(A–F) Different seminiferous tubular histology patterns from TESE samples. Tissues were fixed in Bouin's solution and haematoxylin.eosin stained (A–E) and PLAP antibody haematoxylin stained (F). (A) Seminiferous tubules showing intact spermatogenesis. (B) Seminiferous tubule showing arrest of spermatogenesis at the level of primary pachytene spermatocytes. (C) Seminiferous tubules showing only Sertoli cells (SCO). (D) Different patterns of SCO including hyperplastic Sertoli cells (arrows), and thickening of lamina propria (arrowhead). (E) Total atrophy of seminiferous epithelium leaving only thickened lamina propria (tubular shadows). (F) Seminiferous tubule showing preinvasive testicular intraepithelial neoplasia indicated by the expression of Placental Like Alkaline Phosphatase (PLAP) of atypical germ cells (arrows) next to seminiferous tubule showing intact spermatogenesis.
