The intrauterine device Mirena, which women establish for themselves, allows 98-99% to protect themselves from unwanted pregnancy. The remaining 1-2% is influenced by factors such as improper initial installation, as well as spontaneous loss of the spiral. The intrauterine device Mirena is the latest science achievement in this area. It is here that two methods of contraception are used for the first time , namely, intrauterine and hormonal. A hormone called levonorgestrel is specifically introduced into this spiral. This spiral, like everyone else, has a T-shape, in the core itself is a hormonal drug.
After the intrauterine device is installed, a gradual release of this hormone occurs from the rod. Intrauterine devices Mirena, you need to install in the period from the first to the seventh day of the menstrual cycle. As before installing an ordinary spiral, it is necessary to consult with a specialist. The price of intrauterine devices Mirena is slightly higher than ordinary, but due to its higher reliability and service life, which is extended to 5 years, it wins in many ways against similar instances.
The principle of action of intrauterine contraceptives.
After installation of the spiral, it creates a reliable obstacle for the egg during its movement along the fallopian tube and mechanical destruction of the egg occurs. Also, the spiral does not allow the egg to attach to the endometrium. Helix contraceptive Mirena cause thickening of cervical mucus, which is an additional factor in protecting against unwanted pregnancy.
It should be said that a small percentage of women, about 2% of all who use intrauterine devices, respond negatively to them. Most often these are the women who use them for the first time. Some of them may have abdominal or back pain, also headaches, irritability increases, the menstrual cycle may slightly change, that is, it lengthens or shortens. But basically, the reviews about the Mirena spiral are only positive, those women who started using it no longer want to use other types of contraceptives.
Indications and contraindications for the use of intrauterine devices
You can use this type of contraceptive for women who have already given birth and who do not plan to become pregnant in the near future. Also, they should not have any inflammatory processes. None of the manufactured intrauterine devices is suitable for women who have not yet given birth, have any sexually transmitted disease or inflammatory process in the genitals. They are also contraindicated for those women who are allergic to any of the components that make up the spiral or to those who suspect a tumor in the uterus. If women undergo treatment with drugs that affect blood density, have serious heart abnormalities, uterine deformity, or those infected with HIV, they are also not recommended to install an intrauterine device.
If the spiral is correctly selected and installed by a specialist, the possibility of pregnancy, including tubal, is almost completely eliminated. But as already mentioned, it is most effective and safe to use the intrauterine device to women who have already given birth at least once or to those who have had pregnancies.
Intrauterine device installation
This procedure should be carried out only by a specialist and be sure to a medical institution. First, the cervix is exposed and thoroughly flushed with an antiseptic, and if desired, anesthesia can also be performed. After this, the depth of the cervical canal and its direction are determined. Only after that, with the help of a special conductor, the spiral itself is introduced. Then the conductor is removed and threads about 2 centimeters long are left so that in the future it would be easy to remove the spiral.
