To estimate the prevalence of the nonclassical form of congenital adrenal cortical dysfunction genetically confirmed, a molecular genetic test was performed in 86 married ethnic Armenian patients with infertility. A control group included 30 fertile women. Endocrinopathies were ascertained to be the leading cause of reproductive dysfunction (72.1%). Impaired adrenal steroidogenesis that was both concurrent with other endocrine forms of infertility and presented with isolated adrenal cortical damage was found in 55 (88.7%) patients. The heterozygous carriage of congenital adrenal cortical dysfunction, namely the detection of mutations of two (Pro31Leu and Val282Leu) polymorphisms of the СУР21А2 gene, was 5.2%. There was evidence that molecular genetic testing should be incorporated into an examination algorithm for women with hyperandrogenism identified by clinical and laboratory studies.
