title: Seminal vesicle parameters at 10-year intervals measured by transrectal ultrasonography.
abstract: The volume, maximum horizontal area, maximum length, maximum width and depth of the seminal vesicles were measured by transrectal ultrasonography in 76 subjects without seminal vesicle disorders, divided into 7 groups at 10-year intervals. The average of each parameter in each group was presented. The volume and maximum horizontal area began to decrease after the age of 60 years. No statistically significant difference among subject ages was observed for the other 3 parameters. A correlation 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.
