Immunohistochemical analysis results (×400 magnification) of cAMP responsive element modulator protein in human testicular sections with normal spermatogenesis (A), spermatid maturation arrest (B), and hypospermatogenesis (C). Positive cAMP responsive element modulator immunoreactivity was visualized as eosinophilic nuclear staining as indicated by the arrows.
