Abstract
Background: Measurement of testicular volume is one of the ways of assessing testicular function. Ultrasonography is an important and accurate radiological method for measurement of testicular volume. Objective: This study was aimed at evaluating the relationship of ultrasound measured testicular volume using the three formulae with the subjects' height, body weight, body surface area (BSA), and body mass index (BMI) in adults. Methodology: One hundred twenty-five adult male subjects comprising staff and students of a University Teaching Hospital were recruited into the study. Height and body weight were measured while the BMI and BSA were calculated. Ultrasound measurement of the height, length, and width of both testes were done and used to calculate the volumes using the three formulae. Results: The subjects' age ranged from 19 to 29 years with a mean of 23.48 ± 2.26 yrs. The mean ultrasound measured volumes for the right and left testes were 15.38 ± 3.29 ml and 15.29 ± 3.89 ml using the prolate ellipsoid formula; 22.86 ± 5.43 ml and 23.54 ± 6.88 ml by the prolate spheroid formula; 21.20 ± 5.28 ml and 20.87 ± 5.35 ml by the Lambert formula, respectively. The calculated mean for height, body weight, BMI, and BSA were 174.64 ± 6.36 cm, 68.68 ± 8.25 kg, 22.48 ± 2.17 kg/m2, and 1.82 ± 0.13 m2, respectively. The right testes showed a negative correlation, while the left and combined testicular volumes showed a positive correlation with the subjects' height, body weight, BMI, and BSA for all the three formulae. Conclusion: The right testicular volume showed negative correlation, while the left and combined testicular volumes showed a positive correlation with the height, body weight, BSA, and BMI in Nigerian adults.
