A series of experiments based on 150 newly mated, uni- and multi-parous Mongolian gerbils provided no evidence for the existence of pregnancy blocking due to a strangle male effect. The reduced level of fertility observed was attributed to stressful factors at critical times in the pregnancy. Treatment with 10 i.u. PMSG on the day following mating interrupted pregnancy and the majority of females mated again within 4 days.
基于150只新交配的单胎和多胎蒙古沙鼠进行的一系列实验，没有提供因雄性勒颈效应而导致妊娠阻断存在的证据。观察到的生育力降低归因于妊娠关键时期的应激因素。交配后第二天用10国际单位孕马血清促性腺激素（PMSG）治疗会中断妊娠，并且大多数雌性在4天内再次交配。
