Overweight and obese men have been reported to have lower sperm quality. The aim of this study was to evaluate, whether body mass index (BMI) is related to changes in semen parameters. In a cross-sectional study, sperm parameters were reviewed in 852 normal, healthy men, of reproductive age (25-50). BMI was divided into four groups: underweight, normal, overweight and obese. Sperm concentration of overweight and obese men were 63 and 62, respectively, which were lower than subjects with normal BMI (71). Total sperm count and sperm motility in overweight and obese men were significantly lower than men with normal BMI too. Sperm morphology in study groups was similar. The results revealed a significant inverse correlation between the BMI and the sperm parameters.
超重和肥胖的男性被报道精子质量较低。本研究的目的是评估体重指数（BMI）是否与精液参数的变化有关。在一项横断面研究中，对 852 名处于生育年龄（25-50 岁）的正常健康男性的精子参数进行了回顾性分析。BMI 分为四组：消瘦、正常、超重和肥胖。超重和肥胖男性的精子浓度分别为 63 和 62，低于正常 BMI 组的 71。超重和肥胖男性的总精子数和精子活力也明显低于正常 BMI 组。研究组的精子形态相似。结果表明，BMI 与精子参数呈显著负相关。
