The association of ESR1 PvuII polymorphism (rs2334693) with impaired ovarian reserve was studied by genotyping this polymorphism using PCR-RFLP in patients and two control groups from Ukraine. Statistically significant differences in the prevalence of p-allele frequency (-397T) was seen in the group of patients with impaired ovarian reserve (0.597) compared to control groups I under 35years (0.480) and II over 35years (0.453), both p<0.05. The data suggest that PvuII polymorphism of ESR1 is associated with diminished ovarian reserve.
