There is a long-established saying that children are the flowers of our lives. This is true, but only if they are desired. An unplanned pregnancy, about which women say “it happened”, is unlikely to give them special joy. However, some of them remain pregnant and give birth to an unexpected child, while others decide on an abortion. Of course, everyone has their own independent opinions on this matter, but nevertheless, probably, abortion is not an act to be proud of. Many gynecologists are perplexed to ask why do women take such a step? Isn't it better to think about the consequences in advance and just prevent pregnancy? After all, at the moment there are many different methods of contraception. Each female representative can choose for herself what is best for her, but in this article I would like to dwell in more detail on intrauterine systems.
One of the most common and widely known intrauterine systems is the Mirena spiral. The instructions attached to this spiral indicate the content of the hormone in it. Therefore, it can be used not only as a means of protection from unwanted pregnancies, but also in some other cases. Thus, since the Mirena spiral is hormonal, it can be prescribed as estrogen replacement therapy, for treating menorrhagia, and also for protecting against too rapid proliferation of the uterine lining.
All intrauterine systems guarantee 98% reliability. The contraceptive spiral Mirena is also a very effective, convenient and long-term contraceptive. After installing it, you can forget about the methods of protection for the next 5 years. In addition, this system is made in a T-shape, which helps it more closely match the shape of the uterus.
Let's try to figure out how the Mirena spiral works. Instructions for use describe in detail the effect of levonorgestrel contained in the core of Mirena. The container containing levonorgesterel is coated with a membrane. Through it, its controlled continuous diffusion occurs. Levonorgestrel is released with a constant constant speed in very small quantities, its daily release is 20 μg.
The Mirena spiral prevents pregnancy, controls the development of the uterine membrane and prevents the penetration of sperm into the uterus. Levonorgestrel, which enters the uterine cavity, locally affects the endothermy, preventing polyferative changes in it and reducing its implantation function. Thus, endothermia does not reach the maturity that is necessary for the occurrence of pregnancy. Levonorgestrel also has a small systemic effect, which manifests itself in the inhibition of ovulation in several cycles.
The Mirena spiral helps to reduce the volume of intense menstrual bleeding immediately after 2-3 months of use. The volume of menstrual blood loss decreases by approximately 88%. Some women report a complete cessation of menstrual bleeding. And this, in turn, reduces the risk of iron deficiency anemia. Also, "Mirena" is able to reduce premenstrual and menstrual pain.
However, there are some contraindications in which the Mirena spiral cannot be used. Instructions for its use include the following conditions:
- the presence of cancer of the uterus or cervix, as well as suspicion of it;
- pregnancy or assumptions about its presence;
- abnormalities of the uterus or cervix;
- cervicitis;
- mammary cancer;
- postpartum endometritis ;
- uterine infection due to abortion;
- urinary tract infections;
- intolerance to the components of the spiral.
It must be said that when you purchase the Mirena spiral, you will need instructions only for familiarization, and you can get all the other tips about installing it only after a gynecological examination by a doctor.
