摘要
男性不育原因颇多,其中一部分为染色体异常所致[1].我们对50例无精症患者进行外周血淋巴细胞染色体分析,结果发现16例性染色体数目或结构异常,占32.0%。其中del(Y)(qll)2例、大Y1例、47,XXY纯合型6例、47,XXY/46,XY各种嵌合型4例、46,XY/45,X2例以及46,XX1例。本文并结合文献讨论了无精与性染色体之间关系,对1例罕见的性反转综合症患者进行初步的分析。
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.
