Pregnancy block caused by exposure of mated female mice to a strange male was significantly reduced by bilateral destruction of the vomeronasal organ. Treatment of newly mated females with alpha-bromocriptine also produced pregnancy block. Pregnancy block also occurred in mated females exposed to strange male odours, but the blastocysts which had failed to implant were still present in the uterus and were viable for up to 15 days after mating. Implantation was induced in such mice by administration of exogenous progesterone and oestradiol.
将交配过的雌性小鼠暴露于陌生雄性小鼠导致的妊娠阻断，可通过双侧破坏犁鼻器而显著减轻。用α-溴隐亭处理刚交配的雌性小鼠也会产生妊娠阻断。暴露于陌生雄性气味的交配过的雌性小鼠也会出现妊娠阻断，但未能着床的囊胚仍存在于子宫中，并且在交配后长达15天内仍具有活力。通过给予外源性孕酮和雌二醇可诱导此类小鼠着床。
