Species difference in the expression of Fas and Fas ligand in mature mammalian spermatozoa
sperm Fas antigen FasL
2017/12/25
Although it has been proposed that the Fas and Fas ligand (FasL) may protect ejaculated spermatozoa against apoptosis induced by lipoperoxidative damage and against lymphocytes present in the female g...
Effect of low-density lipoprotein addition to soybean lecithin-based extenders on bull spermatozoa following freezing-thawing–preliminary results
bull sperm cryopreservation sperm motility viability cryoprotectant
2016/12/20
Soybean lecithin-based extenders represent an alternative to extenders containing egg yolk, but there has been discussion about their cryoprotective efficacy. Low-density lipoprotein (LDL) was proved ...
Lead induced alterations in rabbit spermatozoa motility and morphology in vitro
reproductive toxicity rabbit Pb temperature sperm motility morphological abnormality
2016/11/11
The aim of this in vitro study was to determine the effect of lead chloride (PbCl2) on rabbit spermatozoa motility and morphology. Lead concentrations in the medium ranged between 0.45 and 11.17 μg/ml...

The effect of adding high or low protein content homologous seminal plasma to boar spermatozoa on the progressive motility of the spermatozoa after storage for three days, and at a 1 : 4 dilution rati...
Kinetics of hydrogen peroxide generated from live and dead ram spermatozoa and the effects of catalase and oxidase substrates addition
reactive oxygen species ram antioxidant
2016/1/29
The generation of hydrogen peroxide (H2O2) by ram spermatozoa (spz) was measured using a flurometric assay with 10-acetyl-3,7-dihydroxyphenoxazine agent as a probe for H2O2 detection. The kinetics of ...
Relationship between acrosome integrity changes and in vitro fertilising ability of bovine spermatozoa
bull spermatozoa acrosome embryos IVF
2015/10/9

Exploration of natural cryoprotectants for cryopreservation of African catfish, Clarias gariepinus, Burchell 1822 (Pisces: Clariidae) spermatozoa
egg yolk honey glucose coconut water
2015/7/7
Toxicity is a major limitation to successful spermatozoa cryopreservation of fish. Due to this
problem, it is critical to find potential cryoprotectants which are more environmental-friendly, non-to...
Oxidative stress and motility in tench Tinca tinca spermatozoa
tench sperm activating medium osmolality
2015/7/7
It was hypothesized that sperm hypotonic exposure can provoke oxidative
stress which could be involved in sperm quality degradation. Our study aimed to describe spermatozoa motility
parameters and...
