Abnormal spermatogenesis in Pten −/− mice. a Hematoxylin and eosin staining of sections from Pten +/+ and Pten −/− testes at 7, 32 and 73 days old (scale bar is 100 µm). b Hematoxylin and eosin staining of epididymis sections from Pten +/+ and Pten −/− mice at 32, 61, and 93 days old. Massive lack of normal sperm was observed in the epididymis of Pten −/− mice (scale bar is 100 µm).
