TEX101 and Azoospermia: All azoospermia cases diagnosed as NOA by ECM1 ≥ 2.3 μg/mL and TEX101 ≥ 0.9 ng/mL will thus be correct (32 patients), while 19% of patients diagnosed as OA based on ECM1 < 2.3 μg/mL and TEX101 < 0.9 ng/mL (eight patients in the current set) will be actually NOA (false negatives).
