The effect of castration on the urinary excretion of a gonadotropin-inhibiting substance was studied in male albino rats. Ovulation induced with PMS and HCC was not inhibited in mice which received a heated extract prepared from the urine of castrated rats, while the ovulation was inhibited in mice given a heated extract from the urine of intact rats. This finding indicates that the excretion of a gonadotropin-inhibitor is strongly suppressed in the urine of the rats which are castrated. Administration of testosterone to the castrated rats exerted no effect on the decreased excretion of the inhibitor. The present observations and the results obtained previously suggest that the pituitary and the testes are involved in the secretion of a gonadotropin-inhibitor from the pineal.
