    Abstract:
    UNLABELLED: Occurrence of pregnancy after in vitro fertilization depends of two components: functional adequacy of the embryo at the blastocyst stage and receptivity of endometrium, which, according to modern perception, are determinate in achieving optimal conditions of implantation. From the pregnancy occurrence point of view, as well as in regard to its further development , implantation is the most crucial phase of IVF/ICSI and ET. As the same time, this phase is also the most vulnerable. Multiple researches have proven the role of mother thrombophilia for genesis of gestation complications and early embryo losses, but in relation to this problem i the context of IVF there is still a lot to be detailed. The objective of this work was to increase the efficiency of IVF and to research the causes of IVF failures, related to thrombophilic genetic mutations and polymorphisms. In order to achieve the set goal 354 women with infertility, who turned to the department of aided reproductive technologies (ART) for infertility treatment by means of IVF, were examined. 237 (66,9%) of women had primary infertility, 117 (33,1%) - secondary infertility. To 228 of these women the IVF (in vitro fertilization) program was introduced for the first time (study group 1), 126 patients had failed IVF history (1 to 9 failed attempts). Patients were 23 to 43 years of age. Obtained results confirm the relation between hemostasis defects, change of hemostasis system activity and efficiency of IVF. CONCLUSIONS: One of the main reason of IVF failure and, probably, of infertility is the hemostasis system disturbance of thrombophilic nature. High correlation is established between the hemostasis system disturbance of thrombophilic nature, preconditioned by genetic mutations and polymorphisms, as well as failed IVFs. Failure of IVF is the indication for expanded examination of genetically determined factors of hemostasis system. In case of presence of genetic defects of thrombophilic nature in hemostasis system the risk of failure in IVF program is 2 and more times higher.
