Abstract

Background. Ovarian hyperstimulation syndrome is a fatal complication of unknown etiology. In connection with the increase in the frequency of this complication, it is necessary to identify prognostically significant markers to discover the risk of its development. Aim. To analyze the frequency of ovarian hyperstimulation syndrome and search for the association of genes for differential growth factor 9, luteinizing hormone/horiogonadotropin receptor, and follicle-stimulating hormone receptor with different responses to ovulation stimulation. Material and methods. A retrospective single-center cohort study of the frequency and clinical parameters of early ovarian hyperstimulation syndrome was carried out in 147 patients, the average age was 36.5 [3338] years, who underwent an in vitro fertilization program in the period 20062021 in the Department of Assisted Reproductive Technologies of the Republican Medical Genetic Center in Ufa. The study of polymorphic loci of the genes for differential growth factor 9, luteinizing hormone/choriogonadotropin receptor, and follicle-stimulating hormone receptor was performed using TaqMan technology and real-time polymerase chain reaction. Deoxyribonucleic acid was isolated from peripheral blood samples. Statistical analysis was performed using the KruskalWallis criteria, median test, Pearson's 2 test, using the Statistica 12 software package. Results. 7577 procedures of assisted reproductive technologies were performed. 147 (2.3%) cases of ovarian hyperstimulation syndrome were registered, 53 (0.8%) cases of moderate and severe degree, 84 (1.3%) cases of mild degree. The *CT genotype of the rs254286 polymorphic locus of the differential growth factor 9 gene was associated with a poor ovarian response 15 (0.75); (2=4.00; p=0.02; odds ratio 3.4; 95% confidence interval 1.1310.27). The distribution of allele and genotype frequencies of the other studied genes did not differ statistically significantly in all the studied groups. Conclusion. The frequency of ovarian hyperstimulation syndrome in the Republic of Bashkortostan was 2.3%; the *CT genotype of the rs254286 polymorphic locus of the differential growth factor 9 gene, as well as the level of anti-Mllerian hormone, can serve as markers of a poor response and ovarian hyperstimulation to ovulation stimulation.
