[ 1 ] - P-119: In Vitro Assessment of Sucrose for Preservation of Buffalo Epididymal Spermatozoa
Background: Epididymal spermatozoa have been used for production of offspring from genetically important animals after they are dead. To attain optimal fertility with epididymal spermatozoa, they should be preserved in a suitable medium in 37°C. Preservation media provides requirement for spermatozoa and affects its motility, viability, and fertility. Sucrose is one of the important components ...
[ 2 ] - P-34: Effect of Glucose on Buffalo Epididymal Sperm Motion Characteristics, Viability and Cytoplsmic droplets During 24 Hours Incubation
Background: The recovery of sperm from the cauda epididymis may be the last chance to conserve, genetic Materials of valuable farm animals. Sperm utilize glucose as source of energy through glycolysis and oxidative phosphorylation to provide motility and movement. While endogenous glucose of the culture media has little potential to preserve sperm motility and viability for long period of time ...
[ 3 ] - P-70: Effect of Xylose on Epididymal Sperm Motility in Water Buffalo (Bubalus bubalis)
Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...
[ 4 ] - P-133: Effect of Thawing Rate on Kinetic Parameters of Frozen - Thawed Buffalo Spermatozoa Extended in Tris - Egg Yolk
Background: Optimal thawing rate is critical for quality and fertilizability of frozen -thawed spermatozoa. Kinetic parameters are the most important factors which are affected by thawing rate so, that have close relation between kinetic parameters and fertility of the spermatozoa. Tris - egg yolk have been widely used for cryopreservation of the buffalo and other species semen. According to ou...
[ 5 ] - P-134: In Vitro Assessment of Cysteine Effect on DNA Integrity of Frozen-Thawed Buffalo Spermatozoa
Background: Cysteine has been used as additive in cryopreservation extenders. It contains of thiol group which plays an antioxidant role to eliminate reactive oxygen species (ROS) during freeze -thaw procedure. Excessive ROS production cause DNA damage and subsequently reduce sperm fertility. On the other hand, protamine protein have high levels of cysteine which is critical in packaging and co...
