Total chromosome alterations were revealed in 31% of infertile men. Major chromosomal abnormalities had a 10-fold increase in infertile males compared to the control group. In azoospermics, the most prevalent were sex chromosomal abnormalities (47, XXY) (22.7%); mosaicism that is 47, XXY/48, XXYY was seen in one patient. One patient showed 46, XX karyotype and variations in Y chromosome was identified. Whereas in oligozoospemric men polymorphic variations were observed in chromosome 1, 9, Y and presence of satellite in chromosome 15 and 21 and robertsonian translocation (13/14) were also identified. The most frequently observed polymorphisms involved chromosome 9. In conclusion, chromosomal abnormalities found with a hi...
