Background: Pediatric testicular volume is an important index in determining the start of puberty, its progress, and/or any subsequent disorder of puberty. It is also important in detecting and monitoring local testicular pathologies. This study is aimed at obtaining reference values for testicular volume measured by ultrasound in normal pediatric age group 0-15 years. Materials and Methods: This cross-sectional study was conducted at the Radiology Department of Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. Boys numbering 450 without any evidence of testicular pathology were recruited for this study. The testicular volume was measured by ultrasound (Aloka SSD 3500) utilizing the testicular length, width, and thickness of the ultrasound images. All measurements were analyzed using Statistical Package for Social Sciences (SPSS 17). A P ≤ 0.05 was considered statistically significant. Results: The testicular volume shows no significant increase before the age of 9 years with an average volume of 0.74 ml and then increased to 1.1 ml at 9 years. Afterward, it shows marked increase in volume to reach a value of 8.99 ml at 15 years. Strong correlations were established between the right and left testicular parameters, except for the anteroposterior diameter. However, no statistically significant difference was observed between them, except for length (P = 0.000). Conclusion: The study provides contemporary reference values for testicular volume of the pediatric age group.
