High bone density in hyperandrogenic women: effect of gonadotropin-releasing hormone agonist alone or in conjunction with estrogen-progestin replacement.

We studied 20 hirsute patients with high levels of serum testosterone (T), calculated free T, androstenedione, and dehydroepiandrosterone sulfate and 19 age-matched nonhirsute normoandrogenic control women. The bone mineral density (BMD) in the lumbar spine, femoral neck, and trochanter major region in hirsute patients was higher than that in the controls. BMD in the lumbar spine and proximal femur correlated positively with the body mass index and with serum T and free T in hyperandrogenic women and the whole study group, but not with serum androstenedione or dehydroepiandrosterone sulfate levels.
