the aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (casa). the semen samples were collected from three ghezel rams. samples were diluted in seminal plasma (sp), phosphate-buffered saline (pbs) containing 1% bovine serum albumin (bsa) and bioexcell. the motility parameters that computed and rec...

The aim of this study was to determine the effects of co-Q10 and ellagic acid on sperm parameters after the freeze–thawing of Ghezel ram sperm. Twenty ejaculates from five Ghezel rams were collected in this study. Semen samples, which were diluted with a soybean lecithin (SL) based extender containing 0.25 mM ellagic acid, 0.5 μM co-Q10, 0.25 mM ellagic acid + 0.5 μM co-Q10 and no antioxidant (...

The aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (CASA). The semen samples were collected from three Ghezel rams. Samples were diluted in seminal plasma (SP), phosphate-buffered saline (PBS) containing 1% bovine serum albumin (BSA) and Bioexcell.

to evaluate the effects of calcium on motility patterns of bovine epididymal sperm and to determine the effective calcium concentration, ovine testicles (5 for each experiment day) were picked up in a local slaughterhouse and transported to the laboratory in a cool container (filled wich ice).in laboratory,caudal epididymis was incised and sperm cells were put into petri dishes containing modif...

Background: Epididymal sperm has been recovered with the aim of conserving potentially valuable genetics Materialss from post mortem males for subsequent usage in assisted reproduction technologies. Among the quality parameters of spermatozoa, motility and velocity patterns are sensitive for chemical and physical components of medium which they were diluted. Also close correlation between sperm...

objective: the aim of the present study was to investigate the effects of four equilibration times (2, 4, 8 and 16 hours) and two extenders (tris or bioxcell®) on cryopreservation of buffalo semen. materials and methods: in this experimental study, split pooled ejaculates (n=4), possessing more than 70% visual sperm motility were divided in two aliquots and diluted in bioxcell ® and tris-citric...

objective: adiponectin and its receptors (adipor1 and adipor2), known as adiponectin system, have some proven roles in the fat and glucose metabolisms. several studies have shown that adiponectin can be considered as a candidate in linking metabolism to testicular function. in this regard, we evaluated the correlation between sperm mrna abundance of adiponectin and its receptors, with sperm mot...

Background: Detection of sperm parameters based on conventional methods, immediately after thawing, have been revealed sperm capacity to in vivo and in vitro fertilization. But this evaluation is not fully reliable because of long journey of sperm during female genital tract to reach the oocyte and fertilize it. Therefore, analyzing postthawed sperm parameters after incubation is more beneficia...
