OESTRUS-ACCELERATING PHEROMONE OF MICE: ASSAY, ANDROGEN-DEPENDENCY AND PRESENCE IN BLADDER URINE

Abstract

Summary. Two methods for the assay of a pheromone produced by male mice were compared. Using these methods it was shown that the pheromone was present in urine from males of two inbred strains and from androgenized, spayed females, but not in urine from castrate males. It was present in urine collected directly from the bladder free from any accessory gland secretion.
