摘要 目的初步探讨男性受到低剂量电离辐射后的生殖安全性。方法将21份新鲜精液标本每份精液分成3组(对照组、1mGy组、50mGy组),1mGy组、50mGy组的精液样本分别接受1mGy(相当于普通X线片的剂量)和50mGy(相当于CT检查的剂量)的X线照射。照射后分别对3组精液样本的精子活力、精子存活率、精子运动特征及精子DNA完整性等指标进行检测和比较。结果各组间精子活力、精子存活率、精子运动特征参数、精子DNA完整性经配对t检验比较不同组别指标间的差异没有统计学意义(均P>0.05)。结论常规放射学检查对男性成熟的精子是相对安全的,但对男性生精功能、精子的受精功能以及子代的安全性还需进一步深入研究。
