SEMINAL-VESICLE PARAMETERS AT 10-YEAR INTERVALS MEASURED BY TRANSRECTAL ULTRASONOGRAPHY

The volume, maximum horizontal area, maximum length, maximum width and depth of the seminal vesicles were measured by transrectal ultrasonog raphy in 76 subjects without seminal vesicle disorders, divided into 7 groups at 10-year intervals. The average of each parameter in each gr oup was presented. The volume and maximum horizontal area began to dec rease after the age of 60 years. No statistically significant differen ce among subject ages was observed for the other 3 parameters. A corre lation was observed between the volume and maximum horizontal area of the seminal vesicles. Our study confirmed that maximum horizontal area of the seminal vesicles may be substituted for the volume.
