70 men with erectile dysfunction and partial androgen deficiency took either 750 mg/d of Tribulus (divided into 3 equal doses) or placebo for 3 months. Participants in the Tribulus group saw a significant increase in aspartate transaminase, total testosterone, and erectile function relative to baseline. There was a significant increase in prostate-specific antigen and no significant change in alanine transaminase or the international prostate symptom score. There were no between-group comparisons, however, the placebo group saw no significant changes in any parameter.
