Abstract: | "Posterior hypophysis homogenates of female rats stimulated with epinephrine subcutaneously contain a pheromonal factor that increments significantly the incidence of fertile coitus after having been placed in the oronasal groove of rats in proestro (69.2% fertile coitus vs. 36.6% of control). These same homogenates obtained from spayed rats increment reproductive activity even more (80.0% fertile coitus). The homogenates do not act by an intraperitoneal route. Male rats under the effect of high doses of D,L-propranolol reduce reproductive activity (21.2% fertile coitus). This effect is counteracted by posterior hypophysis homogenates from female rats stimulated with epinephrine, placed in the oronasal groove (72.2% fertile coitus). The homogenates of anterior hypophysis do not increase the reproductive capacity of rats in proestro, and do not modify the propranolol effects in male rats" |
