Summary The ultrastructure of the rat uterine luminal epithelium has been examined during normal pregnancy, pseudopregnancy, lactation and lactation-pregnancy, all being conditions when a blastocyst is known to be able to implant. In all four groups of animals the epithelium passes through three characteristic and structurally similar states, namely a pre-attachment state, an attachment state and a postattachment state. The attachment state is characterized by a close contact between apposing luminal surfaces of the epithelium. It is concluded that implantation in an undamaged uterus claims a sequence of certain changes in the uterine luminal epithelium, and that the blastocyst attachment occurs within the early part of that period when the luminal epithelium is in the attachment state.
