title: Hormonal regulation of chemosignals of female mice that elicit ultrasonic vocalizations from males.
abstract: Two experiments examined the properties of vaginal, facial, salivary, and urinary odors from female house mice to elicit ultrasonic vocalizations from male mice. Experiment 1 demonstrated that facial and salivary secretions from hypophysectomized females were significantly less effective in eliciting ultrasonic vocalizations from male mice than were these same secretions from either intact or ovariectomized females. Thus the hormonal control of chemosignals from these two sources paralleled earlier findings of pituitary rather than ovarian regulation of the urinary chemosignal that elicits ultrasounds. In contrast, ovariectomy and hypophysectomy seemed to have similar depressive effects upon the vaginal cue that elicits ultrasounds. Experiment 2 demonstrated that long-term ovariectomy (8 or 9 months) diminished the effectiveness of female saliva, but not urine, to elicit vocalizations. The apparent dissociation of the hormonal regulation of salivary, vaginal, and urinary chemosignals suggests that multiple chemosignals may possess the property of eliciting male vocalizations.
