To obtain the normative values of the testis volume of 0－14 years old Chinese boys by ultrasound measurement.We collected the testicular ultrasound data on 1607 Chinese boys with normal testes between January 2016 and June 2019. The boys were aged 0－14 years and divided into 14 age groups, with at least 100 cases in each group. We compared the mean, standard deviation and median of the testis volume among different age groups.The testis grew slowly in volume before 8 years old (0.372－0.678 ml), faster after 9 years old (1.040－4.600 ml), (1.040 ± 0.970) ml at 9－10 years, (1.876 ± 1.631) ml at 10－11 years, (2.831 ± 2.155) ml at 11－12 years, (3.640 ± 2.376) ml at 12－13 years, and (4.600 ± 3.559) ml at 13－14 years, larger in the 0－1 than in the 1－2 years group (［0.403 ± 0.130］ vs ［0.372 ± 0.110］ ml, P = 0.04), negatively correlated in age between the two groups.Ultrasonography is an effective method for the measurement of the testis volume, which can provide the normative values of the testis volume of the 0－14 years old Chinese boys and some evidence for clinical diagnosis and consultation. |
