Spinal Cord:脊髓损伤男性精液中精子DNA断裂的患病率和病因研究

2020-02-10 AlexYang MedSci原创

最近,有研究人员在一个回顾描述性研究中确定了脊髓损伤(SCI)男性患者中精子DNA片段化(SDF)的患病率和可能的病因。研究人员在不同程度脊髓损伤的27名男性患者中通过震动刺激的方式搜集了他们的精液,并评估了经典的精液参数、SDF、白细胞精子症和促氧化能力,并与10名正常健康的捐赠者进行了比较。研究发现,与正常健康的捐赠者精液相比,SCI男性患者表现出了更低的精液质量,包括了渐进运动能力(p=0.

最近,有研究人员在一个回顾描述性研究中确定了脊髓损伤(SCI)男性患者中精子DNA片段化(SDF)的患病率和可能的病因。

研究人员在不同程度脊髓损伤的27名男性患者中通过震动刺激的方式搜集了他们的精液,并评估了经典的精液参数、SDF、白细胞精子症和促氧化能力,并与10名正常健康的捐赠者进行了比较。研究发现,与正常健康的捐赠者精液相比,SCI男性患者表现出了更低的精液质量,包括了渐进运动能力(p=0.0002)、SDF(p<0.00005)、促氧化能力(p=0.0191)和白细胞精子症(p<0.00005)。尽管精液质量和病变发生的时间之间没有明显的相关性,禁欲的时间与SDF表现出了正相关关系(r=0.486; p=0.041)。当SCI患者的精液参数根据颈和胸椎病变分类时,研究发现,颈椎损伤患者的精子浓度要显著更高(p=0.0257)。另外,完全病变的男性(AIS A)射精的渐进运动能力要比不完全损伤(AIS B-D)更低(p=0.0040)。

最后,研究人员指出,SCI男性患者的精液SDF显著提高,很可能是与并发的高水平白细胞缺乏症和促氧化能力相关。因此,研究人员认为这些迹象是由于附睾尾精子的积累和退化引起的。
