Salivary androgens in hirsutism: are they of use in routine evaluation?
In the biochemical evaluation of hirsutism, 50% or less of patients have an elevated total serum testosterone. Recent work has suggested that measuring salivary testosterone or a derived serum 'free testosterone index' may be of use in the evaluation of hyperandrogenism. We have measured serum total, derived serum free indices and salivary concentrations of testosterone and 5 alpha-dihydrotestosterone in an unselected group of hirsute patients in order to assess their value in the routine evaluation of hirsutism. The assays were performed using a novel oxidation procedure to overcome the need for chromatographic separation. The 'free testosterone index' gave the best discrimination. Salivary androgen concentrations were comparatively poor and cannot be recommended for routine use.
