Testicular histopathology as a predictor of a positive sperm retrieval in men with non-obstructive azoospermia

BJU International, 05/17/2012

The presence of tubules with spermatazoa on biospy is the best predictor of a positive surgical sperm retrieval in patients with non–obstructive azoospermia. The diagnostic biopsy is best coupled with an initial testicular sperm extraction (TESE) before starting the intracytoplasmic sperm injection (ICSI) cycle. Based on the findings of the histopathology specimen, patients may be offered a repeat TESE if more sperm is needed on the day of ovum pick–up and ICSI, or a redo TESE if the initial TESE was negative.
