abstract background: sperm cells extracted from testes (tese) have poor chromatin quality and motility. various substances are used in the laboratory to increase sperm motility and improve the art outcomes; however, there are few research which considered improving both sperm motility and chromatin quality. objective: the aim of this investigation was to evaluate the improvement of the testicul...

DOI: 10.5812/atr.7245 Implication for health policy/practice/research/medical education: The role of trauma in the modern society has a vital importance and significance role that resorting to any facilities and strategies to handle the dilemma seems worthful for all researchers in this s...

Motility parameters of the spermatozoa in most fish species spawning in fresh water like Rutilus kutum lasts for a short time after activation. Ovarian fluid significantly influenced sperm motility (motility duration period) and percent motility (progressive forward motile sperm). Both of these variables generally increased as the concentration of ovarian fluid increased from 33% to 50%, respec...

The aim of this study was to evaluate changes that occur in motility parameters of progesterone treated mouse spermatozoa during course of hyperactivation. Mouse spermatozoa treated with different doses of progesterone were videotaped after 10 min and 90 min of incubation. For each sperm, one second of movement of the head-midpiece junction was traced from the videotape and for each tracing sev...

In this study, sperm characteristics (motility parameters and ionic composition of seminal plasma) and effect of ions on motility (duration of motility of sperm and percentage of motile spermatozoa) and fertilization capacity (fertilization rate, hatching rate, survival rate and larvae length) were investigated in Ctenopharyngdon idella. The longest duration of motility obtained in solution con...

Background: Taurine regulates an unusual number of biological phenomena,including heart rhythm, contractile function, blood pressure, platelet aggregation, neuronal excitability and body temperature. It appears to be a sperm motility factor (SMF), although the mechanism that maintains motility has apparently not been elucidated. It may act by alterations in either ion transport (osmoregulation)...
