Nonobstructive azoospermia: a spectrum, not a single disease

In the article by Majzoub et  al. (1), the authors set out to create a predictive model for successful testicular sperm aspiration (TESA) in men with nonobstructive azoospermia (NOA). The authors used retrospective data from 297 men diagnosed with NOA who underwent TESA followed by microdissection testicular sperm extraction ( mTESE) if sperm was not identified on TESA. Overall TESA, was successful in finding sperm in 23.6% of men, which is similar to a meta-analysis comparing TESA to mTESE (TESA was successful in 28% of NOA men) (2).
