Abstract

Anatomical investigations were made on the sex organs obtained from 15 bulls. The findings obtained were as follows : 1. Among the testis, epididymis and tunica vaginalis, fine fibrous adhesions were observed in 11 cases; most of the adhesions were bilateral. 2. The differences in the anatomical positions of attachment of the ampulla to the seminal vesicle were classified into four types : dorsal (5 cases), ventral (1), intermediate (7) and mixed types (2). 3. The reciprocal differences between sizes of the right testis, epididymis, seminal vesicle and bulbo-urethral gland on the one hand and those of the left on the other were statistically insignificant, respectively. Likewise there was no correlation between the ages of the animals and weights of these organs. The writer's gratitude is first to be expressed to Professor T. ISHIKAWA, Chief of the Department of Obstetrics, for his kind guidance and reviewing of the paper. Further, indebtedness is acknowledged to the Inspectors of the Sapporo and Tsukisappu Abattoirs for their great kindness and to the members of each AI center and the farm who kindly sent clinical data on the bulls used. Thanks is also offered to Assistant Professor K. KAWATA and the members of the Department for their kind advice and assistance.
