Studies suggest that appropriate nutritional modifications can improve the natural conception rate of infertile couples.
The purpose of this study was to review the human trials that investigated the relation between nutrition and male infertility.
A comprehensive systematic review of published human studies was carried out by searching scientific databases. Article selection was carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The American Dietetic Association Research Design and Implementation Checklist was also used for quality assessment.
A total of 502 articles were identified, of which 23 studies met the inclusion criteria.
Results indicated that a healthy diet improves at least one measure of semen quality, while diets high in lipophilic foods, soy isoflavones, and sweets lower semen quality.
The role of daily nutrient exposure and dietary quality needs to be highlighted in male infertility. Mechanistic studies addressing the responsible underlying mechanisms of action of dietary modifications are highly warranted.

研究表明，适当的营养调整可提高不孕夫妇的自然受孕率。
本研究旨在回顾调查营养与男性不育之间关系的人体试验。
通过检索科学数据库对已发表的人体研究进行全面的系统评价。文章选择按照系统评价和Meta分析的首选报告项目进行。美国饮食协会研究设计与实施清单也用于质量评估。
共识别出502篇文章，其中23项研究符合纳入标准。
结果表明，健康饮食可改善至少一项精液质量指标，而富含亲脂性食物、大豆异黄酮和甜食的饮食会降低精液质量。
日常营养摄入和饮食质量在男性不育中的作用需要得到重视。非常有必要开展机制研究，以探讨饮食调整的相关作用机制。
