| Purpose: The purpose of our study was to assess the usefulness of ultrasounddetermined
testicular volume in the evaluation of the infertile men with azoospermia.
Materials and Methods: A computerized search from October 2005 to June 2010
generated a list of 45 infertile men with azoospermia (mean age, 34 years; age range,
26-44 years) who underwent both scrotal ultrasound and testis biopsy. Ultrasounddetermined
testicular volumes were compared between infertile men with obstructive
azoospermia and those with non-obstructive azoospermia.
Results: Testicular volume for obstructive azoospermia ranged from 6.4 ml to 26.9
ml, with a median volume of 14.0 ml. This volume was significantly larger than that of
those with non-obstructive azoospermia, which ranged from 1.0 ml to 12.8 ml, with a
median volume of 6.1 ml (p < 0.001). The area under the ROC curve for distinguishing
non-obstructive azoospermia from obstructive azoospermia using testicular volume
was 0.91. A cutoff value of less than or equal to 11.4 ml could distinguish non-obstructive
azoospermia from obstructive azoospermia, with a sensitivity of 94.1% (95% CI;
71.3-99.9%) and a specificity of 73.3% (95% CI; 54.1-87.7%).
Conclusion: Ultrasound-determined testicular volume can be helpful in the differentiation
of obstructive azoospermia from non-obstructive azoospermia. |
