Seminal vesicles were atrophied or not developed according to the lowering of the androgenic activities of the testis an I found tuberculous infection in them frequently. And it is well-known such conditions result in the disturbance of the sperm nutrition and the sperm passage which lead to the male sterility respectively. From these points, I have been, for the past seven years, observing the rentogenologic forms of semlnal vesicles about male sterility of 106 cases, and found out their morphological variations. On the classifications of seminal vesiculograms, there have been many reports, but could not be found that of seminal vesiculograms about male sterility. Then, it is intended to classify the forms of seminal vesicles of my cases as follows. 1. great main tubes with large laminated diverticula 2. great main tubes with or without small diverticula 3. simple main tubes with large laminated diverticula 4. simple main tubes with or without small diverticula 5. main tubes, dilated abnormally, demarcated poorly or irregularly, and no shaped seminal vesicles by means of the difficulties in injection of contrast medias into the vas deferens (stricture, obstruction or absence of it) The writer utilized vasopuncture of scrotal region and through the vas deferens injected Urografin and Urokolin-M into seminal vesicles. As table (2-16) shows, in seminal vesicles type No. 1 of the classification commanded a plurality (49.5%), Type No. 2 is the second (28.3%) and in Ampulla ductus deferentis, type No. 1 is first in number (60.6%) and type No. 2 next (19.2%). Seminal vesicles in male sterility are well-grown, and the angle of inclination of them have a tendency to be small (on an average 27.3 degree). Author's original classification of type No. 5 is 5.5%. But tuberculous findings in seminal vesicles are seen in few cases, on the contrary the abnormal dilatation of main tubes found frequently.
