Lactating pregnant gerbils in which one oviduct was ligated during early pregnancy were used on Day 6-14 p.c. as recipients for eggs (morulae and blastocysts) recovered on Day 6-12 p.c. from lactating donors. Eggs were transferred to the ligated (experimental) horn and the litter was removed. About half of the recipients had implantations in the non-ligated (control) horn 15 days after litter removal. Of these 40 females, 37 had implantations in the experimental horn and 32 had some normal fetuses present. Of 179 eggs transferred into the ligated uteri, 61% implanted and 41% developed into normal fetuses. The time after copulation of recipient and donor did not appear to influence the number of implantations or post-implantation development of the transferred eggs.
在妊娠早期将一侧输卵管结扎的哺乳期怀孕沙鼠，在妊娠第6至14天用作受体，接受从哺乳期供体在妊娠第6至12天回收的卵（桑椹胚和囊胚）。将卵转移到结扎的（实验性）子宫角，并取出窝仔。在取出窝仔15天后，约一半的受体在未结扎的（对照）子宫角有着床。在这40只雌性中，37只在实验性子宫角有着床，32只有一些正常胎儿。在转移到结扎子宫的179个卵中，61%着床，41%发育成正常胎儿。受体和供体交配后的时间似乎不影响转移卵的着床数量或着床后发育。
