Intrahepatic cholestasis of pregnancy (idiopathic jaundice of pregnancy, recurrent familial jaundice of pregnancy) is a benign familial disease manifesting itself in the gestational period in itching and (or) jaundice. As a rule, the disease is observed in the 3rd trimester of pregnancy, that is in the 28th-30th week, and may disappear by itself a few days after labor and recur during future pregnancies.The aim of this research is to study the role and factors of vascular homeostasis regulation in women with infertility treated with assisted reproductive technologies (ART) and with concomitant intrahepatic cholestasis. Intrahepatic cholestasis is characterized by the damage of endothelial cells of hepatic sinusoids, changes in the intrahepatic hemodynamics, increased production of cytokines and free radicals. The processes of angiogenesis in the liver are also closely connected with the functional capacity of endothelium. The L-arginine level in blood was measured using the photometric method based. The homocysteine level was measured by the enzymatic cycling method. To measure the level of placental growth factor (PGF) in blood plasma samples, we used the immunochemical method.The research has found especially severe complications in the course of pregnancy after ART in those women with intrahepatic cholestasis whose placentas developed under the conditions of endothelial dysfunction from the very beginning of pregnancy.So, these factors may be early prognostic markers of severe obstetrical and perinatal disorders in women with induced pregnancy and hepatobiliary disorders.

We can assume a deterioration in the psychoemotional state and a decrease in the quality of life in women after assisted reproductive technologies (ART) with intrahepatic cholestasis of pregnancy (ICP), but no scientific information was found on this issue. The objective: to assess the psychoemotional state of pregnant women with ICP after using ART. Materials and methods. We examined 40 pregnant women after ART with the manifestations of ICP (main group) and 40 – without the manifestations of ICP (comparison group). The presence of vegetative dysfunction syndrome was assessed (according to A.M. Wayne); quality of sleep, especially falling asleep and waking up (A.M. Vein, Yu.I. Levin); anxiety level using the test Spielberg in the modification by Hanin, the presence and severity of depression on the Beck scale; quality of life according to the questionnaire SF-36. The data were processed by methods of variation statistics. Results. In pregnant women after ART with ICP, the total number of points on the A.M. Vein questionnaire is 3.5 times higher than the threshold value of 15 points (median 52 [45, 60] points versus 36 [28; 45] points in the absence of ICP, p<0.05). 80.0% of these women reported sleep disorders. The incidence of significant sleep quality disturbances is 37.5%. Patients demonstrate a higher median level of both personal and situational anxiety. Manifestations of depression were noted in 55.0% patients against 27.5% in the comparison group (p<0.05). Women with ICP have lower ratings for their quality of life, both on physical and psychological health scales. The decrease in the integral indicator of physical health (70 [58; 89] versus 84 [75; 92], p<0.05) is a reflection of the physical discomfort associated with ICP. Conclusions. After using ART, women with ICP need to assess the vegetative and psychoemotional state, correct the revealed disorders to normalize the quality of life, and achieve positive perinatal outcomes. Keywords: assisted reproductive technologies, intrahepatic cholestasis of pregnancy, vegetative dysfunction syndrome, anxiety, depression, quality of life.

The oocyte is the major determinant of embryo developmental competence in all mammalian species. Although fundamental advances have been generated in the field of reproductive medicine and assisted reproductive technologies in the past three decades, researchers and clinicians are still trying to elucidate molecular factors and pathways, which could be pivotal for the oocyte’s developmental competence. The cell-to-cell and cell-to-matrix communications are crucial not only for oocytes but also for multicellular organisms in general. This latter mentioned communication is among others possibly due to the Connexin and Pannexin families of large-pore forming channels. Pannexins belong to a protein group of ATP-release channels, therefore of high importance for the oocyte due to its requirements of high energy supply. An increasing body of studies on Pannexins provided evidence that these channels not only play a role during physiological processes of an oocyte but also during pathological circumstances which could lead to the development of diseases or infertility. Connexins are proteins that form membrane channels and gap-junctions, and more precisely, these proteins enable the exchange of some ions and molecules, and therefore they do play a fundamental role in the communication between the oocyte and accompanying cells. Herein, the role of Pannexins and Connexins for the processes of oogenesis, folliculogenesis, oocyte maturation and fertilization will be discussed and, at the end of this review, Pannexin and Connexin related pathologies and their impact on the developmental competence of oocytes will be provided.

Age is perhaps the most important single variable influencing outcome in the assisted reproductive technologies (ART). The effect of advancing age on clinical ART outcome is manifested not only in the pattern of ovarian response to stimulation regimens, but also in reduced implantation efficiency and an increased spontaneous abortion rate. The clinical importance of these factors is compounded by the fact that increasing numbers of older women are presenting for ART treatment. Delayed childbearing is becoming increasingly common in the western world. The availability of methods of birth control, educational and career priorities for women, and the increased rates of divorce and remarriage are some of the factors contributing to this phenomenon.

This article is devoted to the assessment of the role of ALK5 in the profile of early reproductive losses in the use of assisted reproductive technologies, in particular, by using immunohistochemical study in the group of patients with early spontaneous abortion after the procedure of embryo transfer, a lower level of ALK5 expression in the decidual tissue was revealed (in comparison with control), which may be related to the occurrence of early reproductive losses caused by the imbalance in Th1 / Th2 and its effect on the increase in the concentration of natural killer cells.

During the last decade, the availability of next-generation sequencing-based approaches has revealed the presence of microbial communities in almost all the human body, including the reproductive tract. As for other body sites, this resident microbiota has been involved in the maintenance of a healthy status. As a consequence, alterations due to internal or external factors may lead to microbial dysbiosis and to the development of pathologies. Female reproductive microbiota has also been suggested to affect infertility, and it may play a key role in the success of assisted reproductive technologies, such as embryo implantation and pregnancy care. While the vaginal microbiota is well described, the uterine microbiota is underexplored. This could be due to technical issues, as the uterus is a low biomass environment. Here, we review the state of the art regarding the role of the female reproductive system microbiota in women’s health and human reproduction, highlighting its contribution to infertility.
