Reduction of growth hormone secretion following clomiphene administration

Serial plasma growth hormone (GH) concentrations were measured every 20 min for 24 hr before and after the administration of clomiphene citrate (100 mg/day for 7 days) to four healthy young adult male subjects. The number of GH secretory episodes and the magnitude of the peak plasma concentrations during both wakefulness and sleep were decreased after the clomiphene treatment periods.
