Description

The testicular volume of 1782 testes in 891 subjects between 0 and 86 years old was measured using the Test Size (Resimed Co, Switzerland), a metrological equipment for testis. We also compared the testicular volume calculated from tomographic images by testicular ultrasonographic measurements in some of these subjects and the actual volume of the isolated testes from the same subjects. The testicular volume measured with Test Size gradually grew at the age of 0 to about 8 years, rapidly increased in percentage at the age of about 12 to 13 years and reached to a peak at about 18 to 19 years. Comparison between the actually measured volume of isolated testes and the testicular volume with Test Size resulted in an index of 0.608 while comparison between that and the ultrasonographically measured testicular volume resulted in an index of 1.098. Therefore, authentic testicular volume is calculable by means of this method.
