Evidence of the antigenicity of testis and semen was first presented at the end of the last century. Landsteiner (1899), Metchnikoff (1900), and Metalnikoff (1900) demonstrated the induction of a spermotoxic antibody in animals sensitized with testicular homogenate or semen; this antibody was capable of immobilizing sperm cells. The earliest manifestation of homologous type of antisperm sensitization (Kennedy, 1924) was the immobilization of spermatozoa, and in some cases atrophy of germinal epithelium, following repeated injection of testicular homogenate or epidydimal sperm. Ryoo and Kim (1982) reported that spermatogenesis was adversely affected with degeneration and sloughing of germinal cells of the seminiferous tubules in the mice which were immunized with testis homogenate plus complete Freund's adjuvant. The purpose of this study was to observe the effect of antitesticular rabbit serum produced against rat testis on spermatogenesis in rat. The results were as follows: 1.Theseminiferous tubules showed mild to moderate impairment of spermatogenesis such as degeneration and exfoliation of germinal epithelium in all experimental groups. Intraluminal spermatozoa of seminiferous tubules were decreased in number. Interspaces of seminiferous tubules were wider than normal and were infiltrated with mononuclear cells with some hemorrhage. 2. Intraluminal spermatozoa of the epididymides were markedly decreased in number but immature sperm cells were observed much more often than in normal control group.

In urinary tuberculosis, during recent years, there has been remarkable progress in treatment new aspects have been reported, which raise problems in diagnosis. There is an increase of silent forms, forms with rapid destructive development even under treatment and forms masked by association with other disease. We made a clinical study on 9 cases of renal tuberculosis which showed atypical symptoms, radiologic findings, cystoscopic findings and laboratory findings.

We experienced one case of epidermoid cyst. This tumor occurs usually in early adult life. So simple excision and testicular preservation are desirable when frozen section reveals the presence of an unequivocally benign lesion.
