[Gonadotropic function of the pituitary gland and the antigonadotropin activity in healthy girls].

This clinical and laboratory investigation is devoted to the study of the levels and correlation between the total gonadotropins and antigonadotropin factors excreted in the urine of 10-18-year-old girls. There was found a correlation between the excretion of total gonadotropins and the concentration of their inhibitors. Periods of the greatest fall of the antigonadotropin level corresponded to the peaks of gonadotropin activity.
