ObjectiveThe aim of this study was to analyze the results of microsurgical testicular sperm extraction (micro-TESE) and investigate the potential factors that may affect the successful sperm retrieval and timing of micro-TESE.MethodsA total of 56 patients with nonobstructive azoospermia (NOA) who underwent micro-TESE procedure between January 2017 and December 2019 were retrospectively analyzed. The patient age, marriage duration, infertility duration, smoking, chronic illness, varicocele status, previous scrotal surgeries, and the presence of genetic disease were noted by an urologist for all patients.ResultsThe mean age of patients was 33.28±4.4 (22-44) years. Our total sperm-retrieval rate was 55.4% (n:31). Sixteen (28.6%) pregnancies were achieved and 15 (26.8%) healthy live births could be managed. Only the marriage duration (p=0.016) and infertility duration (p=0.015) were detected to be the significant factors to manage successful sperm retrieval. Men with NOA younger than 35.2 years and having a female partner younger than 36.9 years seemed to have the best chance to have a living healthy baby.ConclusionsThe fertility decreased by both male and female age and for men with NOA. The early visit to doctor seemed to have positive effect.
