Every woman of childbearing age thinks about how best to protect herself from an unwanted pregnancy. As you know, there are many methods, but those that give a large percentage of protection are units. Today we will talk about the Mirena spiral. Reviews allow us to draw conclusions about her as a reliable contraceptive that delivers the least discomfort to both sexual partners. The spiral system resembles the letter "T" 32 mm long. The vertical rod is enclosed in a cylinder-shaped container containing 52 mg of Levonorgestrel. The system itself is made of polyethylene. The contents of the spiral is continuously released from the container and enters the female body in an amount of not more than 20 micrograms per day. Thus, having established the spiral once, a woman can not worry about the occurrence of an unwanted pregnancy during the shelf life of the spiral - 5 years.
How it works?
Levonorgestrel inhibits the functional activity of the endometrium, creating obstacles to the successful implantation of an egg, changes the properties of cervical mucus, which becomes too viscous and creates a barrier to the penetration of spermatozoa, as a result, sperm motility decreases, so fertilization does not occur. And all this happens due to the Mirena system installed in the body. The reviews of experts confirm that the contraceptive effect of using this spiral is comparable to the indicators that can be achieved with voluntary surgical sterilization.
This method is most in demand by many women, since it is safe, the effect of the drug is reversible, and you do not need to take contraceptives in pill form daily, and the main advantage is the presence of a therapeutic effect if a woman suffers from heavy menstrual bleeding. Even with small fibroids, this spiral can be used. It is recommended to enter it into the body on the first or seventh days of the menstrual cycle, and for women with amenorrhea - on any day.
However, there are side effects that are detected in some patients while using the Mirena spiral. Reviews indicate that the first 4 months the active substance in the reservoir can affect the general condition of a woman, causing headaches, a sharp change in mood, acne, mastalgia, and nausea. In addition, according to statistics, in 12% of patients, examination revealed functional ovarian cysts, which subsequently regressed on their own.
Possible occurrence of menstrual irregularities after installing the Mirena system. Reviews confirm that in most cases these disorders occur very rarely, in the first six months, and are associated with the appearance of intermenstrual uterine bleeding, meager menstruation, amenorrhea, etc. In most cases, these symptoms subsequently disappear.
