Sperm motility stimulation is a pharmacological treatment used to improve sperm motility and treatment outcome in frozen-thawed epididymal and testicular spermatozoa. Sperm motility is a critical factor in male fertility. Low motility can be caused by a variety factors including abnormal spermatogenesis, oxidative damage, or depletion of intracellular adenosine triphosphate (ATP; molecule that ...

A study on motility of spermatozoa of the Persian sturgeon, Acipenser persicus were carried out. The time of relative cessation of sperm activity was evaluated using microscopic observation. Sperm was activated with three different swimming medium, freshwater pH 7.5, and two different buffered saline solutions, pH 7.5. Total period of the motility of A. persicus spermatozoa was shorter in fresh...

BACKGROUND Curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. The molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. Since modulation of intracellular pH (pHi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and m...

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...

background & objectives : the purpose of this study was to compare the success rate of intracytoplasmic sperm injection cycles (icsi) between infertile war victims & other infertile couples . materials & methods :this retrospective study was done on 672 infertile couples in kossar fertility & impotence center from 2000-2002. poisson, chi-square & t–test were used to compare the icsi results in ...

the freezing and thawing process not only is associated with serious damage to sperm such as damage to the plasma membrane and the acrosomal membrane but also changes the membrane permeability to some ions including calcium. also, the generation of oxygen free radicals is increased during the freezing-thawing process. the purpose of this study was to evaluate of the effects of trolox as an anti...

We previously demonstrated that osmolality isotonic to the seminal plasma suppresses sperm motility in marine and freshwater teleosts, and exposure of sperm to hypertonicity of sea water or hypotonicity of fresh water, respectively, induces the initiation of sperm motility at spawning. The motile sperm became immotile by return of osmolality to the isotonic osmolality both in a marine teleost, ...

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 testicular sperm ...
