The aim of this study was to assess the associations of intake of different types of meat with semen parameters and reproductive hormones in healthy young men. This cross-sectional study included 206 men, 18-23 years, from Southern Spain. All men completed a validated FFQ, underwent a physical examination, and provided blood and semen samples. Multivariable linear regression was used to evaluate the associations between meat intake with semen quality parameters and reproductive hormones. Total meat intake was unrelated to semen quality or reproductive hormone levels. When subgroups of meat were separately considered, however, shellfish intake was positively related to progressive motility. The adjusted percentages of progressively motile spermatozoa for men in increasing quartiles of shellfish intake were 45·2, 42·0, 49·4 and 53·2 % with a significant linear trend across quartiles (P trend≤0·001). In contrast, men who consumed organ meats had significantly lower progressive sperm motility (51·5 v. 42·8 %; P = 0·001) and higher luteinising hormone levels (4·0 v. 4·6 IU/l; P = 0·03) compared with men who did not consume organ meats. Intake of shellfish and organ meats was low in this population, however. Given the scarcity of data on the relation between specific types of meat with semen quality and reproductive hormone levels, additional research is needed to confirm or refute these findings.
本研究旨在评估不同类型的肉类摄入量与健康年轻男性的精液参数和生殖激素之间的关联。这项横断面研究纳入了来自西班牙南部的 206 名 18-23 岁的男性。所有男性均完成了一份经过验证的 FFQ 问卷，接受了体检，并提供了血液和精液样本。多变量线性回归用于评估肉类摄入量与精液质量参数和生殖激素之间的关系。总的肉类摄入量与精液质量或生殖激素水平无关。然而，当分别考虑肉类的亚组时，贝类摄入量与前向运动精子呈正相关。按贝类摄入量递增的四分位数，前向运动精子的比例分别为 45.2%、42.0%、49.4%和 53.2%，四分位数之间存在显著的线性趋势（P 趋势≤0.001）。相比之下，摄入内脏的男性的前向运动精子活力显著较低（51.5%比 42.8%；P=0.001），促黄体生成激素水平显著较高（4.0 比 4.6 IU/l；P=0.03）。然而，该人群中贝类和内脏的摄入量较低。鉴于关于特定类型的肉类与精液质量和生殖激素水平之间关系的数据稀缺，需要进一步研究来证实或反驳这些发现。
