Abstract
The Authors have evaluated the relationship between the secretion of dehydroepiandrosterone sulfate (DHA-S) by the adrenal glands and by the gonads in a group of prepubertal and pubertal subjects (“short normal”), both males and females. In the male subjects a hCG test and an ACTH test were performed; in the female subjects only the latter test was carried out. The behavior of DHA-S under basal conditions was also assessed in both sexes and related to bone age and chronological age in the prepubertal period and during the early stages of puberty. Plasma levels of DHA-S in both sexes increase progressively with chronological age and bone age. A negative correlation was found between DHA-S and bone delay (expressed in percent relative to chronological age) in prepubertal subjects, both males and females. A significant increase in DHA-S after hCG stimulation was found both in prepubertal and pubertakboys. After ACTH stimulation DHA-S increased significantly in prepubertal and pubertal males and females; throughout the test no difference was found between prepubertal and pubertal subjects nor between male and female subjects. Our data confirm that DHA-S is produced both by the adrenals and by the testes.
