Insertion of a unilateral intrauterine device (IUD) on day 1 pc in rabbits and rats or day 2 pc in mice is found to interrupt pregnancy in the device-bearing uterine horn, but does not affect blastocyst implantation or fetal development of the contralateral side. It is also evident that following surgical ablation of the ovary of the non-IUD side, the ovary of the IUD-bearing side can effectively maintain pregnancy and fetal growth as in controls. The possible mode of action of the IUD has been discussed.
在兔和大鼠的产后第1天或小鼠的产后第2天插入单侧宫内节育器（IUD），发现可中断带器子宫角的妊娠，但不影响对侧的胚泡着床或胎儿发育。同样明显的是，在对侧卵巢进行手术切除后，带器侧的卵巢能够像对照组一样有效地维持妊娠和胎儿生长。文中已讨论了宫内节育器可能的作用方式。
