| Objetivou-se com esta pesquisa testar dois protocolos de eletroejaculação e estudar a motilidade espermática progressiva, vigor, concentração e alterações morfológicas dos espermatozóides de catetos adultos criados em cativeiro. Utilizaram-se seis machos com idade entre 10 e 18 anos. Os animais foram anestesiados com cloridrato de zolazepan e cloridrato de tiletamina e em seguida coletou-se o sêmen com auxílio de um eletroejaculador. O volume médio do ejaculado foi 3,11 + 0,9mL, a motilidade espermática progressiva foi 48,7 ± 31,5%, o vigor, 2,1 + 1,4 e a concentração espermática média, 87,0 + 53,1 x 10(6) sptz/mL. Concluiu-se com esta pesquisa que a utilização de três sessões de 15 estímulos de 12 volts foi suficiente para coleta de sêmen de catetos... |

| This study aimed at the qualitative and quantitative characterization of the different intertubular tissue components in adult male capybara. Testes of 15 adult capybaras from a commercial slaughterhouse of wild animals were used. The average percentage of Leydig cells was 32.95 ± 10.03 %, whereas in the other components of the intertubular space it was 14.95 ± 4.79 %, thus the whole intertubular space totalized 47.91 ± 11.48 %. The average weight of the testes were 32.83 ± 4.78g, while the animals' body weight were around 52.37 kg and the gonadosomatic and leydigosomatic indexes were 0.125 ± 0.02% and 0.0411 ± 0.0148% respectively. It was concluded that the leydigosomatic index of the capybaras was lower than the one observed in rats, as well as the... |

| The aim of this study was to evaluate the possible beneficial effects of Catuaba Cristal® (CC), an alcoholic drink made from wine and Erythroxylum catuaba Ar. Cam on testis. Wistar rats either received CC solution (n=8) or water (n=9). Results showed significant body weight reduction within the CC group, although, no weight changes were observed for liver, kidney, testis, epididymis, seminal vesicle and prostate. The volumetric proportion and volume of interstitial tissue and lymphatic space were reduced in the treated group. In the CC group, although the nuclear volume of Leydig cells (LC) decreased, the number of LC per testis increased. These results suggested that CC had no beneficial effect on spermatogenesis of Wistar rats. |
