The role of the pelvic nerves in the postmating abbreviation of behavioral estrus in domestic female rats was investigated. Mating during a period of 40 min at the beginning of hormonally induced estrus in spayed female rats resulted in a rapid decrease in receptivity as measured hourly by the lordosis response. Moreover, the length of the receptive period was significantly shortened by mating at the start of the period. Bilateral pelvic nerve transection completely abolished these effects of mating. Continuous exposure to sexually active males throughout the period of receptivity resulted in a more pronounced decline in receptivity but again was without effect in pelvectomized females. Apparently genital stimuli mediated by the pelvic nerves are responsible for the postcopulatory decrease in receptive behavior in the female rat.
研究了盆腔神经在雌性家鼠交配后行为性发情缩短中的作用。在切除卵巢的雌性大鼠激素诱导发情开始后的40分钟内进行交配，通过脊柱前凸反应每小时测量一次，结果显示接受性迅速下降。此外，在发情期开始时交配显著缩短了接受期的长度。双侧盆腔神经切断完全消除了交配的这些影响。在整个接受期持续接触性活跃的雄性会导致接受性更明显的下降，但对盆腔神经切断的雌性大鼠同样没有影响。显然，由盆腔神经介导的生殖器刺激是雌性大鼠交配后接受行为减少的原因。
