[Morphological studies of follicular atresia in the estrogen syndrome of swine].
Studied were 86 ovaries of sows with clinically manifested estrogenic syndrome and of ten controls. Strongly expressed atresia was found of the follicles in the ovaries of sows exhibiting estrogenic syndrome. On the basis of the most frequently manifested changes as many as five types of follicular atresia were differentiated. The luteinization of newly ovulated tertiary follicles observed in that case represented a particular phenomenon. The changes observed in most cases were characterized by fatty degeneration. It is believed that the persistence of the estrogenic syndrome could lead to complete and irreversible sterility of sows.
