结论异常孕产史不但与染色体畸变有关，与染色体多态性也有关联。
Conclusions Abnormal pregnancy-labor history is not only associated with chromosome aberration, but also with chromosome polymorphism.
染色体多态性17例，占异常核型的9.83%，主要包括Y染色体多态性、次缢痕和随体的变异。
There were 17 cases of chromosome polymorphism, accounting for 9.83% of all abnormal karyotypes. It contains Y chromosome, secondary constriction, and variation of satellites.
结果1009例男性不育患者中染色体异常者有61例，异常率为6.05%，染色体多态性者43(4.26%)例。
Results: There were 61 patients with chromosome abnormalities among 1009 infertility male, the abnormal rate was 6.05%, and 43 (4.26%) patients with chromosome polymorphism.
