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

Abstract
Two methods for the assay of a pheromone produced by male mice were compared. Using these methods pheromone was demonstrated present in urine from males of 2 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.
