abstract background: sperm parameters and motion kinetics are affected by cryopreservation. objective: the main purpose of the current study was to determine the effect of different concentrations of trolox as an antioxidant to freezing-thawing procedure on human sperm kinematic parameter. materials and methods: semen was collected from 20 normal donors and divided into five aliquots prior to c...

in order to determine iron and lead content of seminal plasma in water buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls. the semen characteristics were evaluated; its iron and lead content were estimated by atomic absorption spectrophotometer. the iron and lead content of the seminal plasma (mean ± sem) was recorded as...

black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

background: pentoxifylline (px) is a methyxanthin derivative that influences the sperm motion characteristics. in general, px has been reportedly effective in preserving sperm motility in vitro, also when administered orally to the asthenozoospermic patients. objective: the main objective of this prospective clinical trial study was to rule out the effect of oral administration of px on sperm p...

Background: The application of laparoscopic method for intrauterine insemination is limited in sheep industry by the high cost of equipment and low pregnancy rate of frozen-thawed spermatozoa. Both disadvantages could be decreased if chilled ram semen is transported to the farms and inseminated through cervix. Semen extender provides the requirements for sperm and affects its motility, viabilit...

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...
