In the epididymis, epithelial cells work in a concerted manner to create a luminal environment for sperm maturation, transport, and storage. However, the cell functions may be affected by anthropogenic factors, causing negative impacts on male fertility. In our study, we describe the pattern of protein expression in the epithelium and luminal fluid from epididymis of Oligoryzomys nigripes, a South American sigm...
Arsenic impairs male reproductive functions. However, it is not clear whether different arsenic compounds similarly affect fertility. In this study, we compared the impact of sodium arsenite and arsenate on sperm quality and fertility. After 56 d exposure, male Wistar rats were mated and pregnant females were evaluated by fertility indexes. Clearly, exposure to 10 mg/L arsenite reduced daily sperm production vi...
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; O Brasil está entre os países com biomas mais diversos e biologicamente mais ricos. A Mata Atlântica é um hotspot global de biodiversidade e o segundo maior bioma brasileiro em diversidade de espécies de mamíferos, no qual 30% deles são endêmicos. A presença de roedores na mata é de extrema importância, uma vez que influenciam a dinâmica das florestas...
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; Brazilian ecosystems, such as the Atlantic Forest, have suffered from the destruction and environmental contamination mainly when they involve the presence of substances that act as endocrine disruptors. Knowledge of reproductive aspects of wild rodents is important for environmental monitoring, as genital organs, as the epididymis, are indicators of ...
