In this study, chromosome analyses were performed on 70 infertile Azoospermic and Oligospermic (<20 million/ml) men, and also cultures of peripheral blood lymphocytes by high resolution banding method were analysed as well. It is revealed 8 (11.43 percent) men with chromosomal abnormality. There were 31.4 percent patients with azoospermia and 68.6 percent with oligospermia from several thousands to 20×10^6 million/ml and their duration of infertility was at least 2 years. All patients with numerical chromosome anomalies had azoospermia and the most frequent anomaly was 47, XXY chromosomal constitution (klinfelter's syndrome), found in 8.57 percent of patients. We found that chromosomal anomalies found in this study were sex chromosome anomalies and an increased rate of numerical chromosomal abnormalities was among men with azoospermia. As a conclusion, we suggest that all men with azoospermia be considered for cytogenetical evaluation.
