目的初步探讨9号染色体倒位与不孕不育的关系。方法以562例不孕不育患者作为不孕不育组、4789例非不孕不育原因进行遗传咨询的患者作为对照组,进行外周血淋巴细胞培养染色体核型分析,采用G显带法。结果与对照组比较,不孕不育组inv(9)检出率比对照组高(4.45%vs 2.32%,P=0.002)。不孕不育组男性的inv(9)检出率高于对照组男性、对照组女性,有极显著统计学意义。而且,不孕不育组男性的inv(9)检出率比该组女性高104%。结论不孕不育人群的inv(9)携带者率比其他人群高,而且不育男性的inv(9)携带者比率比不孕女性高。
Objective To investigate the relationship between chromosome 9 inversions and infertility. Methods 562 cases of infertility patients as infertility group, 4789 cases of non-infertility causes genetic counseling patients as a control group, the peripheral blood lymphocytes cultured chromosome karyotype analysis using G-banding method. Results Compared with the control group, the detection rate of inv (9) in infertility group was higher than that in control group (4.45% vs 2.32%, P = 0.002). Infertility group male inv (9) detection rate was higher than the control group of men, the control group of women, a very significant statistically significant. In addition, the detection rate of inv (9) in infertile men was 104% higher than that of women in this group. Conclusions Infertility is associated with a higher rate of inv (9) carriers than any other population, and infertile men have a higher rate of inv (9) carriers than infertile women.
