Abstract: Male infertility is one of the most common causes in abnormal fertility。Some of them have chromosomal unusualness.Cytogenetic investigations were carried out on 50 males with azoospermia。Chromosomal prepartions made from peripheral blood lymphocytes were analysed with conventional GTG and CBG banding techniques.We found 16 patients showed numerical structural abnormalities of sex chromosome (32.0%):2 subjects With del(Y)(q11),1 with a large Y(Y+),6 with47,XXY,4 with 47,XXY/46,XY,2 with 46,XY/45,X and 1 with 46,XX. The relationship between sex chromosome and azoospermia is discussed.The 46,XX male iS a very rarely case known as sex reversed syndrome.For this case,further studies were needed to ascertain the presence of Yp specific materials.
