Notes for this study:
180 men with erectile dysfunction took 1.5 g/d of Tribulus (divided into 3 equal doses) or placebo for 12 weeks. IIEF score, the primary outcome, improved significantly more in the intervention group than the placebo group at 4, 8, and 12 weeks. A significantly higher percentage of participants in the intervention group reported improved erections. There was no significant difference between the groups for levels of testosterone, free testosterone, DHEA-S or SHBG. Total cholesterol, LDL-C, HDL-C, triglycerides, and blood pressure were unchanged.
