Fertil Steril. 1977 Feb;28(2):209-10.
Chromosome studies were conducted on 117 men with primary infertility (54 with oligospermia and 63 with azoospermia) and 25 fertile volunteers who acted as controls. No chromosomal abnormalities were observed except for nine cases of Klinefelter's syndrome. From this study, it is apparent that chromosomal abnormalities other than Klinefelter's syndrome are not etiologic factors in the infertility of oligo- or azoospermic men.
对117名原发性不育男性（54名少精子症患者和63名无精子症患者）以及25名作为对照的有生育能力的志愿者进行了染色体研究。除9例克兰费尔特综合征外，未观察到染色体异常。从这项研究可以明显看出，除克兰费尔特综合征外的染色体异常不是少精子症或无精子症男性不育的病因。
