The incidence of infertility has recently risen. Semen quality is an important male fertility indicator, and dietary factors can affect semen quality. We conducted this systematic review and meta-analysis to determine the effects of healthy dietary patterns on semen quality. A literature search was conducted in 3 databases (Embase, Web of Science and PubMed) on August 21, 2021. The included cross-sectional studies examined the influence of the Mediterranean, Dietary Approaches to Stop Hypertension (DASH), and prudent diet patterns on semen quality parameters; six studies (1244 subjects) were included. By comparing high consumption with low consumption of healthy dietary patterns, the results of the meta-analysis showed significantly higher sperm concentrations (mean difference [MD] = 6.88 × 10 ml, 95% confidence interval [CI]: 1.26 × 10 ml-12.49 × 10 ml; P < 0.05), a significant increase in total sperm count (MD = 16.70 × 10, 95% CI: 2.37 × 10-31.03 × 10; P < 0.05), and a significant increase in progressive sperm motility (MD = 5.85%, 95% CI: 2.59%-9.12%; P < 0.01). The sperm concentration, progressive sperm motility, and total sperm count were significantly higher in men with higher versus lower consumption of healthy dietary patterns. However, the results must be interpreted with caution.
不孕症的发病率最近有所上升。精液质量是男性生育能力的一个重要指标，而饮食因素会影响精液质量。我们进行了这项系统评价和荟萃分析，以确定健康饮食模式对精液质量的影响。我们于 2021 年 8 月 21 日在 3 个数据库（Embase、Web of Science 和 PubMed）中进行了文献检索。纳入的横断面研究调查了地中海饮食、停止高血压的饮食方法（DASH）和谨慎饮食模式对精液质量参数的影响；纳入了 6 项研究（1244 名受试者）。通过比较健康饮食模式的高摄入量与低摄入量，荟萃分析结果显示，精子浓度显著升高（平均差异 [MD] = 6.88×10 ml，95%置信区间 [CI]：1.26×10 ml-12.49×10 ml；P < 0.05），总精子数显著增加（MD = 16.70×10，95% CI：2.37×10-31.03×10；P < 0.05），前向运动精子活力显著增加（MD = 5.85%，95% CI：2.59%-9.12%；P < 0.01）。与低摄入量相比，高摄入量的男性精子浓度、前向运动精子活力和总精子数更高。然而，必须谨慎解释这些结果。
