title: Morphological changes in the trophoblast, uterus and corpus luteum during delayed implantation and implantation in the western spotted skunk.
abstract: Morphological interactions of tropholbast and uterus from stages of preimplantation and implantation were studied in 14 western spotted skunks. In addition, the granulosa lutein cells and plasma progesterone levels were studied. In animals several days from implantation the height of epithelial cells decreased, but began to increase in animals approaching implantation. During the preimplantation period a few leucocytes infiltrated the epithelium, but in animals just prior to implantation many leucocytes infiltrated the epithelium.
