Abstract Confusion concerning a child’s genetic identity is a common objection to the application of novel technologies to human embryos. Unsurprisingly then, concern for genetic identity has been used to justify successive waves of regulatory activity and is again appearing in debates about regulatory responses to emerging reproductive technologies. By examining the history of Australian law’s understanding and responses to so-called genetic identity in the context of past and current scientific developments in reproductive technology, this paper investigates regulatory reform needed for still emerging reproductive technologies. While this paper presents and analyzes in some detail Australian regulation and the policy deliberations and scientific developments that led to them, the identified inconsistencies in the regulatory responses, and recommended reforms to address emerging reproductive technologies offered, address issues relevant to many countries responding to the same technologies.

Introduction. The use of  sisted reproductive technologies has had sufficient experience to reduce the risks associated with the technologies themselves. But pediatricians remain concerned about the health of children born from induced pregnancies because of the influence of the parents’ initial health on perinatal outcomes. Congenital malformations remain socially significant, the risk of which may be higher for children from induced pregnancy.Objective: to evaluate the effect of initial parental health and the methods of assisted reproductive technology used on the formation of congenital malformations and minor anomalies in children from singleton induced pregnancies.Materials and Methods. A retrospective cohort study was conducted using data on live-born children from singleton induced pregnancy born at the Avicenna Medical Center (Novosibirsk) over the period from 2007 to 2017 (n = 409). The reproductive, somatic, and infectious history of the parents and the methods of assisted reproductive technology used were assessed. Parental fertility treatment up to childbirth was performed in the same center, which ensured complete continuity of follow-up. Differences between the groups of children from SIP with and without congenital anomalies were determined using Pearson’s chi-squared test.Results and discussion. We found that children with congenital malformations and minor anomalies were more often born as a result of subsequent pregnancies; thawed embryos transferred at the blastocyst stage were used in assisted reproductive technology programs (p < 0.05); exacerbations of herpes type 2 infection were diagnosed during the current pregnancy (p < 0.05). In the group of children with only CM, the parents had a longer history of infertility (8.3 ± 1.2) years; pregnancy was achieved by transferring fresh embryos at the blastocyst stage (in 68.2% of cases). In the group of children without congenital malformations and minor anomalies, the maternal infectious history was more severe: there were significantly more frequent cases of urogenital infections (p < 0.05) and exacerbations of herpes simplex virus type 1 during pregnancy (p < 0.05).Conclusion. A set of measures aimed at an earlier solution of the infertility problem is necessary for the primary prevention of congenital abnormalities associated with the age and duration of parental infertility.

Developmental Dynamics

In order to estimate the diversity of embryo cleavage relatives to embryo progress (blastocyst formation), time-lapse imaging data of preimplantation human embryo development were used. This retrospective study is focused on the topographic features and time parameters of the cleavages, with particular emphasis on the lengths of cleavage cycles and the genealogy of blastomeres in 2- to 8-cell human embryos. We have found that all 4-cell human embryos have four developmental variants that are based on the sequence of appearance and orientation of cleavage planes during embryo cleavage from 2 to 4 blastomeres. Each variant of cleavage shows a strong correlation with further developmental dynamics of the embryos (different cleavage cycle characteristics as well as lengths of blastomere cycles). An analysis of the sequence of human blastomere divisions allowed us to postulate that the effects of zygotic determinants are eliminated as a result of cleavage, and that, thereafter, blastomeres acquire the ability of own syntheses, regulation, polarization, formation of functional contacts, and, finally, of specific differentiation. This data on the early development of human embryos obtained using noninvasive methods complements and extend our understanding of the embryogenesis of eutherian mammals and may be applied in the practice of reproductive technologies.

This paper provides an analysis of how cultural notions of the body and kinship conveyed through Western medical technologies and practices in Assisted Reproductive Technologies (ART) bring together India's colonial history and its economic development through outsourcing, globalisation and instrumentalised notions of the reproductive body in transnational commercial surrogacy. Essential to this industry is the concept of the disembodied uterus that has arisen in scientific and medical practice, which allows for the logic of the ‘gestational carrier’ as a functional role in ART practices, and therefore in transnational medical fertility travel to India. Highlighting the instrumentalisation of the uterus as an alienable component of a body and subject – and therefore of women's bodies in surrogacy – helps elucidate some of the material and political stakes that accompany the growth of the fertility travel industry in India, where histories of privilege and difference converge. I conclude that the metaphors we use to structure our understanding of bodies and body parts impact how we imagine appropriate roles for people and their bodies in ways that are still deeply entangled with imperial histories of science, and these histories shape the contemporary disparities found in access to medical and legal protections among participants in transnational surrogacy arrangements.

The article represents the results of a prospective clinical and paraclinical examination of women with a history of infertility, pregnancy in which occurred as a result of the assisted reproductive technologies application. The objective: was to study the dynamics of pregnancy features of the psycho - emotional state and the concentration of stress-associated hormones in the serum of pregnant women after the application of assisted reproductive technologies in order to improve the tactics of antenatal care and prevention of obstetric and perinatal complications. Materials and methods. The main group consisted of 80 pregnant women with endocrine infertility, in which pregnancy occurred as a result of therapeutic cycles of ART, control – 50 first-pregnant women with spontaneous fertilization, taken in an arbitrary order of clinical, statistical and laboratory and instrumental studies. In pregnant women of the study groups, in order to determine the psycho emotional state in the screening mode, a clinical interview was conducted by filling out questionnaires that contained the Spilberger test questions in modification of Y.L. Hanina and «Test of relationof pregnant» by the method of I.V. Dobryakova. In the dynamics of pregnancy, the concentration of prolactin (PRL) and cortisol (K) was determined by the enzyme immunoassay on the Reader-MSR-1000 apparatus using test systems manufactured by Hema-Medicament (Russia). Results. Pregnant women with infertility in past history were characterized by a state of chronic stress. According to the results of the Spielberger test in modification Y .L. Hanina every second pregnant of main group had a high level of reactive and every fourth personal anxiety. Almost 90.0% of pregnant women after art are characterized by the presence of pathological PKGD, among which an alarming and depressive type was registered in every sixth and twelfth pregnant woman, respectively. The obtained data are confirmed by the results of the study of the level of K and PRL. For women with a history of infertility and pregnancy, which is the result of therapeutic cycles of ART, inherent in increasing concentrations of stress-associated hormones – cortisol and prolactin, which is one of the reasons for the complicated course of pregnancy and requires reasonable pathogenetic correction. Conclusion. For women who are pregnant as a result of the use of therapeutic cycles of art characterized by a high level of personal and reactive anxiety and PKGD, which confirm the presence of neuropsychiatric and afferent disorders. Increasing the concentration of stress-associated hormones is one of the causes of complicated pregnancy and requires a reasonable pathogenetic correction. Key words: pregnancy, infertility, assisted reproductive technologies, psychological status, cortisol, prolactin.

Cumulus cells are essential during oocytes growth and development, as well as during their maturation and fertilization. Research results have shown that embryo co-cultivation with autologous cumulus cells increases the frequency of blastocyst formation, and also improves the effectiveness of ART programs. Embryo transfer in such programs is recommended to be carried out using the CAT technology (Cumulus-Aided embryo Transfer), which includes embryo cultivation on a layer of cumulus cells and embryo transfer with a certain amount of diluted cumulus cells. Patient G., 38 years old, came to the department with infertility for 15 years and recurrent implantation failure in history. The patient had ART program with autologous co-cultivation of embryos with cumulus cells and a new CAT transfer technology. The patient fell pregnant and gave birth to a healthy child. Autologous cumulus cells can be a source of biologically active substances and improve embryological parameters and implantation rate in ART programs. Embryo co-cultivation with cumulus cells is especially important for patients with recurrent implantation failure. This technique can become an alternative for optimizing human embryos culturing.
