Purpose: Non-obstructive azoospermily (NOA) in infertile men to investigate the factors affecting the success of sperm finding with microdisection testicular sperm extraction (micro TESE). The data of a total of 75 patients under micro-TESE surgery due to NOA between January 2015 and February 2020 were reverse assessed. Physical examination of all patients, hormone values, testicular volumes and histopathological findings were recorded. Results: 41 out of seventy-five men (54.7 percent) were micro TESE positive, while 34 out of them (45.3 percent) were micro TESE negative. The average age of patients with micro-TESE positive was 32,5 (22-54) years, and the negative was 32 (26-48) years (p = 0,515). TESE positive and negative patients have not found any significant differences when compared with infertility time, right and left testicular volume (respectively; p =0,595, p =0,060 and p =0,113). In the micro TESE positive group, the level of median follicle stimulating hormone (FSH) was 6.25 (0.30-47.30) IU/L while in the micro TESE negative group it was 9.10 (0.80-66.40) IU/L and was statistically meaningful (p = 0.048). In patients with hypospermatogenesis, the rate of obtaining sperm was higher than in patients with maturation arthritis, Sertoli cell only and fibrosis (respectively; 93.1, 37.9, 27.3, 16.7). The result: FSH levels and testicular histopathology appear to be important predictive factors affecting the success of sperm finding in micro TESE.
