[Testosterone, FSH and LH level in the serum of patients with prostatic neoplasms, treated with female hormones].

Testosterone, FSH and LH were measured in serum of patients suffering from prostatic carcinoma. The efficacy of treatment with 1 mg diethylstilbestrol/d (Cyren A) was shown by suppressed serum levels of testosterone, FSH and LH comparable to castration in a follow-up until 560 weeks after beginning of therapy. Prolactin was raised in all patients under treatment.
