Popis: The objective of the study was to assess the frequency of Y-chromosome microdeletions and cytogenetic rearrangements in couples presenting with a male factor-infertility and to evaluate under which indications these genetic analysis should be recommended. Y-chromosome microdeletions were detected in 4.6% of patients with altered spermatogenesis. The incidence of deletion Yq was 13.3% in males with non-obstructive severe oligospermia and azoospermia. The incidences of chromosome anomalies and of chromosome variants were 2.1% and 0.6% respectively. Our study confirms that a subgroup of men with azoospermia and severe oligospermia are at high risk for Y-chromosome microdeletions. It is therefore recommended to screen them for microdeletions of the Y-chromosome before applying ICSI treatment for infertility. Cytogenetic evaluation is also justifiable as part of the investigation for these patients.
