Superfoetation of Mice

Nature volume 227, pages 1343–1344 (1970)Cite this article

Abstract

DURING experiments in our laboratory on the effects of environmental temperature on mice, anomalous gestations have been observed. We give here examples of the birth of litters too soon after a previous litter to be the result of a normal post-partum insemination. In this account, by “superfoetation” we mean the occurrence in the same animal of two pregnancies at different stages of development1.
