1. Reproductive toxicity of neem seeds (Azadirachta indica) in male quail (Coturnix coturnix japonica)
RESUMO: Considerando que o neem (Azadirachta indica A. Juss.) causa efeitos deletérios na fertilidade, objetivou-se avaliar o efeito da alimentação com sementes de neem sobre a qualidade seminal, parâmetros biométricos e morfometria testicular com codornas (Coturnix coturnix japonica Linnaeus, 1758) com 90 dias de idade, como modelo experimental. Após

2. Aspectos da biologia reprodutiva de Boa constrictor constrictor: um estudo histológico dos testículos nos períodos reprodutivos de quiescência e máxima atividade
RESUMO As serpentes pertencem ao segundo maior grupo dentro dos répteis, podendo apresentar sazonalidade quanto à espermatogênese, com produção descontínua ou contínua. O presente trabalho tem como objetivo caracterizar aspectos da biologia reprodutiva de Boa constrictor constrictor com base nos achados histológicos dos testículos nos períodos de m

3. The Effect of Jatropha Curcas Seed Meal on Growth Performance and Internal Organs Development and Lesions in Broiler Chickens
ABSTRACT The meal of Jatropha curcas (JCM) seed is a by-product of the biofuel industry and may potentially to be used as animal feed. However, its toxicity has prevented its utilization in animal nutrition mainly due to its high concentration of phorbol esters. This study was conducted to evaluate the effects of the dietary inclusion of JCM on the growth pe

4. Angiotensin-converting enzyme inhibitors of Bothrops jararaca snake venom affect the structure of mice seminiferous epithelium
Background Considering the similarity between the testis-specific isoform of angiotensin-converting enzyme and the C-terminal catalytic domain of somatic ACE as well as the structural and functional variability of its natural inhibitors, known as bradykinin-potentiating peptides (BPPs), the effects of different synthetic peptides, BPP-10c (

5. Metabolic and Testicular Effects of the Long-Term Administration of Different High-Fat Diets in Adult Rats
ABSTRACT Purpose: To evaluate the effects of different high-fat diets on body mass, carbohydrate metabolism and testicular morphology in rats seven months old.
Materials and Methods: Male Wistar rats were divided into four groups: SC (standard chow), HF-S (high fat diet rich in saturated fatt

6. Annual male reproductive activity and stages of the seminiferous epithelium cycle of the large fruit-eating Artibeus lituratus (Chiroptera: Phyllostomidae)
The large fruit-eating phyllostomid bat, Artibeus lituratus (Olfers, 1818), forearm 69-75 mm, body mass 66-82 g, has a diversified geographic distribution in the Neotropical region. Therefore it is subjected to different climatic conditions that affect its reproduction, leading to different reproductive strategies such as continuous reproduction, seasonal mo

7. Testicular Histomorphometric Evaluation of Zebu Bull Breeds
The objective of this study was to evaluate the quantitative histology and testicular biometrics in zebu bulls of different breeds. Testicular fragments of Nelore (n=10), Polled Nelore (n=6), Gir (n=5), Guzerat (n=5) and Tabapuã bulls (n=5) were used. The fragments were perfusion-fixed in Karnovsky solution, embedded in glycol methacrylate and stained with

8. Pneumoperitoneum induces morphological alterations in the rat testicle
PURPOSE:To investigate the seminiferous tubule histological morphology after an 8 mmHg pneumoperitoneum in the rat model. METHODS: Fourteen rats were divided into two groups: a Sham group submitted to anesthesia and a pneumoperitoneum (Pp) group submitted to abdominal insufflation at 8 mmHg during three hours, followed by desuflation. All rats were killed af

10. Morphophunctional assessments of testis in adult coatis (Nasua nasua Linnaeus, 1766) / Avaliação morfofuncional do testículo de quatis (Nasua nasua, Linnaeus, 1766) adultos
The study of the testicular morphophysiology in wild animals has been increased in the last years, seeking the development of protocols in assisted reproduction, due the constants threats on the fauna with the crescent human development. On the other hand, some few species, like the procyonids coati (Nasua nasua), present great adaptability to adverse condit

11. Testicular morphology and morphometry in mice chronically exposed to arsenic / Morfologia e morfometria testicular de camundongos adultos submetidos à exposição crônica ao arsenato
There is an increasing concern about the potentially harmful effects of several environmental pollutants, as for instance, the inorganic arsenic, one of the main pollutants of the water worldwide. The intoxication by arsenic can be acute or chronic, and lead to a variety of pathologies and impairment of male reproductive system. This work aimed to investigat

12. Morfometria testicular em ratos wistar adultos tratados com paracetamol (acetaminofeno) / Testis morphometry in adult Wistar rats treated with acetaminophen
Acetaminophen is non-prescrition analgesic and antipyretic considered safe and well tolerated in therapeutics doses, but it might cause hepatic and extrahepatic damage in animal and human models exposed to high doses. The chronic use of paracetamol in supratherapeutics doses has been implied in testicular lesions and sexual behavior alterations in animal mod
