Sexual impotence: studies of the hypothalamic-pituitary-thyroid axis and the effect of oral thyrotropin-releasing factor.

Thyrotropin-releasing factor was given orally to 12 impotent patients in a dose of 43 mg daily for 4 weeks in a double-blind crossover technique and compared with placebo. TRF showed no beneficial effect over placebo. In these patients, thyroid function and the hypothalamic-pituitary-thyroid axis were examined by measuring T3, T4, and TSH before and after the TRF test. There were no pathological findings for patients included in this study.
