对河南“4.26”60Co源辐射事故中4名成年男性患者分别于照后1周、3个月、6个月、1年、2年、3年和5年进行询问、精液常规检查,以及应用放射免疫分析法测定睾酮(T)、卵泡刺激素(FSH)和黄体生成素(LH)。结果显示,4名受照者照后性欲无明显改变;T均处于正常水平,FSH、LH照后1年偏高;4名受照者照后3个月精子数明显减少或缺乏,活动率明显下降,活动力不良,可见畸形精子。照后6个月至1年精子为0。照后2年精子开始恢复。提示电离辐射对男性性腺的损伤程度与照射剂量相关。
Four adult male patients in Henan “4.26 ” 60Co radiation accident were interrogated one week, three months, six months, one year, two years, three years and five years respectively after the irradiation, routine examination of semen, And testosterone (T), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were measured by radioimmunoassay. The results showed that there was no significant change in libido among the four recipients; T were all in the normal level, FSH and LH were high after one year; the number of sperm in four recipients was significantly decreased or lacked after three months, activity rate Significant decline, poor mobility, showing abnormal sperm. 6 months to 1 year after sperm to 0. 2 years after sperm began to recover. Prompted ionizing radiation damage to the male gonads and dose related.
