Abstract

Background: Poor ovarian response (POR) during in vitro fertilization (IVF) remains a major challenge, adversely affecting both the emotional wellbeing of patients and clinical outcomes. Genetic polymorphisms, particularly in the anti Müllerian hormone (AMH) gene, such as rs10407022, have been suggested to contribute to POR. This study aimed to investigate the association between the rs10407022 polymorphism and POR, as defined by the POSEIDON criteria, among Iranian women.
Methods: In this analytical case-control study, 232 women under 45 years with poor ovarian response according to the POSEIDON criteria and 56 women with normal ovarian response (controls) were included. Demographic, hormonal, and ovarian reserve parameters, including age, BMI, FSH, AMH, and AFC, were recorded. Genotyping of the AMH rs10407022 (G/T) polymorphism was performed using ARMS-PCR, and associations were assessed using logistic regression adjusted for age and BMI.
Results: Cases exhibited significantly lower AMH levels (0.9 ± 0.4 ng/mL vs. 2.6 ± 0.8 ng/mL, p < 0.001), lower AFC, and higher day 3 FSH compared to controls. Notably, all participants in both groups had only the GT genotype for rs10407022, with no GG or TT genotypes observed. This finding indicates that the rs10407022 locus was monomorphic in this Iranian cohort, precluding any significant association with POR.
Conclusion: The AMH rs10407022 polymorphism was monomorphic in this Iranian population, exhibiting only the GT genotype. While significant differences in hormonal markers were observed between POR and normal responders, this single nucleotide polymorphism (SNP) did not account for the variability in ovarian response. Further large-scale, multiethnic studies are warranted to elucidate the genetic underpinnings of POR.
