Reversible insensitivity to androgens in men with untreated gluten enteropathy

Abstract

Plasma androgen and gonadotrophin concentrations have been measured before and during treatment of 23 men with gluten enteropathy. Before treatment, there was marked rise in total plasma-testosterone, free testosterone concentration (as assessed by the free testosterone index), and plasma-luteinising-hormone concentration. In contrast, 5 alpha-dihydrotestosterone concentrations were lower than normal. All these abnormalities reverted towards normal with successful treatment of the jejunal mucosal lesion. These data are consistent with a reversible tissue resistance to circulating plasma-testosterone in men with gluten enteropathy and subtotal villous atrophy.
