Methods: To analyze the relevant genes of the Y-chromosome and the karyotype of peripheral blood chromosome in 149 azoospermic/sever oligo-spermic infertile men and 100 normal controls by multipolymerase chain reaction (PCR). Results: Microdeletions in different gene segments of the Y-chromosome were present in 11 cases of the infertile group (7.38 %). No microdeletion in the corresponding areas was found in the controls. The incidence of abnormal karyotype in the infertile group was 14.09 % and in the controls, 2 %. In the 11 infertiles with microdeletion in different gene segments, only one had abnormal karyotype, indicating no relativity between the two. Conclusion: Microdeletion of Y-chromosome may be an important cause of male infertility.展开更多
