Non-obstructive azoospermia (NOA) is the diagnosis of one percent of all men and 10% of men complaining about infertility (1, 2). All NOA patients should be evaluated with complete history and physical examination, with genetic testing (karyotype analysis and Y chromosome microdeletion testing) being offered and performed, which will identify the causes of NOA in up to 17% of men (3, 4). Hormonal profile is also important as up to 47% of men that have impaired spermatogenesis with NOA were found to have hypogonadism (4,5).
