The uterine tube, uterus and ovaries structure was studied on the material taken from 14 healthy 48 to 60 days old piglets. The postnatal histological changes in uterine tube, infundibulum, ampulla, isthmus, uterus and ovaries were studied with LM and TEM. 48-60 days old piglets have in the uterine tube eoithelium ciliated and non-ciliated cells. Typical ultrastructural elements of ciliated cells were present. The structural development of non-ciliated and ciliated cells was different. The results of our investigation prove that differentiation of uterine tube epithelial cells in 2-3 months old piglets into secretory and ciliated cells has not terminated. The microstructure of uterus wall in 53 days old piglets is similar to that of sow, but in some uterine glands we have detected cambial cells. The influence of female sex hormones on the postnatal development of oviductal epithelial cells is discussed
