In our time, more couples who are diagnosed as "infertility" do not want to give up and give up the dream of continuing their kind. To help them come gynecologists, andrologists, as well as doctors - reproductologists, able to defeat even absolute infertility with the help of assisted reproductive technologies, such as IVF, ICSI, IMSI, PGD. The most popular among patients are ICSI and IVF - what is their difference?

Who will help


If a couple does not get pregnant within 1 year of trying - this is an occasion to visit a reproductive health expert. "Responsibility" for the non-occurrence of pregnancy is not only and not so much on a woman - in every third pair of "guilty" man. It is for these patients that the branch of assisted reproductive technologies is developing, which includes methods of IVF and ICSI.

What common

Both procedures are performed in several stages. They can be held only after a thorough examination of both partners. Then, with the help of medications, ovulation is stimulated. The resulting egg is seized with the help of a puncture, fertilization is carried out, after which the embryo formed is placed into the uterus.

What is IVF?

The essence of this method is that fertilization is performed outside the female body, for which prepared oocyte oocytes and male seed material are taken. Their connection is carried out in a "test tube" - special laboratory conditions. The transfer of the fertilization process beyond the limits of the female body makes it possible to level out a possible pathological process in it, which does not allow the egg to get its spermatozoon. This method is indicated for obstruction or complete absence of fallopian tubes and some other conditions.


The further algorithm, according to which the IVF procedure should be performed, is that it is necessary to wait for the moment when a fertilized egg will begin to divide, after which the embryo is transferred to the nutrient medium, where it grows well and develops. After 2-3 days, it is placed in a special pocket in the womb of the future mother. If all manipulations will occur competently and on schedule, the developing pregnancy will not differ from the natural one in any way.

What is ICSI?

Decoding ICSI - Intra Cytoplasmic Sperm Injection - sounds like an "intracytoplasmic injection (injection)." This method assumes a strict selection of spermatocytes from the existing male seed in order to identify the most morphologically perfect, highly mobile sex cell (occasionally take several, for every happening).

When the first action is completed, the time of fertilization comes. It is carried out by a special needle-like device made of surgical glass. Preliminarily fixing the egg on the microprimer, in its cytoplasm is introduced immobilized sperm. After fertilization, similar to the IVF procedure, the embryo is transferred to the uterus, where pregnancy develops.

The main reason to apply the ICSI technology is diagnosed male infertility, manifested in the inferiority of spermatozoa, the minimal percentage of spermatozoa and the high degree of their damage. In such a seed material, a low level of sperm vitality is determined.

ICSI and ECO: what is the difference

The most important difference of these techniques is in what sperm will produce the fertilization of the egg. In a simple IVF, this can be done by any of the ejaculated ones, and with ICSI, conception only performs a strict genetic selection.

When female infertility is detected, IVF is prescribed, and in the presence of a male factor without ICSI, pregnancy is unlikely to occur.

During the ICSI procedure, more highly skilled labor of embryologists and micro-instruments is spent, so the cost of such a procedure is higher generally.

Since with IVF the choice of the fertilizing sperm is similar to the natural one, i.e. granted to the occasion, and with ICSI selection is conducted by a specialist, in the second case the percentage of pregnancy is more tall.

The conclusion: what doctors will advise

Given the differences between the two reproductive technologies, which one is preferable? Practitioners advise first to identify the cause of infertility. For those who do not want to have a baby at all, it is recommended that they decide on both these procedures "ECO plus ICSI" in order to exclude the impact of negative factors (including the elderly age of women and immune diseases in men, as well as the deterioration of the quality of sperm a day change). Such a package of reproductive services in clinics is designated as "all-inclusive" and also involves pre-implantation diagnostics of genetic material.
