The aim of the study was a histological evaluation of mucosa of the oviduct and uterus, regarding cystic ovarian degeneration in sows. Materials for the evaluation were received after the slaughtering of 294 sows at the age of two to five years. The sows were eliminated from breeding and culled due to disorders such as: anoestrus after weaning of piglets, return of oestrus, small litter size, high number of parturitions, bad condition after lactation, and age. Twenty of the 294 sows (6.8%) had cysts on the ovaries. The sows were divided into two groups: group 1 (12 sows) with polycystic ovaries and group 2 (8 sows) with simple cysts, which occurred unilaterally (3 sows) or bilaterally (5 sows). The studies demonstrated different kinds of ovarian cysts and structural changes in ovarian cortex, such as decreasing number of ovarian follicles of all generations and increase in follicular atresia. The histological state of tissues and changes of mucosa of the oviduct and uterus, regarding polycystic ovaries or single cysts on ovaries were compared. The single follicular cysts were not accompanied with important changes in the reproductive system. In the case of polycystic ovaries, the presence of cyst was connected with the occurrence of morphological changes in the endothelium of the oviduct and uterus, which could have been a reason of persistent infertility in pigs. An increase in the number of secretory cells with simultaneous decrease in ciliated ones, both in the ampulla and isthmus and covering the epithelium by secretions were observed in the oviduct. In our studies, we observed increasing proliferation of both glandular epithelium and surface epithelium. The terminal portion of the uterine glands was cystic dilated with remaining secretions. Hypersecretion of superficial epithelium was noted.
