The aim of this cross-sectional analysis is to investigate the associations between the adherence to the Mediterranean Diet (MD) and semen quality parameters. To assess the adherence to the MD, the Trichopoulou score was used. Semen parameters were assessed as described in the 2010 WHO's report and the results are showed across tertiles of MD adherence. A total of 106 participants were included. Compared to those in the lowest MD adherence tertile, participants in the top tertile had statistically significant higher BMI and waist circumference and consumed more energy, and also had statistically significant higher semen pH, and total sperm motility and progressive sperm motility percentages, and lower sperm immotility percentages. Moreover, percentage of total and progressive motility were significantly higher among those subjects in the higher adherence to MD in comparison with those in low-medium adherence category. The multivariable linear regression models evaluating the relationship between the sperm quality parameters and tertiles of MD adherence adjusted by age, energy and BMI showed that compared with the lowest tertile, men in the highest tertile had a higher percentage of total sperm motility [β non-standardized coefficient = 12.785]. These findings suggest that adherence to the MD was positively associated with sperm motility.
本横断面分析旨在研究地中海饮食（MD）的依从性与精液质量参数之间的关联。为了评估 MD 的依从性，使用 Trichopoulou 评分。精液参数按照 2010 年世界卫生组织的报告进行评估，并按 MD 依从性的三分位显示结果。共纳入 106 名参与者。与 MD 依从性最低三分位组相比，最高三分位组的参与者 BMI 和腰围显著较高，摄入的能量更多，且精液 pH 值、总精子活力和前向运动精子比例显著较高，精子不动比例显著较低。此外，与中低 MD 依从性类别相比，较高 MD 依从性的参与者中总活力和前向运动活力的百分比显著更高。通过年龄、能量和 BMI 调整 MD 依从性三分位与精子质量参数之间关系的多变量线性回归模型显示，与最低三分位相比，最高三分位的男性总精子活力百分比更高[β 未标准化系数=12.785]。这些发现表明，MD 的依从性与精子活力呈正相关。
