1. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr

2. Use of testicular tone and echogenicity in identifying boars with low sperm quality
RESUMO O estudo objetivou avaliar o uso de características testiculares para identificar reprodutores com baixa qualidade de morfologia espermática. A consistência (escore de 1 a 5), o tônus por tonometria (mm), a ecogenicidade e a heterogeneidade do parênquima testicular por ultrassonografia (pixel) foram avaliados em 402 machos suínos maduros (18,5 m

4. Protective Effect of Rosa Canina Extract Against Doxorubicin-induced Testicular Toxicity in Mice
Abstract The present study was aimed to investigate the in vivo effects of Rosa canina extract on doxorubicin-induced testicular toxicity in mice for the first time. Male NMRI mice were randomly divided into six treatment groups (10=per group) as follows: (I) vehicles, (II) doxorubicin alone (3 mg/kg, i.p. on days 7, 14 and 21), (III and IV): Rosa canina ext

6. (+)-Catechin and (-)-epigallocatechin gallate: are these promising antioxidant therapies for frozen goat semen?
RESUMO Objetivou-se avaliar o efeito de diferentes concentrações de (+)-catequina ou (-)-epigalocatequina galato (EGCG) sobre a congelabilidade do sêmen caprino. Poolsseminais foram processados (experimento 1: 0, 15, 25, 50, 75 ou 100µM de (+)-catequina; experimento 2: 0, 15, 25, 50, 75 ou 100µM de EGCG) e congelados. Após a descongelação, foram aval

7. Efeito do ômega 3 e da vitamina B12 no espermograma, na histomorfometria dos órgãos reprodutivos e nas temperaturas do corpo com termografia infravermelha em ratos Wistar
RESUMO Objetivou-se estudar o efeito do ômega 3 e da vitamina B12 no espermograma, na histomorfometria dos órgãos reprodutivos e na temperaturas do corpo com termografia infravermelha em ratos Wistar. Utilizaram-se 16 ratos, em quatro grupos (n=4), que receberam injeções diárias por 30 dias, sendo: grupo controle - solução salina; grupo ômega 3 - ó

8. Morphological and histological characterization of sexual segment of the kidney in Notomabuya frenata (Cope, 1862) and Aspronema dorsivittatum (Cope, 1862) (Squamata, Mabuyidae)
Abstract The kidneys in two viviparous species of Neotropical lizards, Notomabuya frenata and Aspronema dorsivittatum (Mabuyidae), were investigated by light and scanning electron microscopy in order to determine the presence of the sexual segment of the kidney (SSK) and to study its morphology. The individuals used in this study belong to the Herpetological

9. Biochemical and seminal parameters of lambs fed palm kernel cake under grazing system
ABSTRACT This study aimed to assess the effects of palm kernel cake on semen quality and biochemical parameters of Santa Inês lambs. A total of 40 animals with 24.10±2.72 kg body weight and five months old were assigned in a completely randomized design into four groups and 10 replicates. The animals were subjected to four levels of palm kernel cake (0, 15
