Salivary testosterone in prostatic carcinoma.

Testosterone concentrations in saliva were measured in 13 patients with prostatic carcinoma after surgical or medical (diethylstilboestrol or Estracyt) orchiectomy. The salivary testosterone values in these patients were significantly lower than in normal males but not significantly different from those in normal females. The salivary testosterone concentrations were measured for 6 consecutive months and did not vary significantly from month to month. The results suggest that the measurement of salivary testosterone concentrations could be useful in evaluating the androgenic function of patients with prostatic carcinoma after medical or surgical orchiectomy.
