背景 过去几十年来，中国的人类精液质量有所下降。前期研究发现，按照1999年世界卫生组织标准，重庆市61.1%的健康男性精液参数值异常。 目的 本横断面研究探讨重庆市社会心理行为因素与精液质量的关系。 方法 研究对象为1346名符合条件的健康男性，对15个社会心理行为因素进行检查和研究。 结果男性的精液量较多（β系数1.18，p=0.034），而经常穿人造纤维内衣的男性形态正常精子的比例较低（β系数0.82，p=0.001）。在心理压力方面，压力较小的男性精子总数和形态正常精子的百分比增加（β系数分别为1.19和1.25，p分别为0.02和0.04）。研究中检查的其他12个因素表明重庆市精液质量与精液质量没有显着相关性。结论精液质量可能受到社会心理行为因素（职业阶层、心理压力和穿着化纤内衣）的影响。直接涉及心理健康和健康生活方式的健康计划以及针对男性社会因素的政策的实施可能会在改善中国男性生殖健康方面发挥作用。
Background Human semen quality in China has decreased in the last few decades. A previous study found that 61.1% of healthy males in Chongqing City in Southwest China had abnormal semen parameters values according to 1999 World Health Organization criteria.Objective This cross-sectional study explored the associations between socio-psycho-behavioural factors and semen quality in Chongqing City.Methods The study participants comprised 1346 eligible healthy men who were examined and researched in respect to 15 socio-psycho-behavioural factors.Results Men from a higher occupational class had better semen volume (beta coefficient 1.18, p=0.034), while men who often wore underwear made from man-made fibres had a lower percentage of morphologically normal sperm (beta coefficient 0.82, p=0.001). As regards psychological stress, men with less stress had an increased total sperm count and percentage of morphologically normal sperm (beta coefficient 1.19 and 1.25 respectively, p=0.02 and 0.04 respectively). The other 12 factors examined in the study demonstrated no significant association with semen quality in Chongqing.Conclusions Semen quality can be impacted by socio-psycho-behavioural factors (occupational class, psychological stress and wearing man-made fibre underwear). A health programme that deals directly with psychological health and healthy lifestyle, and the implementation of policies that address social factors for men may play a part in the improvement of male reproductive health in China.
