               [摘   要] 目的:分析南京医科大学附属第一医院精子库10余年来捐精志愿者者染色体遗传学特征,探讨精子库染色体核型
                分析在避免供精治疗后不良妊娠结局中的作用。方法:回顾性统计2012年1月—2023年12月于南京医科大学附属第一医院
                人类精子库进行供精筛选的捐精者共计3 591例的染色体检查结果,分类染色体核型异常分布与类型。结果:3 591例捐精志
                愿者中,染色体核型出现异常者共62例(1.73%),其中最常见的为臂间倒位(30/62),其次为次缢痕区加长(13/62),再次为染色
                体短臂加长(7/62)、染色体易位(6/62)。此外,还有随体加长3例,双随体1例,着丝粒增大1例,标记染色体1例。结论:鉴于
                核型异常对妊娠结局与子代健康已知或潜在的不良影响,精子库必须对捐精志愿者进行严格的细胞遗传学筛查,以规避后续
                供精治疗的失败风险,达到助孕优生的社会作用。

               [Abstract] Objective:To analyze the genetic characteristics of chromosomes of sperm donor volunteers in human sperm bank of the
                First Affiliated Hospital of Nanjing Medical University,for more than ten years,and to explore the role of sperm bank chromosomal
                karyotypes analysis and screening in avoiding adverse pregnancy outcomes after sperm donor treatment. Methods:The chromosomal
                karyotypes examination results of 3 591 sperm donors,who underwent sperm screening at the Human Sperm Bank of the First Affiliated
                Hospital of Nanjing Medical University from January 2012 to December 2023,were retrospectively analyzed to classify the distribution
                and types of chromosomal karyotypes abnormalities. Results:Among the 3 591 sperm donors,there were 62 cases of karyotype
                abnormalities,accounting for 1.73% of all volunteers,of which the most common were pericentric inversions(30/62),followed by
                secondary constriction region enlargement(13/62),and then short⁃arm enlargement(7/62)and translocation(6/62). In addition to this,
                there were 3 cases of satellite enlargement,1 case of double enlargement,1 case of enlarged centromere,and 1 case of marker
                chromosome. Conclusion:In view of the known or potential adverse effects of karyotype abnormalities on pregnancy outcomes and
                offspring health,sperm banks are required to conduct rigorous cytogenetic screening of sperm donor volunteers to circumvent the risk
                of failure of subsequent sperm donor treatments and to fulfil the societal role of assisted conception and eugenics.
