Hence a study on the pathological conditions of these organs might give an approximate idea of the nature and prevalence of sterility conditions in male goats. The present study was taken up with this object in view.
Thousand pairs of testicles and epididymis of bucks, aged 6-18 months were collected at random from the abattoir and examined. The organs which revealed gross lesions and those which were suspected to be affected were subjected to detailed histopathological studies.
Out of the thousand pairs of organs examined, 174 (17.4%) revealed various pathological lesions. The following pathological conditions were observed during the course of the present study: Testicular hypoplasia (5.8%), Cryptorchidism (2.9%), Ectopic testis (0.4%), Testicular degeneration (0.4%), Adhesion with tunics (1.8%), Testicular strophy (1.3%), Testicular haemorrhage (0.1%), Male pseudo hermaphroditism (0.1%), spermiostasis (1.1%) Spermatic granuloma (0.1%), Epididymal haemorrhage (0.4%), Epididymal melanosis (4.3%).
In addition, 258 (25.8%) organs showed minor developmental aberrations such as cystic persistent mesonephric tubules (8.9%), appendix epididymis (14.7%) and cystic remnants of mullerian duct (2.2%).
