title: The effect of male body mass index on sperm parameters.
abstract: 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.
