本文作者采用人精子与去透明带金黄地鼠卵离体受精，继续培养异合卵至第一次卵裂获得人精子染色体标本的新技术，对两例在６０Ｃｏγ射线辐射事故中全身受照男性照后６（７）年１３８个精于和６例正常男性２４０个精子染色体核型进行分析，直接观察健康人全身受６０Ｃｏγ射线照射后，精子发生的远期效应，研究结果表明：①电离辐射对人精子的远期遗传学效应的靶细胞是生殖干细胞；②受损生殖干细胞来源的精子，其染色体畸变率显著增高，结构畸变类型主要是末端缺失，其次为易位、双着丝粒体、四射体等；③这些异常精子的受精能力没有受到可检出的影响：④Ｙ－精子与Ｘ－精子的比例较对照组明显增高。
In this study, we used in vitro fertilization of human sperm and golden hamster de-zona pellucida to further develop a new technique to obtain the human sperm chromosome from the ectopic egg to the first cleavage. According to the analysis of karyotypes of 138 sperm cells in 6 (7) years and 240 normal sperm in 6 (7) years, we directly observed the long-term effects of spermatogenesis on 60Co γ-rays in healthy volunteers. The results showed that: ① ionizing radiation The target cells of long-term genetic effect on human sperm are germline stem cells; ② The sperm chromosomes of damaged spermatogenic stem cells have a significantly higher chromosome aberration rate, the main types of structural aberrations are terminal deletion, followed by translocation, , Quadrupole, etc .; ③ The fertility of these abnormal sperm was not detectable effect: ④ Y-sperm and X-sperm ratio was significantly higher than the control group.
