Abstract

Seminal plasma (SP) contributes to sperm physiology and metabolism, prevents premature capacitation, and protects sperm against oxidative stress. In order to evaluate the impact of heat stress in the semen of tropically adapted Brangus breed and in their seminal plasma proteome, we studied the ...

Abstract

Although season has been shown to affect bull sperm quality and fertility in some studies, the effect of season on seminal plasma proteins has not been examined. In the present study, seminal plasma proteins were analysed by Fast Protein Liquid Chromatography (FPLC), to separate the...

Abstract

Seasonal fluctuations of climate are considered a major factor affecting spermatogenesis and semen quality in the bovine. Our study aimed to investigate the effect of season on functional parameters of frozen-thawed bovine semen using computer-assisted sperm analysis (CASA) and flow cytometry. For...

Abstract

Heat stress has long been recognised as a cause of subfertility in farm animals. The objectives of the present study were to elucidate the effect of heat stress on sperm function and involvement of the mitogen-activated protein kinase (MAPK) 14 signalling pathway. Spermatozoa incubated for 4h at a...

Abstract

Testicular degeneration is the most frequent reproductive affection in males and leads to a decrease in sperm quality and, consequently, fertility. One of the main causes is heat stress, being characterized by the increase in the production of reactive oxygen species, thus, antioxidant substances...

Abstract

The role of heat shock protein in reproduction is widely known as a molecular chaperone in aiding and repairing protein formation when stress occurred. The present objectives were to evaluate the effect of different thawing temperature and time on the expression of HSP70 gene expression and the...

Abstract

The aim of this study was to describe the effect of temperature on the quality of bull's semen. Because today artificial insemination is used on a large scale, efforts should be made to obtain excellent semen from males. Bulls used for breeding are specific animals, to which the farmer must pay...

Abstract

In general, Taurus bulls under tropical conditions demonstrate reduced fertility due to heat and oxidative stress on testicular tissue. This high incidence of sperm damage is generally enhanced by the large amount of polyunsaturated fatty acids (PUFA) naturally present in bull sperm. Despite PUFA...

Abstract

Decreased conception rate of dairy cows in the summer is mainly associated with the deleterious effects of environmental thermal stress on the female reproductive tract. Here, we suggest that decreased reproductive performance might be partially due to inferior-quality semen. Semen from five...
