![]() ![]() There is however a paucity of data for testicular volume measurements by ultrasound in Nigeria, thus necessitating the need for accurate data on the volume of the testes in Nigerian men. The diagnosis of androgenic and testicular diseases depends on the ability to elicit minimal changes in the testicular volume. Testicular volume is one of the important indices that depict the reproductive capability of a man. The results of this study show that ultrasonography and the formula L × W × H × 0.71 are the most accurate method for the calculation of the testicular volume. The smallest mean difference from the actual testicular volume was observed with the formula L × W × H × 0.71, which underestimated the actual volume by 0.4 ml (3.9%).Conclusion A strong correlation was found between the actual testicular volume and the volume calculated by the three-ultrasound formulas (r = 0.853–0.871, p = 0.0001). The actual testicular volume was determined by water displacement of the testis.ResultsThe mean actual testicular volume was 10.6 ± 3.5 ml. The ultrasound measurements of the testicular volume were calculated using the following three formulas: (a) length (L) × width (W) × height (H) × 0.52 (b) L × W2 × 0.52 and (c) L × W × H × 0.71. To determine the accuracy of various ultrasound formulas for measuring the testicular volume in humans by comparing the resultant measurements with the actual testicular volume.Subjects and methodsThe testicular volume of 121 testes from 62 patients with prostate cancer (mean age 72.7 ± 9.4) was measured using ultrasonography before therapeutic bilateral orchidectomy. The results were expressed as percentages and tests of significance were done using the chi-square and Student's t-test. All the subjects had their testes examined using a high frequency (7.5 mHz) linear transducer of an ultrasound scanner. The relevant clinical history of each patient was extracted from their case notes. The subjects comprised of 136 patients with diagnosis of male infertility, as well as 100 healthy individuals as control. Patients and methods: The study examined 236 subjects over a period of one year. Objective: To evaluate the relationship between testicular volume and function using scrotal ultrasound scan in black West African men. Neither the critical minimum testicular volume that guarantees adequate function, nor the optimal testicular volume that indicates peak testicular function are also known. ![]() However, racial variations in testicular volume do exist. 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.īackground: While the semen analysis appears to be the cornerstone in the evaluation of testicular function, the testicular volume has long been associated with testicular function. 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. 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. Results: The subjects' age ranged from 19 to 29 years with a mean of 23.48 ± 2.26 yrs. Ultrasound measurement of the height, length, and width of both testes were done and used to calculate the volumes using the three formulae. Height and body weight were measured while the BMI and BSA were calculated. Methodology: One hundred twenty-five adult male subjects comprising staff and students of a University Teaching Hospital were recruited into the study. ![]() 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. Ultrasonography is an important and accurate radiological method for measurement of testicular volume. Background: Measurement of testicular volume is one of the ways of assessing testicular function. ![]()
