Late-onset 3 beta-ol-hydroxysteroid-dehydrogenase deficiency: prevalence, clinical presentation and endocrine pattern.Acta Eur Fertil. 1985 Nov-Dec; 16(6):427-30.AE
3 patients with late-onset 3 beta-HSD deficiency are described. They presented increased DHEAs/delta 4 ratio either in basal conditions or after ACTH stimulation. All patients were hirsute but only one had increased serum values of delta 4 and total testosterone. However, all patients presented increased serum levels of free testosterone. Two patients had normal menstrual cycles and in one case a secondary PCO was found.
