The etiology of diminished sperm quality in about 30% of male infertility cases generally remains unexplained. Some studies have suggested that specific nutritional factors can affect semen quality. The aim of this study was to evaluate an association between dietary patterns (DPs) and the risk of abnormal semen quality parameters in men. This cross-sectional study was carried out in 114 men aged 20⁻55 years from Poland. Semen parameters were assessed via computer-aided semen. Diet was assessed by a food frequency questionnaire (FFQ). DPs were derived using Principal Component Analysis (PCA). Two DPs were derived: Pro-healthy and Western. After adjusting for potential confounders, the risk of abnormal progressive motility was significantly higher in the middle (OR: 2.89, 95% CI: 1.03⁻8.09) and upper (OR: 7.78, 95% CI: 1.52⁻15.06) tertiles of the Western DP. A trend for increased risk of the abnormal total count, progressive motility, and morphology (-trend < 0.050) was found in Western DP. To conclude, the Western DP may increase the risk of abnormal semen parameters, whereas no association was found in the case of Pro-healthy DP. These findings stand in contrast to an increasing number of research findings indicating a positive relation between intake of healthy foods or diet and semen quality parameters. The results highlight the need to study whether modifications in diet and lifestyle factors improve semen quality.
约 30%男性不育病例的精子质量下降的病因通常仍未得到解释。一些研究表明，特定的营养因素可能会影响精液质量。本研究旨在评估饮食模式（DPs）与男性异常精液质量参数风险之间的关联。这是一项在波兰进行的横断面研究，共纳入了 114 名年龄在 20-55 岁的男性。通过计算机辅助精液分析评估精液参数，通过食物频率问卷（FFQ）评估饮食。使用主成分分析（PCA）得出 DPs。得出了两种 DPs：健康促进型和西式。调整潜在混杂因素后，西式 DP 中中等（OR：2.89，95%CI：1.03-8.09）和较高（OR：7.78，95%CI：1.52-15.06）三分位的异常前向运动风险显著增加。西式 DP 中异常总计数、前向运动和形态学的风险呈增加趋势（-趋势<0.050）。总之，西式 DP 可能会增加异常精液参数的风险，而健康促进型 DP 则没有这种关联。这些发现与越来越多的研究结果形成对比，这些结果表明健康食物或饮食的摄入与精液质量参数之间存在正相关关系。这些结果强调了需要研究饮食和生活方式因素的改变是否能改善精液质量。
