Background. Embryo cryopreservation is an essential part of ART programs today. In recent years vitrification method is used increasingly widely. Purposes and tasks. To compare the effectiveness of ART programs using vitrified and fresh embryos, as well as different endometrial preparation regimes for frozen\thawed embryo transfer (modified natural cycle (MNC) and the preparatory hormone therapy(PHT)). To analyze the course of pregnancy and perinatal outcomes after vitrified embryo transfer. Materials and methods. We prospectively assessed the ART programs effectiveness and perinatal outcomes in 153 patients (I group), who underwent vitrified embryo transfer in 2011-2013 year. To prepare the endometrium for thawed embryo transfer in 83 patients PHT (Ia subgroup) and MNC in 70 patients (Ib subgroup) were used. Control group consisted of 70 patients, who underwent fresh embryo transfer. Results. The clinical pregnancy rate, birth rate and “take home baby” rate were not significantly different between the I (47,5 %; 30,9 %; 30,9 %) and II (53,0 %; 34,9 %; 32,5 %) groups, and between Ia (48,3 %; 28,4 %; 28,4 %) and IIb (46,6 %; 34,1 %; 34,1 %) subgroups. Complications during pregnancy and delivery, birthweight, length, Apgar score, congenital malformation rate did not differ significantly after vitrified and fresh embryo transfer. Conclusion. Vitrification is an effective method to achieve clinical results, comparable to native cycles. Application of PHT and MNC results in similar clinical outcomes. Transfer Vitrified embryo transfer does not have a negative impact on obstetric and perinatal outcomes when compared with native cycles.

Introduction. A significantly increased frequency of multiple pregnancies including more than two fetuses is a consequence of using assisted reproductive technologies and ovulation stimulations. However, such pregnancies remain poorly investigated. Aim: to study the course and perinatal outcomes of quadruplet pregnancies.Materials and Methods. 7 pregnant women with quadruplets were examined. A comprehensive examination, including fetometry, monitoring of the cervical length, Doppler examination, and treatment of all complications were performed for all pregnant women. Results. Quadruplet pregnancy belongs to the peak risk group for the frequency of multiple gestational complications: cervical incompetence (85.7 %), anemia (71.4 %), preeclampsia (57.1 %), fetal growth retardation (71.4 %), premature birth (100.0 %), massive bleeding during delivery (33.3 %), extremely low birth weight newborns (30.8 %), respiratory disorders (100.0 %), intraventricular hemorrhages (38.5 %).Conclusion. Women with quadruplet pregnancies should be monitored and give a birth in level 3 perinatal centers. Delivery should be preferentially performed by caesarean section. The data obtained additionally underline that as few as a single embryo should solely transferred.

Introduction. The number of women with multiple pregnancy is increasing worldwide, especially in countries with a high level of health care, where assisted reproductive technologies are widely used. According to foreign studies, one third of twins are born as a result of Assisted Reproductive Technologies (ART), so only an increase in multiple pregnancy can be predicted in the future. The main obstetric problem with these pregnancies is the problem of carrying.Objective: To identify the predictors of preterm birth in patients with multiple pregnancy in order to improve monitoring and prophylactic measures among this cohort of women.Material and methods: A retrospective controlled observational study, including 154 patients with multiple pregnancies was carried out. Logistic analysis was used to identify the predictors of preterm labour.Results: The study showed that the predictors of preterm birth varied from one trimester to another. Based on the identified predictors, the predictive models for each trimester of pregnancy were compiled. Most of the identified predictors are related to obstetrical history. Risk groups formation, based on the identification of these predictors, is extremely important for qualified medical support. Prophylactic measures should be performed on the pre-conceptional stage. Pregnancy planning should be recommended only after treatment of chronic endometritis, followed by control of vaginal microflora and progesterone support. It is hardly possible to talk about the prevention of cervical insufficiency. However, cervical correction is an important factor for perinatal outcomes improving. The research suggests that the insertion of cervical pessary in women with multiple pregnancy and cervical insufficiency allows to prolong the gestational period for 7 weeks.Conclusion: a comprehensive approach of management of women with multiple pregnancy based on the prognostic scales of preterm labour, allows to reduce the preterm birth rate.

Purpose: To integrate clinical databases based on the information and analytical systems of medical organizations (MO) and to evaluate outcomes and health of children born by assisted reproductive technologies (ART).Research methods: To form database by integrating information and analytical systems of the medical organizations. To search and unify the data by means of freeware relational database management system (DBMS) – MySQL.Results. A prototype application for the management and support of a unified clinical database to analyze and evaluate the outcomes of ART. To compare information from individual databases of MO one need to match fields in the form of unique personal records, field validation, processing of missing data. Significant (p <0.001) differences in gestational age and anthropometric data in the databases of medical organizations (76% of full-term children from the Automated System “Regional obstetric monitoring” (AS ROM) database compared with 18% according to the IS “Register of Children requiring Early Care”) were determined by the introduction of the conception of ART, along with the presence of perinatal risk factors in children. The created software can be used to create registers of medical organizations, as well as to support clinical decision-making in forecasting, modeling outcomes and children’s health after ART, developing personalized treatment and rehabilitation programs.Conclusion. It is necessary to develop and implement information systems, to create ART registers on the basis of regional and national registers, to analyze the outcomes of the use of reproduction methods.

The expansion of indications for assisted reproductive technology has led to significant implications for assisted reproductive technology (ART) programs worldwide. More than 7 million children in the world were born using ART. Modern clinical practice in the field of reproductive sciences is aimed not only at increasing the effectiveness, but also at the safety of treatment. ART, like any other type of therapy, may be combined with negative side effects. Both the correct prediction of the risks associated with treatment and a personalized approach ensure the absolute safety of infertility treatment using in vitro fertilization. In this regard, over the past decade, a number of new research approaches have been noted that use ART methods integrated into clinical practice: cycle segmentation with subsequent embryo transfer and the elective transfer of one embryo. New approaches provide a control in relation to ovarian stimulation and a reduction in the number of transferred embryos, which helps to minimize primarily adverse perinatal outcomes. Predicting the risks and outcomes of treatment using mathematical modeling is the application of good clinical practice.
