine cavity. The mucus on the neck of the organ becomes more viscous. Gestagen also reduces the mobility of "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.
Spiral insertion procedure
The installation of the hormonal system requires a preliminary examination by a gynecologist. The administration procedure is absolutely painless. It is carried out after the end of menstruation, during the next week. After childbirth - not earlier than one and a half months. After installing the spiral, dizziness and pain in the lower abdomen may occur for the first time. Symptoms quickly disappear with the correct introduction of the system.
The Mirena spiral is not established in the presence of various diseases of the female organ, breast cancer, and liver diseases.
Side effects
Possible side effects go away quickly. These include: pain in the lower back and lower abdomen; headaches; the appearance of acne; the formation of ovarian cysts; weight gain; mood swings; decreased libido; itchy skin; rash of allergic genesis; breast tenderness. In very rare cases, an intrauterine pregnancy occurs. Therefore, you should consult a doctor if there is a delay in menstruation for more than one and a half months. In addition, it is necessary to have 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 muscles of the uterus during the menstrual period.
The effect of the hormonal system on a woman’s menstrual cycle
In most cases, when the Mirena spiral is inserted inside the uterus, menstrual blood is released in a smaller volume than before. Women suffering from copious discharge is a significant plus. You should not be afraid of heavy periods during the first time after installing the system. Over time, the amount of discharge normalizes. In 20% of cases, menstruation ceases altogether. In this case, the ovaries continue to function normally.
