To identify the factors associated with male semen quality from many socio-psycho-behavioral factors.
Medline/PubMed, EMBASE, and CNKI were searched to identify relevant publications for systematic review and meta-analysis.
PATIENT(S): None.
INTERVENTION(S): None.
MAIN OUTCOME MEASURE(S): Thirteen socio-psycho-behavioral factors in 57 cross-sectional studies with 29,914 participants from 26 countries/regions were involved in this review. Six factors (age, body mass index [BMI], psychological stress, smoking, alcohol, and coffee consumption) were included in meta-analyses.
RESULT(S): Smoking can deteriorate all of the sperm parameters of both fertile and infertile men, but it is not risk factor for semen volume in Switzerland and Iran and for sperm density in the United States, Denmark, and Brazil; higher age and alcohol consumption are risk factors for lower semen volume; and psychological stress can lower sperm density and sperm progressive motility and increase abnormal sperm.
CONCLUSION(S): This review further suggested that higher age, smoking, alcohol consumption, and psychological stress were risk factors for semen quality. These results indicated that health programs focusing on lifestyle and psychological health would be helpful for male reproductive health. Well-designed studies are needed to further identify the role of more socio-psycho-behavioral factors in male semen quality.
从众多社会心理行为因素中确定与男性精液质量相关的因素。

本综述共纳入 26 个国家/地区的 57 项横断面研究，涉及 29914 名参与者，涉及 13 个社会心理行为因素。有 6 个因素（年龄、体重指数[BMI]、心理压力、吸烟、饮酒和咖啡摄入）进行了荟萃分析。
吸烟可降低有生育能力和无生育能力男性的所有精子参数，但在瑞士和伊朗，吸烟不是精液量的危险因素，在美国、丹麦和巴西，吸烟也不是精子密度的危险因素；较高的年龄和饮酒是精液量减少的危险因素；心理压力可降低精子密度和精子前向运动能力，并增加异常精子。
本综述进一步表明，年龄较大、吸烟、饮酒和心理压力是精液质量的危险因素。这些结果表明，关注生活方式和心理健康的健康计划将有助于男性生殖健康。需要进行精心设计的研究，以进一步确定更多社会心理行为因素在男性精液质量中的作用。
