A brief literature review shows that Yohimbina gave 45-65% satisfactory results when used to treat erectile deficit. The author then makes a retrospective evaluation of 58 patients, comparing them with a control group of 12 patients treated with a placebo (vit. A+E). The effectiveness of Yohimbina, prescribed with magistral prescription, proved to be between 40 and 70%, depending on the patient's age and type of erectile deficit, and was certainly superior to the placebo.
