“…Some articles point to an inverse correlation between the NEB and the income of individuals and households (Arkhan gelskiy et al, 2021;Turner, Robbins, 2023), and others have revealed correlations of different directions when men are compared with women (Fieder, Huber, 2022); it has also been noted that after the division of a cohort into subgroups by income level, the direction of the correlation changes (Co hen et al, 2013;Arkhangelskiy et al, 2021). Demographers pay special attention to the analysis of correlations between the birth rate and educational attainment.…”

The review describes the main methods for assessing directional selection in human populations. These include bioinformatic analysis of DNA sequences via detection of linkage disequilibrium and of deviations from the random distribution of frequencies of genetic variants, demographic and anthropometric studies based on a search for a correlation between fertility and phenotypic traits, genome-wide association studies on fertility along with genetic loci and polygenic risk scores, and a comparison of allele frequencies between generations (in modern samples and in those obtained from burials). Each approach has its limitations and is applicable to different periods in the evolution of Homo sapiens. The main source of error in such studies is thought to be sample stratification, the small number of studies on nonwhite populations, the impossibility of a complete comparison of the associations found and functionally significant causative variants, and the difficulty with taking into account all nongenetic determinants of fertility in contemporary populations. The results obtained by various methods indicate that the direction of human adaptation to new food products has not changed during evolution since the Neolithic; many variants of immunity genes associated with inflammatory and autoimmune diseases in modern populations have undergone positive selection over the past 2–3 thousand years owing to the spread of bacterial and viral infections. For some genetic variants and polygenic traits, an alteration of the direction of natural selection in Europe has been documented, e. g., for those associated with an immune response and cognitive abilities. Examination of the correlation between fertility and educational attainment yields conflicting results. In modern populations, to a greater extent than previously, there is selection for variants of genes responsible for social adaptation and behavioral phenotypes. In particular, several articles have shown a positive correlation of fertility with polygenic risk scores of attention deficit/hyperactivity disorder.

Purpose. To identify the attitude and stereotypical perception of the population about the use of in vitro fertilization (IVF) in the Republic of Belarus. Material and methods. A sociological survey of a representative republican sample, which consisted of 1805 respondents (851 (47%) men, 954 (53%) women) aged 18 to 65 years, was performed. Results. In general, there is a positive attitude on the part of society towards reproductive technologies (21.6% of respondents claimed absolutely positive attitude and 30.2% had rather positive attitude to IVF; a neutral attitude was revealed in 37.1% of respondents). Some of the population retain stereotypes associated with varying degrees of influence of reproductive technologies on the psychophysical health of children (about 34%). Conclusion. A system of measures is needed to improve the preparation of married couples with an established diagnosis of infertility and the ineffectiveness of other treatment methods for artificial conception. This approach will minimize the number of failed IVF cycles and reduce the risk of complications for the mother and child. The effective use of assisted reproductive technologies (ART) with positive outcomes in overcoming infertility will contribute to the formation of a positive attitude towards reproductive technologies on the part of society.
