Existing therapeutics to enhance male sexual health are limited by factors that include responsiveness, adherence and adverse effects. As the population ages, safe and effective interventions that preserve male sexual function are needed. Published research suggests that various preparations of Kaempferia parviflora, a plant in the Zingiberaceae （ginger） family, support cardiovascular health and may ameliorate erectile function. Objective： The aim of this study was to examine the effects of KaempMaxTM, an ethanol extract of the K. parvi]lora rhizome, on erectile function in healthy middle-aged and older men. Design, setting, participants and interventions： We conducted an open-label, one-arm study on 14 generally healthy males aged 50-68 years with self-reported mild erectile dysfunction, who were not using pre- scription treatments. Participants took 100 mg KaempMaxTM daily for 30 days. Main outcome measures： Evaluations were conducted at baseline and on the final study assessment. Primary efficacy analyses included the International Index of Erectile Function （IIEF）; secondary efficacy analyses included the Global Assessment Question about erectile function. Results： Thirteen participants completed the 30-day study. Supplementation with KaempMaxTM resulted in statistically significant improvements in erectile function, intercourse satisfaction and total scores on the IIEF questionnaire. KaempMaxTM was well tolerated and exhibited an excellent safety profile. Conclusion： Our results suggest that KaempMaxTM may improve erectile function in healthy middle-aged and older men. While the effects were not as pronounced as what might be seen with prescription med- ication, most participants found them satisfactory. Additional, longer and placebo-controlled clinical tri- als will be needed. Trial registration： Clinicaltrials.gov identifier Ncr03389867.展开更多
