Abstract
Purpose: Testicular volume is one of the important indices that represent the reproductive ability of adult males. In previous studies, however, testicular volume was measured by manual palpation or orchidometer, resulting in inaccuracy or subjectivity. Accordingly, the need for accurate data on the size of the testes is increasing, and we conducted testicular volume measurements by using scrotal ultrasonography. We investigated the relationship between testicular volume and body weight, height, and body mass index (BMI). Materials and Methods: The testicular volumes of 1,002 young adult Korean men were measured for length, width, and thickness with ultrasonography, and data on BMI were collected conventionally. The correlation between testicular volume and BMI was analyzed with one-way ANOVA and Student's t-test. Results: The mean age of the young men was 23.02±2.53 years. The mean testicular volume was 18.09±3.79 cc on the left and 18.26±3.21 cc on the right. Testicular volume was directly proportional to body weight, height, and body mass index. Conclusions: The testicular volume of Korean young adult men was about 18.17 cc. Testicular volume has a weak direct correlation with body weight, height, and body mass index.
