Histological sections of embryonic Pogona vitticeps urogenital systems stained with haematoxylin and eosin (H & E). (a) Bipotential gonads with developing cortex and medullary regions during migration towards the anterior mesonephros. (b) Ovotestes from an embryo incubated at 36 °C undergoing sex reversal showing a proliferating cortex with oogonia, a medulla with numerous rudimentary seminiferous tubules. (c) Differentiated ovary with a reducing medulla, cortex proliferating with oogonia. (d) Differentiated testes with a reducing cortex, and medulla with developing seminiferous tubules. B. P = bipotential gonad, Mes. = mesonephros, C = cortex, M = medulla, black arrows = seminiferous tubules.
