Change of a donor egg to the woman for the purpose of further time pregnancy and births of the child as gynecologists-endokrinologi of our medical centre mark, most approaches those patients at whom for various reasons ovaries have been removed or are in strongly damaged condition.

It, in own way, last way to become pregnant from all medical technologies existing for today to which address when even fertilisation in laboratory conditions has not given results.

As a rule, the given procedure is spent with women, and is much more rare - at reproductive age. It is difficult enough process demanding the account of many factors and indicators, however for many it is last chance to become pregnant and give birth to the child. We will tell about change of a donor egg a little bit more in detail.

One of the most important stages of the given procedure consists in a choice of the woman-donor from which eggs will be received. The basic requirement - a good state of health, absence of chronic diseases and gross infringements in the family anamnesis.

As a rule, young women get out, is not more senior 30 - 33 years, it is desirable already having healthy children without any chromosomal anomalies and development infringements.

Use of eggs of relatives of the woman or the anonymous person who has been picked up by special medical service, prosecuting reproductive subjects is possible.

Before eggs for the subsequent fertilisation and change the woman-donor will be taken there passes strict inspection:

- Analyses on a HIV-infection, a hepatitis, infectious and inflammatory diseases of genitals.

- Survey at the therapist, the neuropathologist and some other doctors, depending on features of the family anamnesis.

After doctors have drawn a conclusion on possibility of use of eggs of the woman for change, the special contract in which she refuses any rights to the future child (children) is made, and the pair, on the contrary, incurs all legal responsibility.

Here cost of donor services and feature of payment should be stipulated. Also as the third legal side the medical institution carrying out and supervising all procedure acts, its role too should be registered in the document.

Procedure of extraction of an egg at one woman, its fertilisation in laboratory conditions and changes another has the features.

To begin with it is necessary to synchronise a menstrual cycle of the donor with a cycle of future mother that an embryo without problems a smog be fixed on a mucous membrane of a uterus and develop. For this purpose special medical products are used, in addition to the woman-donor do injections of a stimulating hormone, and to the woman-recipient enter an estrogen preparing a mucous membrane of a uterus to the future pregnancy.

As soon as cycles start to correspond each other and eggs of the donor have reached sufficient degree of a maturity, procedure of their extraction is carried out.

The local anaesthesia operating quickly is for this purpose used, and the special equipment, process passes under the ultrasonic control that does its faster and reliable.

The following stage - fertilisation in laboratory conditions (as a rule, it is used sperm of the partner of the woman-recipient), and embryo transplantation in a uterus cavity.

The mechanism of procedure same, as well as at standard fertilisation, however, as our doctors consider, chance of success all the same a little above because of use healthy eggs of the young woman.

That the embryo was attached to a mucous uterus during two - three weeks it is necessary for woman to accept hormones an estrogen and a progesterone under individually developed scheme.

Preparations can be in the form of tablets, however it is considered to be more effective intramuscular injections. The progesterone should arrive in an organism practically daily as its natural development is considerably slowed down. An estrogen appoint twice or three times a week, depending on a condition and features of functioning of hormonal system of the woman.

Speaking about efficiency of procedure of change of a donor egg, it is necessary to notice, that she gives practically the highest chances to become pregnant and give birth to the child for women after 40 years. More than half of cases terminate successfully from the first attempt, the second increases your chances to become mother even more.

The only thing that can stop pair at use of this technique - rather high cost, reaching time of ten thousand dollars. Here enters both a payment for services of doctors, and the fee of the donor. The price in many respects is contractual, based on many parametres.

Change of a donor egg means, that the impossibility to conceive the child natural by is caused by a condition of reproductive system of the woman, thus man's spermatozoas have high quality.

Unfortunately, sometimes there is an opposite situation and then not so donor egg is required, and donor sperm. Fertilisation in this case can be spent as in laboratory conditions, and внутриматочно. selection of the donor and legal aspect of procedure solve in the same way, as well as in a case with egg change.

You can always pass inspection on possibility of conception and receive a direction in the specialised centre, having addressed to accoucheurs-gynecologists or gynecologists-endokrinologam of our medical centre
