In vitro fertilization

IVF

Worldwide, IVF (in vitro fertilization) is considered as the main way to treat infertility. It is effective in any forms. In addition, ECO — often the only way for families in which the sick man.

In vitro fertilization — a relatively new method of treatment of infertility. It was first used in England in 1978. Однако еще 200 лет назад предпринимались подобные попытки.

The essence of the ECO: the sperm meet the egg in a test tube, and then they tended, planted in the womb of a barren woman or a surrogate mother. The favorable outcome of the procedure (the occurrence of pregnancy), there are frequent cases when conceived twins or triplets, because in an attempt to take part in a few eggs. According to the woman's request can be made reduction (removal of excess embryos), but sometimes it leads to death and left to a subsequent miscarriage.

The success of IVF treatment is about 30-35%.

When applied?

IVF is effective in the forms of infertility, when remove the cause of preventing conception is not possible. For example, after ectopic pregnancies, when removed, one or both fallopian tubes, after inflammatory disease, tubal patency when broken and restore it does not seem possible.

When sperm is insufficient or when it few sperm doctors and andrology developed methods for producing sperm artificially by puncture or operation. For male factor infertility are not required to perform IVF, you can simply enter the resulting artificially sperm into the uterus. However, given that this method of obtaining sperm is complex, in this case, the use of IVF gives a greater chance of success.

How often applied?

Unfortunately, the IVF method is used infrequently. The reasons are many:

  • First, this treatment is expensive and not included in the benefits package is available so far for all patients;
  • second IVF centers are subsidized by the state, and little can be found only in major cities.

Survey

If a barren couple turned into a center for the treatment of infertility, the first step will be the examination of both partners. A woman is usually performed ultrasound, blood tests for hormones, tests for AIDS, hepatitis, and syphilis. Man — semen. If necessary, genetic analyzes. Examination takes approximately 2 weeks. After the examination, the decision of which method of infertility treatment is shown each individual pair.

Hormonal treatments

Before IVF woman appointed special hormones that stimulate the growth and maturation of notone or two (As in the ordinary cycle) and multiple follicles. This is necessary, since the procedure is necessary to have a supply of embryos. Woman she makes herself daily injections of hormones. The duration of hormonal treatment is an average of 2 weeks.

Then the woman made puncture of follicles. Procedure on an outpatient basis. Needle through the vagina under ultrasound mature follicles are extracted from the ovaries. Thus, a few eggs. This procedure and low-traumatic complications after it unlikely.

The sperm

If the man is healthy — the difficulty in obtaining the required number of sperm usually does not happen. In cases where spermatogenesis is disturbed, a man in need of special treatment.

There are situations where sperm is produced, but get it the natural way is not possible. Then the doctor performs a puncture. This manipulation is performed under general anesthesia. It is possible to fertilize an egg the one and only sperm.

In vitro fertilization

IVF is carried out directly doctors, embryologists in the embryology laboratory. With the use of modern equipment in special solutions is carried compound of sperm and egg. Through 2-4 day embryos ready for the next step.

Preimplantation diagnosis

Preimplantation diagnosis — a method of research on embryos produced by IVF, before his transfer to the uterus. With the help of modern genetic technologies can be inspected embryo, consisting of only4-8 cells. With the help of this method of diagnosis revealed gross fetal malformations and genetic chromosomal disorders such as Down's syndrome, haemophilia, etc. In addition, with the help of predimplatatsionnoy diagnosis can determine the sex of the child.

Embryo transfer to the uterus

Embryo transfer to the uterus — the simplest procedure of the entire method. Using a special flexible catheter 2-3 fertilized eggs are transferred into the uterus. This does not require anesthesia.

After the transfer of eggs woman can go home to work. No special treatment is required. Nevertheless, in some centers IVF issued sick leave. Naturally, after the procedure is not recommended for women to great physical and emotional stress.

Pregnancy

Pregnancy IVF comes in 30-35% Of cases. Of the 20 pregnancies end in birth an average of 18. After the introduction of embryos once in three days to control the level of hormones in the blood. After 12 days, a pregnancy test is performed. In the case of multiple births at the request of women carry out reduction — removal of "excess" embryos.

Birth

Childbirth pregnancy after IVF are no different from the ordinary. In cases where the cause of infertility — a disease of women, childbirth shall take account of the specific disease. By the method of fertilization, it is not irrelevant.

Children

According to doctors, conceived in a test tube is no different from the rest. However, it is believed that these children do better in school, but more often get sick. Doctors believe that this may be due to the excessive care of the desired child.

The number of IVF attempts

It is known that pregnancy occurs only 30-35% Attempted artificial insemination. The question is: how to be that 70 out of 100 women who did not become pregnant? How many times can you attempt IVF?

In each case, the issue is solved individually. IVF procedure itself is quite safe and can be repeated many times. Some couples pregnancy comes with8-10 attempt. Reasonable limit on the number of procedures is, it is determined by the physician according to the specific situation. In repeated attempts may use embryos not used in the previous time. Unfortunately, the guarantee of pregnancy with IVF one can not give.

Egg donation

When follicular puncture can be obtained more than necessary number of eggs. In these cases, offer healthy women to become donors. Their eggs are used in those cases where the patient does not have its eggs — after removal of the ovaries, the menopause, when the ovaries and other modified

To encourage donations, the woman who agreed to give their eggs, paying less for attempting IVF. Of course, anonymous egg donation, the donor has no rights to a child born out of its egg.

Donated eggs are fertilized by sperm of the husband of the woman, which they are implanted. In this case, the hormone preparation for IVF is not required. В большинстве центров ЭКО лишние оплодотворённые и неоплодотворённые эмбрионы сохраняются в замороженном сос
