The lack of effect of tumor necrosis factor-alpha, interleukin-1-alpha, and interferon-gamma on human sperm motility in vitro
Tumor necrosis factor interleukin-1 interferon human sperm motility
2009/2/10
Whether cytokines present in human peritoneal fluid reduce sperm motility, and thus contribute to infertility, is investigated. The human recombinant cytokines, tumor necrosis factor-alpha, interl...
Evaluation of human sperm hyperactivated motility and its relationship with the zona-free hamster oocyte sperm penetration assay
Motility capacitation fertilizing capacity
2009/2/7
The authors studied hyperactivated motility of human spermatozoa as a method of evaluating capacitation by examining its relationship to results of zona-free hamster oocyte sperm penetration assays ...
Relationship between sperm motility assessed with the Hamilton-Thorn motility analyzer and fertilization rates in vitro
sperm motility Hamilton-Thorn motility analyzer fertilization rates
2009/2/7
To determine which sperm movement characteristics are related to in vitro fertilization rates, semen and swim-up preparations used for in vitro fertilization in 108 patients were assessed using the ...
Longitudinal study of semen quality of unexposed workers Sperm motility characteristics
semen quality unexposed workers Sperm motility characteristics
2009/2/7
As part of a longitudinal study of human semen characteristics of unexposed workers, sperm motility measurements were made using computer-assisted sperm analysis. Motility analyses were conducted on...

domestic cat sperm morphology teratospermia
2009/2/6
Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (grea...
Human sperm motion analysis by automatic（Hamilton-Thorn Motility Analyzer）and manual（Image-80）digitization systems
human sperm motility computerized motion analysis calcium
2009/1/5
Two systems allowing quantitative, objective analysis of sperm movement were compared: 1) the Hamilton-Thorn Motility Analyzer (HTM), in which sperm images are digitized automatically, and 2) the Im...
Osmotic tolerance of equine spermatozoa and the effects of soluble cryoprotectants on equine sperm motility, viability, and mitochondrial membrane potential
Sperm osmotic stress horse cryopreservation glycerol
2008/12/29
Osmotic stress attributed to differences in the relative permeability of cryoprotectants, such as glycerol and water, appears to be an important factor in cryodamage. The objective of this study was...
Effects of dietary selenium on sperm motility in healthy men
Semen volume hypothyroidism nutrition selenium
2008/12/29
A deficiency of dietary selenium leads to immotile, deformed sperm and infertility in rats, whereas supplementation of the diet with selenium compounds has been associated with both beneficial and d...
The role of glucose in supporting motility and capacitation in human spermatozoa
Acrosome reaction ATP hamster oocyte penetration
2008/12/29
Glucose has been reported to be beneficial to human sperm for optimal capacitation and fertilization, although it is unclear whether glucose is required for providing extra metabolic energy through gl...
Susceptibility of glycolytic enzyme activity and motility of spermatozoa from rat, mouse, and human to inhibition by proven and putative chlorinated antifertility compounds in vitro
glycolytic enzyme activity motility spermatozoa rat mouse human inhibition
2008/12/26
Nonhormonal contraceptives that act by blocking energy metabolism within sperm have the advantage over spermatogenic inhibitors by their fast onset of infertility and their almost immediate restorat...
