title: [Study of the role or weaning and of androgens in the determinism of adrenal sexual dimorphism at the moment of puberty in the guinea pig].
abstract: Sexual dimorphism of the adrenal, which appears at puberty in guinea-pig, is not the fact of weaning. This dimorphism is suppressed by castration in male or injection of testosterone in female. Testis androgens are the cause of the lower values of plasma and adrenal cortisol concentrations and of adrenal weight noticed in male compared with female between days 20 and 90 of postnatal life.
