We read with interest the article of Shayeb et al. which reports an association between male body mass index (BMI) and semen quality (Shayeb et al., 2011). Using logistic regression the authors imply obese men are more likely to have lower semen volumes and higher abnormal sperm morphologies than men with normal BMI.There are several concerns and omissions about this communication that require further discussion. Conditions that may have an impact on semen quality (e.g. diabetes), need further evaluation in this population. Diabetes is a serious health condition often associated with obesity. Evidence from several studies suggests that obesity and weight gain are related to an increased risk of diabetes (Ford et al., 1997; Resnick et al., 2000). Recent findings have shown that diabetes induces subtle molecular changes that influence sperm quality and function (Mallidis et al., 2011).

机译：我们感兴趣地阅读了Shayeb等人的文章。该研究报告了男性体重指数（BMI）与精液质量之间的相关性（Shayeb et al。，2011）。作者使用逻辑回归分析表明，肥胖男性比BMI正常的男性更可能具有较低的精液量和较高的异常精子形态，对此沟通存在一些担忧和遗漏，需要进一步讨论。可能影响精液质量的疾病（例如糖尿病），需要对该人群进行进一步评估。糖尿病是一种严重的健康状况，通常与肥胖有关。一些研究的证据表明，肥胖和体重增加与糖尿病风险增加有关（Ford等，1997; Resnick等，2000）。最近的发现表明，糖尿病会引起影响精子质量和功能的细微分子变化（Mallidis等，2011）。
