Enhancing Algorithms for the Management of Children Conceived by Assisted Reproductive Technologies Based on a Comprehensive Assessment of the Impact of Modern Methods of Conception on Their Health Status
Research Methods and Ethical Issues
Research Methods:
To achieve the goals of the study, the following stages are anticipated:
Retrospective Analysis of Anamnestic Data:
This stage involves studying the relationship between the physical status and morbidity structure of 300 children under the age of three, who were conceived by advanced ART methods. Additionally, the medical history of their mothers regarding the use of various medications during pregnancy-such as estrogen, progesterone, thyroid hormones, antithyroid hormones, vitamins, microelements, and aspirin-will be examined. To facilitate this analysis, individual registration cards will be developed, approved by the ethics committee, and ratified by the Academic Council. The data will be submitted using Google Forms, followed by the inclusion of copyright information into the state register.
Evaluation of Anthropometric Data:
This stage will assess the anthropometric data of 300 children under three years of age, focusing on those born after FET or fresh embryo transfer (Fresh-ET). Measurements will include weight, height, and head and chest circumference at the time of examination. Measurements for children under one year will utilize scales with a pan balance, a horizontal stadiometer, and a measuring tape. For children over one year, floor electronic scales, a vertical stadiometer, and a centimeter tape will be employed. Birth anthropometric data will be sourced retrospectively, while the WHO Child Growth Standards will be utilized to evaluate weight, height, head, and chest circumference relative to age and gender.
Study of Psychomotor Development:
The psychomotor development of the 300 children under three years of age conceived via IVF or ICSI in fresh or frozen cycles will be assessed. This evaluation will employ standardized instruments such as the R. Griffiths Mental Development Scale and Denver Developmental Screening Tests. For children under one year, neurosonography will be conducted to assess brain structures, and retrospective results for children over one year of age will be extracted from medical records.
The assessment aims to determine the functions of the nervous system utilizing the aforementioned standardized scales, focusing on various developmental parameters, including motor skills, social adaptation, communication abilities, and play skills. Scores will be compiled to ascertain overall developmental levels. The Denver II developmental screening test is specifically designed to assess children from birth to six years of age. It enhances diagnostic capabilities and evaluates several critical parameters, including: 1) personal and social characteristics, which examine the child's interactions with others and their ability to meet personal needs; 2) the development of gross and fine motor skills; 3) the development of both motor and sensory speech; and 4) an assessment of the child's behavior during the evaluation process.
In cases where children are identified as being in the "risk group," a consultation with a neurologist is planned to establish examination protocols and identify the etiopathogenetic basis for potential developmental disorders. Standard methods of neurological examination will be utilized to assess the development of motor, sensory, cognitive, speech, emotional, communicative, and behavioral parameters in conjunction with anamnestic data and the overall state of somatic health.
Assessment of Reproductive Health:
The study will also evaluate the effect of ICSI, particularly in cases of male infertility, on the reproductive health and development of 200 male children under three years of age, in comparison with children conceived via classic IVF. This evaluation will involve objective examinations conducted by a pediatric andrologist to investigate the prevalence of urogenital pathology, supplemented by ultrasounds of the scrotum, kidneys, and bladder. Additionally, hormonal status will be assessed by Inhibin B and Anti-Müllerian Hormone (AMH). Anamnestic data will be collected to explore the relationship between the reproductive health of fathers and their sons born after ICSI.
3) Methods of Data Collection and Processing Data Collection Sources of Information: Data will be sourced from the International clinical center of the reproductology "PERSONA" and Institute of Reproductive Medicine (IRM clinic), in addition to direct examinations of participants based

2.3. Project Tasks:
To attain the overall project goal, the following tasks must be addressed:
Rationale for Objectives:
Following the completion of the project and the fulfillment of all designated tasks, the technological readiness level is anticipated to be 2. It will be attributed to the project's scientific and technical outcomes, which include the creation of a predictive model and the establishment of general principles for the care and management of children conceived by IVF or ICSI, utilizing either fresh or frozen cycles. Additionally, the project aims to publish articles based on the findings of applied research in peer-reviewed scientific journals that are indexed by international citation systems.
3. Scientific Novelty and Significance of the Project
Prerequisites for Project Development. The scientific novelty and significance of this project stem from the increasing acceptance and utilization of IVF as a viable method for addressing infertility. The enhanced accessibility and success rates of IVF procedures, coupled with socio-demographic trends such as delayed parenthood, have resulted in a substantial rise in the number of children born after ART. The provision of reimbursed 7,000 IVF cycles annually in Kazakhstan highlights the government's considerable focus on addressing infertility issues. Nevertheless, despite advancements in ART, the implications of advanced reproductive techniques on the health of offspring remain inadequately explored. Over recent decades, ART has experienced considerable evolution, paralleling developments in reproductive medicine. The adoption of FET and ICSI techniques has escalated significantly, raising concerns regarding their potential impact on offspring health. Research indicates that FET may contribute to the birth of large-for-gestational-age children and is associated with heightened risks of adverse obstetric and perinatal outcomes, as well as respiratory, infectious, and neurological disorders.
Given the critical role of the sperm epigenome during early embryogenesis, it is imperative to scrutinize the consequences of utilizing sperm from men with infertility in ICSI procedures. Consequently, there is an increasing focus on the health status, endocrine, and reproductive profiles of boys and young adult males who were conceived by ICSI. While the literature has extensively documented the growth and overall health of children treated with ICSI, there is limited information regarding the gonadal function of these male offspring. Reports indicate occurrences of elevated genital malformations, diminished testosterone levels, and abnormal levels of Inhibin B and follicle-stimulating hormone (FSH) in boys conceived through ICSI. Inhibin B is pivotal in regulating the hypothalamic-pituitary-gonadal hormonal axis during childhood and measuring its serum levels in boys may provide significant clinical insights into potential deficiencies in gonadal development that may not manifest until puberty or later stages of life.
Numerous studies underscore the potential association between prolonged use of high doses of hormonal medications in IVF programs and the emergence of metabolic disorders in offspring, including insulin resistance and prediabetes. Furthermore, there is an increased risk of inflammatory conditions in children, which may present as a higher incidence of infectious diseases during early childhood. An additional critical consideration is the impact of medications administered for concomitant conditions in women undergoing IVF. For instance, the use of antithyroid medications during early pregnancy has been consistently linked to an elevated risk of congenital anomalies. The mechanisms underlying the teratogenic effects of these agents require further investigation, although they are presumably related to disruptions in thyroid hormonal regulation during pivotal stages of embryogenesis. Concerns have also been raised regarding the potential increase in the risk of malformations associated with dydrogesterone in the first trimester of pregnancy; however, further research is necessary to substantiate this correlation and elucidate the dose-dependent nature of the effect.
The influence of ART on the neurodevelopmental outcomes of offspring warrants particular attention. The current literature reveals a dearth of specific studies assessing long-term cognitive, behavioral, and mental health effects in children conceived by ART, thus limiting our comprehension of possible repercussions. Moreover, there is a notable prevalence of perinatal complications in children born after ART, including hypoxic-ischemic brain injury and pathological hyperbilirubinemia, which may significantly affect the child's future health and development.
Justification of Scientific Novelty Existing data are limited but suggest that modern techniques, paternal infertility, and maternal pharmacological interventions during gestation may contribute to certain adverse health outcomes in offspring. The objective of our project is to address these gaps by conducting a study that encompasses innovative assisted reproductive techniques and assesses not only the physical and neuropsychiatric outcomes but also the reproductive health of children born after ART in Kazakhstan. The findings from this investigation will enhance understanding of the implications of utilizing advanced techniques, thereby facilitating improvements in ART guidelines, clinical practices, and the mitigation of potential risks to offspring, as well as the development of management algorithms. The proposed study of a cohort of children in Kazakhstan has the potential to significantly augment the existing database and enhance the reliability of the findings, allowing for more generalized conclusions that may be applicable at a global level.
The novelty of this study lies in its comprehensive analysis of the effects of advanced ART methods, including ICSI and FET on the health status and development of offspring. By examining the somatic, neuropsychological, and reproductive health of children conceived by these methods, the research offers new insights into the potential risks and outcomes linked to ART.
4) Impact of the Project This project, which is dedicated to the long-term examination of the implications of advanced ART methods on offspring health, holds significant socio-economic relevance for Kazakhstan. Its scope transcends mere medical inquiry, addressing fundamental aspects of national well-being. The recommendations developed through this project for optimizing ART guidelines and implementing postnatal monitoring for children conceived via advanced technologies will have practical applications within Kazakhstan's healthcare framework. This initiative will facilitate the timely identification and effective treatment of potential pathological conditions, thereby reducing morbidity and mortality rates among children conceived by ART.
Furthermore, the emphasis on early diagnosis and preventative measures has the potential to substantially lower the costs associated with long-term treatment and rehabilitation. The anticipated economic benefits will also alleviate pressure on the healthcare system. The importance of this project extends beyond the medical realm; it exemplifies Kazakhstan's commitment to investing in scientific research and advancing healthcare development, which is essential for enhancing the quality of life for its population and bolstering the country's reputation on the global stage.
The findings of this study will be disseminated widely among the medical community and the public, thereby enhancing awareness of ART and improving the reproductive health landscape. The successful completion of this project will serve as a model for other nations seeking to refine their reproductive health systems and elevate the standard of healthcare for all citizens. Additionally, the data generated may be instrumental in formulating national programs dedicated to reproductive health and offering support for families with children conceived by ART. Ultimately, this initiative contributes to the social well-being and economic development of Kazakhstan, ensuring a healthy future for subsequent generations.
