Resumo: The aim of this work was to study the testicular morphometry of captivity-bred adult bullfrogs. Fifteen young adult male were studied, in the rainy season and a lengthy photoperiod. The GSI was established at 0.15%. The nuclear diameter of germinative and Leydig cells, the nucleolus diameter of Sertoli cells and the area of cysts and tubules were determined and the mean number of ISPC, IISPC and SPT per cyst and the mean number of cysts per tubule was estimated. The nucleoplasmatic proportion of the nucleus of the Leydig cell was 76.22%, indicating less cytoplasmic activity. Eight generations of spermatogonia were found. The spermatogenesis efficiency in meiosis and in mitosis was 63 and 49%, respectively. The spermatogenesis of bullfrog fited in the pattern of other captivity Anurans, with differences as the morphology of Sertoli and Leydig cells nuclei.

Existem muitos pontos a serem esclarecidos sobre a morfometria testicular desta espécie, que objetivamos desvendar neste trabalho. Quinze machos adultos foram estudados, em período chuvoso e de fotoperíodo longo (dezembro, 2000). O IGS encontrado foi de 0.15%. O diâmetro nuclear das células germinativas e da célula de Leydig, o diâmetro nucleolar das células de Sertoli e a área dos cistos e túbulos foram determinados. O número médio de ISPC, IISPC e SPT por cisto e o número médio de cisto por túbulo foi estimado. A proporção nucleoplasmática do núcleo da célula de Leydig foi de 76.22%, indicando pouca atividade citoplasmática. Oito gerações de espermatogônia foram estimadas. A eficiência da espermatogênese na meiose e mitose foi de 63% e49%, respectivamente. A espermatogênese de rãtouro segue os padrões dos demais Anuros de cativeiro, apresentando diferenças nos núcleos das células de Sertoli e Leydig.Brazilian Archives of Biology and Technology2019-05-29T13:38:27Z2019-05-29T13:38:27Z2009-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1516-8913http://dx.doi.org/10.1590/S1516-89132009000600018http://www.locus.ufv.br/handle/123456789/25602engv. 52, n. 6, p. 1461- 1472, nov.- dec. 2009Carlos, JaquelineMatta, Sérgio Luis Pinto dainfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:44:20Zoai:locus.ufv.br:123456789/25602Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:44:20LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
