Abstract
Dehydroepiandrosterone (DHEA) and its sulfate ester, DHEAS, are the most abundant steroids in the human circulation, although their exact biological significance is not completely understood. DHEA(S) levels are high in fetal life, decrease after birth, and show a marked pubertal increase to a maximal level during young adulthood. In healthy adults, DHEAS levels decline to 10–20% of peak levels by age 70 yr. This review summarizes information concerning the role of DHEA in skeletal physiology, including modulation of the skeletal insulin-like growth factor regulatory system, and its effects on secretion of proresorptive cytokines. The pattern of secretion of DHEA throughout the life cycle is discussed, as well as its potential usefulness in specific disease states as an agent with anabolic and antiosteolyic effects on bone.
