摘　　要：目的探讨远洋捕捞环境对船员精液质量的影响。方法研究对象为2000年3月-2006年9月间从事远洋捕捞作业的船员志愿者30例。对其去远洋前后的精液进行自身对照研究,分析精液的参数及精浆中重金属元素的含量。结果与去远洋前比较,远洋回来后靠岸时船员的精液常规参数中精液量、精子密度、正常形态的精子比例及精子活动率均显著下降(P<0.05或P<0.01);精子活力在远洋回来后显著降低(P<0.05);精浆中的重金属元素汞的含量在远洋回来后显著增高(P<0.05),精浆中锌、铜、铅及镉元素的含量均有不同程度的升高,但无统计学意义(P>0.05)。远洋回来3月后精液常规参数、精子活动参数及精浆中的重金属元素含量回归,与去远洋前水平无明显差异。结论与去远洋前相比,远洋回来后船员的精液质量下降;精液质量的下降可在3个月内恢复。Objective To investigate the effect of long-term navigation on semen quality. Methods Thirty seamen who engaged in long-term navigation as volunteers were enrolled in this study. Their semen was collected respectively before and after cruise; and then the quality of semen was comparatively analyzed. Results After cruise, value of several parameters was lower than that before cruise（P〈0.05 or P〈0.01）, such as semen volume, sperm density, the proportion of normal sperm morphology and sperm motility, whereas for other parameters including sperm liquefacion time and PH, no significant change was found（P〉0.05）. The percentage of sperm in grade（a） and grade（a＋b） were significantly lower after cruise than that before cruise（P〈0.05）. The content of mercury element in semen was significantly higher after cruise （P〈0.05） while other heavy metals such as Zinc, copper, lead and cadmium elements were no obvious change（P〉0.05）. Three months later,level of semen parameters,sperm motility parameters, heavy metals in semen recovered to the original level before cruse. Conclusion In comparison with that before cruising, the quality of semen was depressed after cruising, but this change will be recovered in three month after the cruise was over.
