In a randomized controlled trial 145 sexually active overweight/obese men received either a male only SHED-IT (Self Help Exercise and Diet Using IT) weight loss program or a wait-list control. Erectile function (IIEF-5) was compared between men in the active intervention versus controls. IIEF-5 was assessed at baseline, 3 months (post-intervention) and 6 months (3-month follow-up). Intention-to-treat analysis revealed a significant intervention effect for erectile function (p = 0.018) at 6 months (+1.4; 95% CI 0.3,2.4; d = 0.32). A minimal contact, gender-tailored weight loss program significantly improved men's erectile function. Further studies evaluating change in erectile function with weight loss are warranted.
在一项随机对照试验中，145名性活跃的超重/肥胖男性接受了仅针对男性的SHED-IT（利用信息技术进行自助锻炼和饮食）减肥计划或等待名单对照。对积极干预组与对照组男性的勃起功能（国际勃起功能指数-5，IIEF-5）进行了比较。在基线、3个月（干预后）和6个月（3个月随访）时评估IIEF-5。意向性分析显示，在6个月时勃起功能有显著的干预效果（p = 0.018）（增加1.4；95%可信区间0.3,2.4；d = 0.32）。一个最低限度接触、针对性别的减肥计划显著改善了男性的勃起功能。有必要进行进一步研究以评估减肥对勃起功能的影响变化。
