This study proposes a testicular sperm extraction technique that was inspired by testicular fine‐needle aspiration. Here, we have described the technique of open testicular mapping (OTEM) and evaluated the successful sperm recovery in 92 patients with nonobstructive azoospermia (NOA). All patients underwent an OTEM biopsy. Patients were divided into two groups; group I included men with spermatozoa recovered and group 0 included men without spermatozoa recovered. Age, follicle‐stimulating hormone (FSH) level and testicular volume were compared between the groups. In 50 of 92 men (54%), viable spermatozoa were found after OTEM. No differences were noted in age, FSH level or testicular volume. Using OTEM, it was possible to retrieve spermatozoa in 54% of the NOA men.
