title: Impotence secondary to postpuberal hypogonadism.
abstract: We studied 4 patients who were under consultation for secondary 'impotence coeundi' and who had had normal puberal development (degree V in the Tanner's scale). 2 of them had children. In the diverse diagnostic attempts, basal deficits of FSH, LH and testosterone were repeatedly confirmed. Stimulation with HCG was positive. Stimulation with Gn-RH did not modify the basal deficient values. Stimulation with clomiphene in 1 case was also negative. The determinations of ACTH, TSH, metopirone test and PBI were normal. In the spermiograms there  was oligoasthenozoospermia. We have not found antecedents that justify the hormonal insufficiency, thus we consider that it is a selective deficit of FSH and LH and of hypothalamic or pituitary postpuberal idiopathic genesis. Sexual potency was quickly regained when the patients were treated with HCG. In every case the dose was adjusted to allow therapeutics.
