In this study, we decided to investigate the normal size and normogram of testicular volume in children in patients referred to the Imaging Center of Imam Khomeini Hospital in Tehran during the years 2019 to 2021.
Material and Methods:
This study was a cross-sectional study. The study population was all boys aged 0 to 15. Using ultrasound, the volume of the testis was calculated using the formula (length * width * height of a fixed number 0.71). After collection, the data were entered into SPSS version 20 and statistical analysis was performed using statistical tests.
825 boys aged 0 to 15 years in 15 groups of 55 people were included in the study. The mean volume of the left testicle was 2.14 ± 2.02 cc, the mean volume of the right testicle was 1.93 ± 1.74 cc and the mean total volume of both testes was
3.42 ± 6.01 cc. There was a statistically significant difference between the mean BMI, height and weight between the groups (p <0.05). Also, according to the results, a statistically significant difference was found between the mean volume of right testicle, left testicular volume and total testicular volume in the studied groups. There was a statistically significant difference between the mean total testicular volume in terms of BMI, height and weight; So that with the increase of the mentioned variables, the total volume of the testis in the patients increased.
It can be concluded that three criteria of weight, BMI and height, affect the testicular volume in boys 0-15 years and increasing each of these variables, testicular volume also increases significantly.
