On 596 healthy boys and adolescents from 4 to 17 years of age measurements of the length and the width of the left testis as well as of the thickness of scrotal skin were carried out by means of a caliper, and the testis volume was secondarily calculated. Age specific mean values (means) and their +/- 2 s-limits are listed. Nonlinear s-shaped regression lines of the three main parameters clearly underline that the greatest increase is to be found in the length of testis. Consequently, as an indicator for gonadal developmental disturbances instead of testis volume measuring of testis length is recommended for routine in the physical examination of inpatients and outpatients as well as for the screening of schoolboys and male teenagers.
对4至17岁的596名健康男孩和青少年，用卡尺测量了左侧睾丸的长度和宽度以及阴囊皮肤的厚度，并据此计算出睾丸体积。列出了各年龄组的均值及其±2标准差范围。三个主要参数的非线性S形回归线清楚地表明，睾丸长度的增长最为显著。因此，对于住院和门诊患者的体格检查以及对男学生和青少年男性的筛查，建议常规测量睾丸长度，而非睾丸体积，以此作为性腺发育障碍的指标。
