[Chromosomal investigation in infertile cases of azoospermia].
Chromosomal examination in 85 patients with azoospermia revealed 62 patients (73%) with the karyotype 46, XY and 23 patients (27%) with other abnormal karyotypes. In this population, there were 17 patients with 47, XXY. Other anomalies were: 46, XYp+, 46, XXp+, 46, XYp-, 45, X, t (Ynf; 21), 45, XY, t (13q 15q), and 46, XY, r (18). Serum LH and FSH levels were high and testosterone level was low in the patients with 47, XXY compared with the other 6 patients (p less than 0.01). Also the mean value of testicular volume was low in the patients with 47, XXY (p less than 0.05).
