The effect of bilateral pelvic, hypogastric, or pudendal neurectomy on oxytocin-induced facilitation of lordosis behavior was examined in ovariectomized, estrogen, and progesterone primed female rats. Oxytocin-induced facilitation of lordosis behavior was significantly decreased following bilateral pelvic, or combined bilateral pelvic and hypogastric neurectomy. Hypogastric only or pudendal only neurectomy had no effect on the facilitation of lordosis behavior after systemic administration of oxytocin. These results suggest that the integrity of the pelvic nerve is necessary and sufficient to mediate the stimulatory effects of systemically administered oxytocin on receptivity.
