Background. Nonobstructive azoospermia (NOA) is a frequent cause of male infertility, and microsurgical testicular sperm extraction (micro-TESE) is an effective technique for sperm retrieval in NOA cases. However, the predictive factors for successful sperm retrieval and the outcomes of micro-TESE in NOA patients are not fully understood. Methods. In this retrospective study, we evaluated the predictive value of preoperative data and outcomes of micro-TESE in 172 men with NOA who underwent the procedure between April 2012 and February 2021. Patients' age, medical history, testicular size, hormonal profile, testicular histology, and sperm retrieval were recorded. Results. 172 cases of micro-TESE were performed (99 unilateral and 73 bilateral) and testicular sperm retrieval rate (SRR) was 72.7%. There was no statistical difference in age, testicular size, and hormonal profiles between positive SRR and negative SRR groups. Clinical varicocele and previous orchitis did not significantly affect the result of micro-TESE. Y chromosome microdeletions were detected in seven patients. On histological examination, hypospermatogenesis was found in 39% of patients who underwent testicular biopsy. SRR was higher in patients with hypospermatogenesis than in other groups. Conclusions. Testicular microdissection is an effective and safe procedure for nonobstructive azoospermia patients, regardless of the different etiologies and preoperative data. Age, testicular size, and hormonal levels did not predict the success of micro-TESE. The presence of hypospermatogenesis was associated with a higher SRR. Clinical varicocele and previous orchitis were not significantly associated with the outcome of micro-TESE.

Abstract

Background. Nonobstructive azoospermia (NOA) is a frequent cause of male infertility, and microsurgical testicular sperm extraction (micro-TESE) is an effective technique for sperm retrieval in NOA cases. However, the predictive factors for successful sperm retrieval and the outcomes of micro-TESE in NOA patients are not fully understood. Methods. In this retrospective study, we evaluated the predictive value of preoperative data and outcomes of micro-TESE in 172 men with NOA who underwent the procedure between April 2012 and February 2021. Patients' age, medical history, testicular size, hormonal profile, testicular histology, and sperm retrieval were recorded. Results. 172 cases of micro-TESE were performed (99 unilateral and 73 bilateral) and testicular sperm retrieval rate (SRR) was 72.7%. There was no statistical difference in age, testicular size, and hormonal profiles between positive SRR and negative SRR groups. Clinical varicocele and previous orchitis did not significantly affect the result of micro-TESE. Y chromosome microdeletions were detected in seven patients. On histological examination, hypospermatogenesis was found in 39% of patients who underwent testicular biopsy. SRR was higher in patients with hypospermatogenesis than in other groups. Conclusions. Testicular microdissection is an effective and safe procedure for nonobstructive azoospermia patients, regardless of the different etiologies and preoperative data. Age, testicular size, and hormonal levels did not predict the success of micro-TESE. The presence of hypospermatogenesis was associated with a higher SRR. Clinical varicocele and previous orchitis were not significantly associated with the outcome of micro-TESE.
