Sperm pretreatment with heparin and L-glutathione, sex-sorting, and double cryopreservation to improve intracytoplasmic sperm injection in bovine
(Elsevier Science Inc, 2017-04)
In bovine, intracytoplasmic sperm injection (ICSI) remains inefficient partially due to low levels of sperm decondensation. The aim of this study was to determine whether the injection of normal size sperm pretreated with ...
Protective effect of melatonin on damage in the sperm parameters of mice exposed to diazinon Efecto protector de la melatonina sobre el daño en los parámetros espermáticos de ratones expuestos a diazinón
(2011)
Since normal sperm parameters can be altered by organophosphorous pesticides, this study intended to determine if melatonin is able to prevent the damage on sperm quality after an acute exposure to diazinon. Adult male ...
Pre-treatment of cattle sperm and/or oocyte with antibody to lipocalin type prostaglandin D synthase inhibits in vitro fertilization and increases sperm-oocyte binding
(ELSEVIER SCIENCE BV, 2008)
The present study was conducted to determine the affect of pre-treating of oocytes and/or sperm with a rabbit polyclonal antibody against recombinant cattle lipocalin type prostaglandin D synthase (alpha L-PGDS) on in vitro ...
Pentoxifylline effects on capacitation and fertility of stallion epididymal sperm
(Elsevier B.V., 2017-04-01)
The aims of this study were to determinate whether pentoxifylline (PTX) increases the motion parameters of fresh and frozen-thawed equine epididymal spermatozoa, to evaluate the tyrosine phosphorylation of frozen-thawed ...
Improved embryo development using high cysteamine concentration during IVM and sperm co-culture with COCs previous to ICSI in bovine
(Elsevier Science Inc, 2018-09)
In contrast to other species, intracytoplasmic sperm injection (ICSI) in bovine remains inefficient, resulting in low embryo developmental rates. It is unclear whether such inefficiency is due to the poor response of bovine ...
Melatonin prevents damage elicited by the organophosphorous pesticide diazinon on mouse sperm DNA
(2009)
Toxic effects of pesticides are commonly associated with DNA damage. To evaluate the effect of the organophosphate diazinon on sperm DNA and to test whether melatonin could prevent this damage, male mice were intraperitoneally ...
Mast cell-sperm interaction: evidence for tryptase and proteinase-activated receptors in the regulation of sperm motility
(Oxford University Press, 2003)
The detection of significant levels of tryptase in human seminal plasma and follicular fluid and of tryptase-positive mast cells (MCs) in the wall of human Fallopian tubes lead us to hypothesize that tryptase may exert ...
