Histological description of the reproductive system of male and female hatchlings of the Magdalena river turtle (Podocnemis lewyana)

ABSTRACT: In this study we described the macroscopic and microscopic histology of the reproductive system of male and female Podocnemis lewyana neonates (3.5 months old). We found macroscopic differences in the morphology of the gonads between the sexes, with ovaries being twice as long as testes, a...

description ABSTRACT: In this study we described the macroscopic and microscopic histology of the reproductive system of male and female Podocnemis lewyana neonates (3.5 months old). We found macroscopic differences in the morphology of the gonads between the sexes, with ovaries being twice as long as testes, and testes being twice as wide as ovaries. Microscopically, we identified several immature elements, such as the lack of a muscle layer in the oviduct of females, and simple epithelia instead of pseudostratified epithelia in the oviduct and epididymis described in reptile adults. We also found a black pigment observed macroscopically in the mesovarium, and macroscopically and histologically in the epididymis. This pigment is consistent with the center of melano-macrophages described in other vertebrates. Finally we described a supporting mesenchymal structure, the appendage of the oviduct, which was much longer than what has been described in other Podocnemis species.

Se hallaron diferencias macroscópicas en las gónadas, esto es, el ovario fue el doble de largo relativo al testículo, pero el testículo fue el doble de ancho relativo al ovario. Microscópicamente se identificaron varios elementos inmaduros tales como la ausencia de una capa muscular reportada en el oviducto de hembras de reptiles adultas, y epitelios simples en lugar de epitelios pseudoestratificados en oviducto y epidídimo en reptiles adultos. También se describe un pigmento negro observado macroscópicamente en el mesoovario de las hembras, y macroscópica e histológicamente en el epidídimo de los machos. Este pigmento es compatible con los centros de melanomacrófagos reportados en otros vertebrados. Finalmente, se describe también una estructura mesenquimatosa de soporte que identificamos como el apéndice del oviducto, la cual fue mucho más larga que las descritas en otras especies de Podocnemis.COL0006779COL00929649application/pdfengUniversidad Nacional de Colombia, Facultad de Ciencias, Departamento de BiologíaGrupo de Investigación en Agrociencias Biodiversidad y Territorio GAMMAGrupo de Investigación en Patobiología - QUIRÓNBogotá, Colombiainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARTArtículo de investigaciónhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/2.5/co/http://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-sa/4.0/Histological description of the reproductive system of male and female hatchlings of the Magdalena river turtle (Podocnemis lewyana)Descripción histológica del sistema reproductivo de machos y hembras de la tortuga del Río Magdalena (Podocnemis lewyana)OvaryOvarioTestisTestículoEpididymisEpididimoHistologyHistologíaOviductsOviductosPigmentsPigmentoshttp://aims.fao.org/aos/agrovoc/c_10635http://aims.fao.org/aos/agrovoc/c_330909http://aims.fao.org/aos/agrovoc/c_5461http://aims.fao.org/aos/agrovoc/c_5875Acta Biolo.
