Targeting testosterone measurements to patients with type 2 diabetes mellitus and moderate to severe symptomatic erectile dysfunction.

In this study among patients with erectile dysfunction (ED) and type 2 diabetes mellitus, all 25 patients with mild ED were eugonadal. Among patients with moderate ED, 25% were eugonadal while the rest had hypogonadism; while in the severe group only 1 (3%) was eugonadal. This suggests that testosterone measurements in patient with diabetes are better targeted in patients with moderate to severe ED.
