摘要
目的通过对孕前检查的男性和捐精人群之间的Y染色体臂间倒位[inv(Y)]携带率的比较,探讨Y染色体臂间倒位与不育的关系,进一步说明Y染色体臂间倒位产生的临床效应。方法在2014年1月至2020年12月间来广东省生殖医院进行染色体检测的男性和捐精人群中,统计发生inv(Y)的例数,并统计该类携带者的精液质量和Y染色体微缺失检测(AZF)检查的结果。结果10530例孕前健康检查男性中共有34例inv(Y)的携带者,4709例来捐精的人群中共有18例inv(Y)的携带者,inv(Y)的携带率在孕前检查的男性和捐精者之间差异无统计学意义。结论inv(Y)携带者在男性中有一定的携带率,一般不会引起不育或其他病理性临床表现。
Objective To investigate the relationship between pericentric inversion of the human Y chro-mosome[inv(Y)]and infertility by comparing the positive rate of pericentricinv(Y)between males underwent pre-pregnancy examination and sperm donors,and to further illustrate the clinical effect of pericentricinv(Y).Methods Between January 2014 and December 2020,the males and sperm donors admitted to Guangdong provincial Fertility hospital for chromosome examination were included as the subjects in the study,and the number of pericentricinv(Y)was counted.The semen quality of such carriers and the results of azoospermia factor(AZF)test were statistically analyzed.Results There were 34 carriers of pericentricinv(Y)among 10530 males underwent pre-pregnancy examination,and 18 carriers of pericentricinv(Y)among 4709 sperm donors.There was no statistically significant difference in the positive rate of pericentricinv(Y)between males underwent pre-pregnancy examination and sperm donors.Conclusion There is a certain positive rate of pericentricinv(Y)among males.It generally does not cause infertility or other pathological manifestations in the clinical settings.
