摘要
目的:对无精症和少精子症患者进行外周血染色体及Y染色体微缺失检测,探讨生精功能障碍的遗传学机制,为临床治疗和遗传咨询提供参考。方法:运用细胞遗传学核型分析技术和多重PCR技术对133例生精功能障碍患者进行染色体核型分析和Y染色体AZF因子扩增,并以40例已生育男性作为对照组。结果:实验组中61例无精子症患者中,细胞遗传学核型数量异常13例,异常发生率21.31%,同时发现AZF微缺失6例,异常发生率9.84%;72例少精患者细胞遗传学核型异常11例,异常发生率15.28%,同时发现AZF微缺失7例,异常发生率9.72%。40例对照组Y染色体核型和AZF位点无缺失。结论:染色体异常和AZF的缺失是引起男性无精子和少精子并造成男性不育的重要原因之一,对男性不育人群进行细胞遗传学核型分析和AZF检测十分必要。
Objective:To carry out chromosome and Y chromosome microdeletion test in peripheral blood of patients with azoospermia and oligozoospermia,explore genetic mechanism of spermatogenic arrest,provide a reference for clinical treatment and genetic consultation. Methods:Cytogenetic karyotype analysis technique and multiplex polymerase chain reaction(PCR) technique were used for chromosomal karyotype analysis and azoospermia factor(AZF) amplification of Y chromosome among 133 patients with spermatogenic arrest,40 men with children were selected as control group. Results:Among 61 patients with azoospermia in experimental group,13 patients were found with abnormal chromosomal number,the incidence was 21.31%;6 patients were found with AZF microdeletion,the incidence was 9.84%.Among 72 patients with oligozoospermia in experimental group,11 patients were found with abnormal chromosomal number,the incidence was 15.28%,7 patients were found with AZF microdeletion,the incidence was 9.72%.Among 40 patients in control group,no abnormal chromosomal number and AZF microdeletion occurred. Conclusion:Chromosomal abnormality and Y chromosome microdeletion are important causes of male azoospermia,oligozoospermia and male infertility,it is necessary to carry out cytogenetic karyotype analysis and AZF test among male infertile population.
