Fig. 1From: Azoospermia and reciprocal translocations: should whole-exome sequencing be recommended?Immunohistochemical assessment of seminiferous tubule expression of TMPRSS9 (A: control; B: patient 2) and DNMT3B (C: control; D: patient 2) in the testes. A and C: normal spermatogenesis, showing normal expression of TMPRSS9 and DNMT3B. B and D: spermatogenesis arrested at the spermatocyte stage, with no expression of TMPRSS9 or DNMT3B. Staining: the antigen-antibody complex was visualized with the DAB detection system, and slides were counterstained with haematoxylinBack to article page
