Pituitary-gonadal response to acute I.M. stimulation with clomiphene citrate in normal men

HR Miechi, D Turner, A Guitelman, NJ Aparicio and L Schwarzstein

In order to asses the effect of acute i.m. injection of clomiphene citrate (CC) on LH, FSH, and testosterone (T) secretion, five normal, fertile men received 5 mg of the drug dissolved in 2 ml 0.9% saline, while a further five were injected 10 mg of the same preparation. All tests were performed at 8 a.m. Blood samples were drawn at 0, 30, 60, 120 and 180 minutes of the injection. Serum LH, FSH, and T values were determined by the double antibody radioimmunoassay technique. A significant rise of the LH, FSH, and T levels was obtained in both groups. Peak LH values were obtained at 30 minutes (average), whereas FSH and T peaks occurred at 60 minutes. The 180-minute values were similar to basal. The results seem to indicate that intramsucularly administered CC could be useful, as a rapid test, in evaluating the function of the hypothalamic-pituitary-gonadal axis.
