Diagnostic yield of OCT3/4 reflex testing in testicular biopsy

Histopathology, Volume 89, Issue 1, Page 136-143, July 2026.
GCNIS detection frequency was 48/3353 (1.4%) testicular biopsies from 42/1870 (2.2%) men who underwent testicular biopsy with or without testicular sperm extraction (TESE). OCT3/4 was particularly helpful for detecting interstitial seminoma, GCNIS coexisting with mature spermatogenesis, and focal GCNIS.
