Androgens, bone mineral content and hyperostosis frontalis interna in pre-menopausal women.

Greater than normal bone mineral content, bone width of the radius measured by photon absorptiometry and bone mineral content to bone width ratio found in women with hyperostosis frontalis interna pointed on a generalized alteration of the skeletal system. An increase in serum dehydroepiandosterone, its sulphate and testosterone levels and a significant correlation between serum free dehydroepiandosterone and bone mineral content in subjects without any sign of hirsutism or obesity suggested an involvement of androgens in pathogenesis of this metabolic bone disorder.
