    Abstract:
    OBJECTIVE: To investigate the clinicaleffects of micro-dissection of testicular sperm extraction (micro-TESE) and its combination with intracytoplasmic sperm injection (ICSI) in the treatment of non-obstructive azoospermia (NOA). METHODS: We retrospectively analyzed the clinical data on 130 NOA patients treated between December 2015 and December 2017, including36 cases of idiopathic NOA, 22 cases of idiopathic NOA with small testis, 18 cases of Klinefelter syndrome, 46 cases of surgically treated cryptorchidism and 8 cases of AZFc microdeletion.All the patients underwent micro-TESE and 29 of them with sperm received micro-TESE + ICSI. We observed the changes in the postoperative serum T level, analyzed the influences of different types of NOA and testicular pathology on the sperm retrieval rate (SRR) and the outcomes of ICSI. RESULTS: All the micro-TESE operations were successfully completed. The SRR was significantly higher in those surgically treated for cryptorchidism (60.9%) than in the other NOA groups (P<0.05), withstatistically significant differencesnot among the latter groups (P>0.05) but among differenttypes of testicular pathology (P<0.05), the highest in the hypospermatogenesis group (100%), very low in those with Sertoli-cell-only syndrome (11.8%), and the lowest in the cases of spermatogenesis arrest (0). The serum T level was remarkably decreased at 1 and 6 months after operation (P<0.01), but markedly higher at 6 than at 1 month (P<0.01). Of the 52 patients with sperm retrieved at micro-TESE, 29 of their spouses received ICSI, resulting in 17 pregnancies, 6 live births, and 6 spontaneous abortions. CONCLUSIONS: Micro-TESE is an effective method for the treatment of NOA, and its combination with ICSI can help the NOA patients obtain their genetic offspring.
