Rate of testicular histology failure in predicting successful testicular sperm extraction
BackgroundThe management of Non-Obstructive (NOA) Azoospermia or Obstructive Azoospermia (OA) patients relies on testicular sperm extraction (TESE) followed by intracytoplasmic sperm injection (ICSI).In NOA patients the sperm recovery is successful in only 50% of cases and therefore the ability to predict those patients with a high probability of a
