title: [Plasma, testicular, and adrenal cortex levels of androgens in the perinatal period and determination of neonatal hypertestosteronemia in guinea pigs].
abstract: The perinatal period is characterized in the male faetus and new-born Guinea-Pig by a prenatal increase in testis testosterone and by a neonatal peak in plasma testosterone. This transient rise in plasma testosterone is testis dependent and light dependent at birth.
