Successful testicular sperm extraction in infertile male with non-obstructive azoospermia presented with bilateral atrophic testis: A case report.

Approximately 50% of men with NOA have minimal sperm production within their dysfunctional testes. Studies shown poor correlations between testicular size and sperm retrieval rates. A 34 years old man with NOA and bilateral testicular atrophic had a successful sperm extraction using mTESE from his 2.1 cc right testicle. Lower testicular volumes significantly decrease sperm retrieval rate in mTESE. However, we described a successful mTESE in atrophic testis. Therefore, small testicular volume does not affect the successful rate of mTESE and should not be a contraindication.
