Abstract:
Objective:To explore the relationship between the polymorphisms of SIRT1 and follicle-stimulating hormone receptor (FSHR) gene and ovarian function in women who underwent assisted reproductive technology (ART) and the differences between Mongolian and Han nationalities, so as to provide basis for the individualized treatment of ART assisted pregnancy. Methods:A retrospective cohort study was performed. The clinical data of 204 ART patients who visited the Reproductive Center of the Affiliated Hospital of Inner Mongolia Medical University from September 2019 to September 2021 were collected. There were 53 cases of Mongolian nationality and 151 cases of Han nationality. MassARRAY SNP genotyping technology was used to detect three sites, which were rs2236319 of SIRT1 and rs6165 and rs6166 of FSHR. SIRT1 was divided into three groups: AA group (wild type), AG group (heterozygous type) and GG group (mutant type); FSHR rs6165 was divided into TT group (wild type), AT group (heterozygous type), AA group (mutant type); FSHR rs6166 was divided into NN group (wild type), NS group (heterozygous type) and SS group (mutant type). The differences of genotype frequency and clinical and laboratory data were compared. Results:1) The allele frequencies and genotype frequencies of SIRT1 rs2236319, FSHR rs6165, and rs6166 loci were not statistically different in composition between Mongolian and Han ART female patient groups. There were no significant differences between Mongolian and Han ART women in terms of general clinical data and basal sex hormones and ovarian reserve function (all P>0.05). 2) There was a statistically significant difference in the number of eggs captured at the rs2236319 locus of the SIRT1 gene among the mutant GG group [18.5 (13.0, 32.8)], the AA group [13.0 (7.0, 20.0)] and the AG group [10.0 (5.0, 21.0), P=0.019]. 3) There was a statistically significant difference in the basal FSH levels at the rs6165 locus of the FSHR gene among the AA group [(7.45±2.73) U/L], the TT group [(5.97±2.23) U/L] and the TA group [(6.70±2.04) U/L, P=0.005]. The proportion of ovarian hyporesponsiveness among the AA group [29.6% (8/27)], the TT group [8.5% (8/94)] and the TA group [13.3% (11/83)] was statistically significant ( P=0.017). 4) The difference in basal FSH levels at the rs6166 locus of the FSHR gene among the SS group [(7.48±2.78) U/L], the NN group [(6.08±2.28) U/L] and the NS group [(6.61±1.99) U/L] was statistically significant ( P=0.016). The proportion of ovarian hyporesponsiveness among the SS group [37.0% (10/26)], the NN group [8.5% (8/99)] and the NS group [10.8% (9/79)] was statistically significant ( P=0.001). Conclusion:There were no significant differences between Mongolian and Han ART women in terms of general clinical data, basal sex hormones and ovarian reserve function. The gene polymorphism at rs2236319 of SIRT1 gene is associated with ovarian hyperresponsiveness. FSHR rs6165 and rs6166 gene polymorphisms are associated with ovarian hyporesponsiveness. There was no significant correlation between the three polymorphisms and the clinical pregnancy rate of ART.
