Detailed Description:

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by age.

Patients are randomly assigned to androgen replacement therapy with daily dehydroepiandrosterone (DHEA) or placebo for 6 months. All patients may receive 6 additional months of DHEA following randomized therapy.

Women on hormonal replacement therapy may receive concurrent conjugated estrogens or oral medroxyprogesterone.
