Mirena spirals - a unique invention of our days, which guarantees a fairly high percentage of protection against unwanted pregnancy. Note that a one-hundred-percent guarantee is given only by the absence of sex life as such. In all other cases, there is always the opportunity to get pregnant - both during interrupted intercourse and during sex with a condom, not to mention other, more dubious methods of contraception.
Mirena spirals are arranged in appearance in the same way as everyone else. At the end, the spiral diverges in a T-shaped antennae, which abut against the uterus, and the vertical end contains a tail that is released into the vagina. The extra end of the tail is cut off for convenience. However, the difference between Mirena is that on the vertical part of the spiral contains a capsule with the hormone levonorgestrel, which is phased out into the uterus. The duration of this mechanism is five years. Therefore, it is for this period that Mirena hormonal spirals guarantee protection against pregnancy. When installing, you should strictly remember the period, so as not to forget to change contraception.
The essence of the Mirena spiral work is that in the uterine cavity, levonorgestrel leads to thickening of the cervical mucus, through which it is very difficult for sperm to get through. Most of them die at the very beginning of the "marathon", and those that achieve the "best performance" are no longer capable of fertilization. In addition, the action of the hormone thins the uterine mucosa, so if we assume that the cell fusion has occurred, attachment will not occur - such an embryo will not sink into the uterus and simply die without nutrition. If the Mirena spiral is removed, and it can be removed at any time, then the possibility of conception is restored and the woman will again be able to have children. A big plus of Mirena is that she acts all five years with equal strength, that is, a woman should not be afraid that by the fourth year the action of the spiral will weaken.
A Mirena spiral is installed , like all spirals, either on the last day of menstruation or after childbirth one and a half months after the examination by a gynecologist. At the reception, the doctor examines the condition of the woman's genitals, determines the condition of the uterus, are there any contraindications to the Mirena spiral. After this, the tube with the spiral is inserted into the uterine cavity, without changing its position, the conductor is withdrawn, thereby leaving the spiral in the right place and in the right position. Antennae, which are excreted into the vagina, are cut to the optimal size. The time required to install the spiral is minimal, so it makes no sense for a woman to free the whole day for the procedure. The administration is painless. Usually, the uterus perceives any spiral as a foreign body, so after installing the spiral, it will try to push it out. This can be accompanied by pain, as during menstruation and no more. To relieve pain, you can use the usual analgesic.
After installing the Mirena spiral, many women note improvements in their well-being during menstruation. The pains become less severe, scarce bleeding, short-term. There is practically no way out of parts of the mucosa. Such changes are due to the fact that the uterine membrane is thinning for the duration of levonorgestrel. Some women after the Mirena spiral do not menstruate at all, although they are capable of reproducing offspring. According to doctors, such conditions are useful for those who suffer from heavy periods, leading to significant loss of blood, iron deficiency anemia, etc.
The advantages of the Mirena spiral are obvious - it reliably protects the body from pregnancy, does not hold in constant fear for an unplanned conception, does not adversely affect the reproductive system, and has a reversible effect.
