title: Effects of testosterone upon the chest-rubbing behavior of Galago crassicaudatus umbrosus.
abstract: The chest-rubbing behavior of 8 male greater galagos was studied. Castration of 4 males resulted in a sharp decrease in chest-marking, while testosterone replacement therapy resulted in an increased frequency. The 4 male controls generally maintained a stable relationship between chest-rubbing frequency and serum testosterone levels. Results of the study indicate that while chest-rubbing frequency may initially vary individually in relation to testosterone levels, drastic fluctuations in serum testosterone are accompanied by a corresponding fluctuation in chest-rubbing behavior.
