  Heterochromatin polymorphism is considered a variant of a normal karyotype but is more frequent in infertile men. The aim of this study was to evaluate the correlation between heterochromatic variants and male infertility and to discuss the possible mechanisms of how heterochromatic polymorphism might affect spermatogenesis. Methods: Cytogenetic analysis was undertaken in a group of 392 infertile men from the Andrology Outpatient Clinic of the Human Reproduction Service of the ABC School of Medicine. Additionally, C-banding was performed in men with heterochromatin polymorphism, and NOR-banding in men with satellites variations. Results: 47 patients of the sample showed chromosomal variants (12% of the sample). Considering these men, 8 presented idiopathic infertility, where 19 presented severe oligozoospermia, 18 had non-obstructive .. View More»
