Spermatogenic Disturbance in Boars Infected Spontaneously with Japanese Encephalitis Virus

Abstract

Five young boars manifested pyrexia and oscheal enlargement when they, showed an increase in titer of HI antibody against Japanese encephalitis. As a result, dysspermia or aspermia, a decrease in count of viable sperms, and an increase in number of abnormal sperms were noticed. The testis was atrophic and had spoke-like foci on its cut surface. Spermatogenesis was not observed in these foci, but was in the normal part of the testis.
