Choice of staining technique affects the morphological assessment of epididymal feline sperm
Felis catus cat spermatozoa morphology eosin-nigrosin stain Giemsa-Wright stain
2016/11/11
Morphological examination of spermatozoa remains a valuable tool for determining the quality of feline sperm for cryopreservation and/or for use in artificial insemination. Numerous staining technique...
Relationships between selected sperm characteristics and fertilisation success in the beluga sturgeon,Huso huso (Linnaeus, 1758)
sperm quality parameters fertilisation hatching Huso huso
2015/10/9
We examined the relationships between a number of sperm characteristics (motility, concentration and pH) and sperm fertility (egg fertilisation and hatching rate) in 10 mature females and four mature ...
The structure and role of mammalian sperm RNA: a review
sperm spermatozoal RNA fertilisation
2015/4/17
The main role of sperm is the delivery of the paternal genome into the oocyte during fertilisation. However, several lines of evidence have indicated that mammalian spermatozoa contribute more than ju...

dogs sperm sperm viability necrosis flow cytometry
2015/4/15
The influence of selected semen extenders on the motility of frozen-thawed dog spermatozoa has been clearly demonstrated in several studies, although there are no reports indicating the effect of swim...
The interrelationship between quality parameters of sperm before and after separation by gradient centrifugation
bull sperm qualitative separation
2015/3/13
Significance of a short-time survival test for the prediction of quality parameters of sperm obtained by gradient centrifugation was evaluated from an aspect of their functional resistance. Frozen sem...

Tyrosine Phosphorylation Events Mouse Sperm
2014/10/23
Mammalian sperm are not able to fertilize immediately upon ejaculation; they become fertilization-competent after undergoing changes in the female reproductive tract collectively termed capacitation. ...
Changes in the mRNA Expressions of Sperm Transforming Growth Factor β-isoforms and their Receptors with Reference to Fertility during in vitro Storage of Fowl Semen
