[Normal cyclical morphology of the endometrium and ovary of swine].

43 sows selected from registered herds without reproductive problems were slaughtered on fixed days of the sexual cycle. The macroscopic appearance of the endometrium and of the ovaries was judged. Endometrial samples from the corpus uteri as well as from the middle part and apex of uterine horns were then examined histologically (optical microscopy, transmission and scanning electron microscopy) especially concerning the epithelia of surface and glands. The variation of endometrial and ovarian morphology during the sexual cycle is described, presented in a summarizing table, documented by illustration and discussed.
