چکیده مقاله:

This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly significant differences (P

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...

P-18: Effects of Ethanol Consumption on Chromatin Condensation and DNA Integrity of Epididymal Spermatozoa In Rat

Background: Alcohol abuse is considered as one of the problems associated with poor semen production and sperm quality. Both acute and chronic alcohol consumption may affect spermatozoal chromatin disorders through apoptosis. Therefore, for the first time, this experimental study was performed to evaluate the effect of ethanol consumption on sperm parameters and chromatin integrity of spermatoz...

Effect of Bovine Serum Albumin on Motility, Plasmalemma, Viability and Chromatin Integrity of Buffalo Bull Spermatozoa

The present work was designed to study the effect of different concentrations of bovine serum albumin (BSA) in extender on post-thaw quality of buffalo spermatozoa. Semen was collected from three buffalo bulls with artificial vagina (42°C) for three weeks (replicates). Qualifying semen ejaculate from each bull was split into five aliquots and diluted in tris-citric egg yolk extender containing ...

Effect of chromatin condensation on frozen-thawed sperm DNA integrity in normozoospermic men

Background and Aim: Sperm cryopreservation is a common technique used for management of male infertility. But this method has detrimental effects on sperm DNA and chromatin quality. Evaluation of different markers associated with the health of genetic material of sperm is beneficial for determination of the fertility of sperm. The aim of this study was to assess the effect of sperm chromatin co...
