Sometimes a woman needs emergency prevention of pregnancy. But because emergency contraception called the emergency, it can be done only when absolutely necessary, but not used as a permanent way of preventing pregnancy - it can cause a number of significant functional changes in a woman's body.
In some cases, require emergency contraception and how to conduct
Emergency contraception is carried after unprotected sex or when they were violated basic rules of (planned) contraception. This situation can occur if the condom broke, the diaphragm is not fully dissolved in the vagina spermicides (eg, tablet), it was broken pattern of use of combined hormonal contraceptives. Of particular importance is emergency contraception in cases of rape, but it does not protect against sexually transmitted infections.
There are several methods of emergency contraception. Unfortunately, not all of them are equally effective.
Hormonal methods of emergency contraception
Hormonal methods of emergency contraception is the use of pills containing high doses of progestogen - synthetic analogues of progesterone (Postinor eskapel) and the application of the special scheme of combined oral contraceptives.
Postinor and eskapel - it is almost identical preparations with different dosage of the main active ingredient - levonorgestrel. Depending on the dose used, one or two tablets, which dramatically inhibit the secretion of female hormones estrogen, oocyte maturation and its exit from the ovary. Furthermore, under the action of these drugs endometrium is changed so that its introduction into the embryo becomes impossible. If the pills are taken in time (in the first 72 hours after unprotected sex), the high efficiency of the method.
The use of combined oral contraceptives for emergency contraception is held under the supervision of a physician according to a special Yuzpe regimen. Warned oocyte maturation and ovulation. When used properly, it is also an effective way.

The mechanism of action of IUD based on the fact that its constituent copper released into the environment of the uterus and makes it unsuitable for the egg of life. Simultaneously in the uterine wall there is an inflammatory process induced by an infection, and the mechanical stimulation, which also reduces the possibility of growth and development of the oocyte.
This is quite an effective method of contraception, including emergency. But it can be used only if a woman requires not only the job, but also a long (more than five years) protection against pregnancy.
If after a while the woman is planning a pregnancy, after the removal of the spiral fertility in most cases restored almost immediately.
However, in a spiral and it has negative characteristics. Thus, continuous inflammation of the uterine cavity may predispose to introduce infection. Furthermore, IUD may cause menstrual disorder painful with copious bleeding, which in turn may lead to the development of iron deficiency anemia. After removal of the helix increases the risk of ectopic pregnancy. Therefore, a woman who was set IUD should semiannually necessarily be seen by your doctor.
