Testicular Biopsy in Azoospermia and Severe Oligozoospermia [PDF]
Archives of Andrology, 1984 The continued experience of testicular biopsy application in 861 cases of azoospermia and 152 cases of severe oligospermia is reported adding to the previously published cases of 1075 patients with azoospermia. The most common finding in the whole series was that of normal testis denoting obstruction (48%), while among cases of functional azoospermia ...

Diagnostic yield of OCT3/4 reflex testing in testicular biopsy
Histopathology, EarlyView.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.
