Introduction: The FMR1 gene plays an important role in brain development and in the regulation of ovarian function. The FMR1 gene contains CGG repeat variation and the expansion of the repeats is associated with various phenotypes e.g. fragile X syndrome, premature ovarian failure, etc. Repeats ranging < 55 CGG are considered normal, however recent studies suggest that high-normal (35-54 CGG) and low-normal ([removed] 0.05). In addition, the analysis of low-normal allele and genotype frequencies did not present a difference between primary, secondary infertility and the control group (p > 0.05). Conclusions: In our study, the FMR1 gene high-normal alleles were associated with secondary infertility. However, to address the controversies related to the role of FMR1 genes in the development of diminished ovarian reserve, further studies on the subject are required.
