摘　　要：目的:了解三峡库区重庆段男性精液质量现状及其地域分布特点,评估三峡库区重庆段男性生殖健康现状。方法:选择重庆市境内长江流经的6个区县(南岸区、沙坪坝区、忠县、万州区、云阳县、巫山)的1 976例男性,按照WHO第四版精液分析标准采取精液,现场进行精液质量分析,利用精液质量来评估男性生殖健康现状。结果:重庆市6区县的男性的精液参数(精液量、精子密度、精子总数、精子活动率、精子形态正常率)均值都在正常范围;精子活力(a+b)%正常仅见于沙坪坝区、云阳县和忠县男性,其他3个区的男性精子活力(a+b)%异常。6区县男性精液参数比较,差异具有显著性(P<0.05);各区县健康男性精液参数[酸碱度、液化时间、精液体积、精子密度、前向运动精子(a%)、活力(a+b)%、活动率]均正常的不足50%,正常率最高的是云阳县,为47%;而万州区,仅仅16%的男性上述精液参数完全正常。利用G IS软件将精液参数作空间分布图,6区县男性精液质量分布呈现地域性差异,云阳县男性精液质量最好,万州区和巫山县最差。结论:三峡库区重庆段男性精液质量水平较低,并随长江流向呈现地域性差异。Objective： To investigate the quality and spatial distribution features of semen and to evaluate the reproductive health of the males in the Chongqing section of the Three-Gorge Reservoir area. Methods ： We collected semen samples by masturbation after 2 -7 days of abstinence from the men in Nan＇an, Shapingba, Zhongxian, Wanzhou, Yunyang and Wushan of Chongqing, which are geographically and demographically representative of the Three-Gorge Reservoir area. We analyzed the semen quality of all the samples and evaluated the reproductive health of the men. Results ： The mean value of the five semen parameters of the male subjects from the six districts was within the normal range, including semen volume, sperm concentration, total sperm count, rapid progressive motile sperm, and total motile sperm. Those from Shapingba, Yunyang and Zhongxian exhibited abnormal sperm motility. According to the WHO criteria, normal value of all the semen parameters was found in less than 50% of the semen samples from the six districts, in 47% of those from Yunyang, and only 16% of those from Wanzhou. Spatial distribution maps of the semen parameters revealed significant spatial differences in seminal quality among the six districts, the highest in Yunyang, and the lowest in Wanzhou and Wushan that are located in the middle and lower reaches of the Three-Gorge Reservoir area. Conclusion ： The mean value of semen parameters was low in a large proportion of men in the Chongqing section of the Three-Gorge Reservoir area, with spatial differences along the Changjiang river.
