Background: Quercetin is a strong antioxidant and long-term treatment of STZ-diabetic animals and it has been shown to reduce oxidative stress.   Objective: antioxidants have essential effect on spermatogenesis and sperm parameters. Enhanced oxidative stress and changes in antioxidant capacity are considered to play an important role in the pathogenesis of chronic diabetes mellitus.   Methods...

This study was designed to analyze boar sperm to compare motility, acrosome morphology, viability and ATP by various preservation methods between Duroc boar A with cold shock resistance sperm and Duroc boar B with cold shock sensitivity sperm. Semen volume, sperm concentration, motility and normal acrosome between Duroc boar A and B did not show any differences within 2 h after collection. Ther...

Background: Sperm mediated gene transfer was approved for producing transgenic animals. There are many studies which reported different success rate by this procedure. Failure in this project mostly is returned to transfection and stability of transferred genes. The other problem that may contribute in project failure may return to the testicular damages which occur at the time of transfection,...

Background: Several studies have recently investigated the role of leptin, the polypeptide hormone secreted primarily by white adipose tissue, in the reproduction of rodents, humans, and domestic animals. Materials and Methods: To investigate the in vitro effect of leptin on buffalo semen quality in equilibrated and frozen thawed semen, five healthy buffalo bulls (5 ejaculates from each bull) w...

Sperm quality plays an important role in vertebrates in determining which male has the advantage when two or more males compete to fertilize a female's ova. In insects, however, the importance of sperm quality has never been considered, despite sperm competition being widespread and well studied in this group. We tested the hypothesis that sperm viability, measured as the proportion of live spe...

 The Indian riverine buffaloes are more susceptible to variations in the environment. These variations affect seminal plasma proteins, which in turn affect fertility. This study was conducted to evaluate variations in the Indian Bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) during winter and summer seasons, and its relation wit...

the aim of this study was to investigate the effect of adding different levels of zinc sulfate in semen extender on bovine sperm quality during cryopreservation. semen was collected from 4 holstein bull twice a week and the proper samples were pooled. semen were allocated to four extender treatments consisted of 0, 50, 100, 150 µm of zinc sulfate in 5 replicates and then, were frozen. post-thaw...
