OBJECTIVE: There is no clear consensus on which patients and how many of microscopic testicular sperm extraction (mTESE) procedures will be successful. In this study, we aimed to evaluate the sperm retrieval rates and factors affecting these rates in men who underwent repeat mTESEs. MATERIAL AND METHODS: A total of 346 patients who underwent mTESE for sperm retrieval were included in the study. Patients were divided into groups according to the number of mTESE operations. Patients' karyotype, follicle-stimulating hormone (FSH) and testosterone levels, varicocele presence, and testis volumes were recorded from patient files. The sperm retrieval rates were compared between groups, and predicting factors for successful sperm retrieval were evaluated. RESULTS: Microscopic TESE was applied for the first time in 244 patients, 1-2 times in 73 patients, and 3-4 times in 29 patients. There was a significant difference between groups in preoperative FSH values and postoperative testicular histopathology (p=0.004 and p<0.001). The sperm retrieval rate in the group of patients who had not undergone previous TESE was higher than the group of patients that had undergone TESE for 1-2 times and 3-4 times (p=0.028). In addition, testicular volume, histology, karyotype, and Y-chromosome microdeletion were predicting factors for successful sperm retrieval (p=0.011, p=0.039, p=0.002, and p<0.001, respectively). CONCLUSION: Our results confirm the necessity for repeat mTESE operations to be performed by experienced surgeons in reference centers to optimize the chance of reduced sperm retrieval rates with recurrent biopsies.
