Previous studies have demonstrated the association between dietary patterns and semen quality indicators, but research on the possible association between animal flesh foods consumption and semen quality is limited. Therefore, this study was conducted to investigate the association between animal flesh foods consumption with semen quality.
In this cross-sectional study, 400 newly-identified (< 6 months) infertile men, as diagnosed by an andrologist, were recruited into the study. Dietary intake was assessed by using a semiquantitative Food Frequency Questionnaire. The total meat consumption was defined as the sum of red meat, poultry, fresh fish, canned fish, processed meats, and organ meats in the diet. A linear mixed model was used to assess the relationship between meat consumption and semen quality indicators of participants.
Consumption of canned fish was inversely related to sperm immotility. Compared with the men in the lowest quartile of canned fish intake, those in the highest quartile had a lower sperm immotility [lowest quartile: 52.5%; (95% CI: 47-57) vs 47.4%; (95% CI: 43-51) P-trend = 0.026]. Similarly, a trend toward an inverse significant association between fresh fish intake and sperm immotility was observed (P-trend = 0.074). In contrast, fresh and canned fish intake was unrelated to other outcomes of sperm quality (P-trend > 0.05). No association was found between consumption of processed red meat, red meat, poultry, and organ meat, and semen quality indicators (P-trend > 0.05).
We found that consumption of canned fish is associated with a lower percentage of immotile sperm, whilst a high consumption of fresh fish increased the percentage of immotile sperm in Iranian infertile men. Further studies are recommended in this regard.
先前的研究已经证明了饮食模式与精液质量指标之间的关联，但关于动物肉类食品摄入与精液质量之间可能存在的关联的研究有限。因此，本研究旨在调查动物肉类食品摄入与精液质量之间的关系。
在这项横断面研究中，我们招募了 400 名新诊断为（<6 个月）不育的男性，这些男性由泌尿科医生诊断。通过半定量食物频率问卷评估饮食摄入。总肉类摄入量定义为饮食中红肉、禽肉、新鲜鱼类、罐装鱼类、加工肉类和动物内脏的总和。线性混合模型用于评估肉类摄入量与参与者精液质量指标之间的关系。
摄入罐装鱼与精子不动性呈负相关。与罐头鱼摄入量最低四分位数的男性相比，摄入量最高四分位数的男性精子不动性较低[最低四分位数：52.5%（95%CI：47-57）与 47.4%（95%CI：43-51），P 趋势=0.026]。同样，摄入新鲜鱼与精子不动性之间也存在负相关的趋势（P 趋势=0.074）。相反，新鲜和罐装鱼的摄入与其他精子质量结果无关（P 趋势>0.05）。摄入加工红肉、红肉、禽肉和动物内脏与精液质量指标之间没有关联（P 趋势>0.05）。
我们发现，摄入罐装鱼与不动精子的百分比较低有关，而大量摄入新鲜鱼则会增加伊朗不育男性不动精子的百分比。在这方面建议进一步研究。
