title: [Y-chromosome microdeletions as a prognostic marker of male infertility].
abstract: The results of molecular-genetic study of Y-chromosome microdeletions in men with spermatogenesis failure and in patients with cryptorchism are presented. The molecular-genetic studies of regions AZFa, AZFb, AZFc in STS loci - sY84, sY86, sY127, sY134, sY254, sY255 and SRY gene have been performed. Y-chromosome microdeletions were detected in 13,3% infertile men with spermogram failure. The frequency of genetic (cyto- and molecular) abnormalities among boys with isolated cryptorchism was 4%. The results show the necessity of additional study ofgenetic factors ofcryptorchism development.
