ABSTRACT
OBJECTIVE: To obtain the normative values of the testis volume of 0ï¼14 years old Chinese boys by ultrasound measurement. METHODS: We collected the testicular ultrasound data on 1607 Chinese boys with normal testes between January 2016 and June 2019. The boys were aged 0ï¼14 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. RESULTS: The testis grew slowly in volume before 8 years old (0.372ï¼0.678 ml), faster after 9 years old (1.040ï¼4.600 ml), (1.040 ± 0.970) ml at 9ï¼10 years, (1.876 ± 1.631) ml at 10ï¼11 years, (2.831 ± 2.155) ml at 11ï¼12 years, (3.640 ± 2.376) ml at 12ï¼13 years, and (4.600 ± 3.559) ml at 13ï¼14 years, larger in the 0ï¼1 than in the 1ï¼2 years group (ï¼»0.403 ± 0.130ï¼½ vs ï¼»0.372 ± 0.110ï¼½ ml, P = 0.04), negatively correlated in age between the two groups. CONCLUSIONS: Ultrasonography is an effective method for the measurement of the testis volume, which can provide the normative values of the testis volume of the 0ï¼14 years old Chinese boys and some evidence for clinical diagnosis and consultation.
