Comparison of Efficacy of Open Testicular Biopsy and SpermExtraction (TESE) versus Testicular Sperm Aspiration (TESA) interms of Sperm Retrieval Rate (SRR) in patients of Non-ObstructiveAzoospermia (NOA)
Abstract
Objective: Objective of our study was to compare the yield of TESE versus TESA in terms of SRR in patients of NOA.Methods
This randomized clinical trial was conducted in Department of Urology, Mayo Hospital Lahore. Patients diagnosed with NOA were selected and written informed consent was obtained. Baseline demographic and clinical information was recorded. Patients were then randomly allocated to two groups. Group A patients underwent TESE while TESA was performed in Group B patients. SRR of both groups were assessed and compared.Results
Mean age of patients undergoing TESE and TESA was 29.73 ± 4.57 and 27.73 ± 4.88 years respectively (p = 0.766). Mean BMI of patients in undergoing TESE was 21.93 ± 1.24 kg/m2 while mean BMI of patients undergoing TESA was 22.46 ± 1.49 kg/m2 (p = 0.783). SRR of TESE was 66.6% while SRR of TESA was 40.0% (p = 0.038).Conclusion
TESE was found to be more effective sperm retrieval technique in patients of NOA.Keywords:
