title: Antiandrogenic effects of spironolactone: hormonal and ultrastructural studies in dogs and men.
abstract: A decrease in the level of plasma testosterone and an increase in the level of plasma progesterone were noted after spironolactone had been administered for 20 days in 5 patients with prostatic carcinoma, as well as in 8 male dogs. Electron microscopic observation disclosed myelin-like bodies in the cytoplasm of Leydig and adrenocortical cells in dogs, contributing to a resolution of the mode of antiandrogenic action of spironolactone.
