Nonobstructive azoospermia (NOA) is a condition in which no sperm is found in the ejaculate due to failure of spermatogenesis. Studies have identified specific biomarkers in men with NOA; however, few markers, such as karyotype and Y chromosome microdeletion, have been successfully translated to the clinic (1).
