Suppression of growth hormone does not affect ongoing spermatogenesis in rats
Suppression of growth hormone ongoing spermatogenesis rats
2009/2/18
Recent evidence suggests that growth hormone (GH) may enhance physiologic processes, such as spermatogenesis, in addition to causing classical anabolic effects. We have previously shown that testost...
Extender components and surfactants affect boar sperm function and membrane behavior during cryopreservation
Extender components surfactants boar sperm function membrane behavior cryopreservation
2009/2/18
To determine how the individual components of extenders affected boar sperm function and membrane structure and to test a new surfactant's cryoprotective ability, boar sperm were cryopreserved in ...
Hexokinase present in human sperm is not tyrosine phosphorylated but its antibodies affect fertilizing capacity
Hexokinase human sperm fertilization infertility
2009/2/16
The present study was conducted to investigate the presence of hexokinase in human sperm cell, its subcellular localization, its modulation and role in capacitation/acrosome reaction, and tyrosine...
Cryopreservation extenders affect calcium flux in bovine spermatozoa during a temperature challenge
Milk egg yolk-Tris indo-1 acetoxymethyl ester cold
2009/2/13
Bovine spermatozoa are commercially cryopreserved by diluting the cells in media, known as extenders, followed by slow cooling and freezing. Previous work has shown that this process of cryopreser...
Circulating and luminal testicular factors affect LRP-2 and Apo J expression in the epididymis following efferent duct ligation
Circulating luminal testicular factors LRP-2 Apo J epididymis
2008/12/25
Apolipoprotein J (clusterin or sulfated glycoprotein-2) has been shown to be secreted by the epididymal principal cells, whereupon it binds to sperm in the lumen. Apolipoprotein J also is endocyto...
The Motility of Epididymal or Testicular Spermatozoa Does Not Directly Affect IVF/ICSI Pregnancy Outcomes
Azoospermia infertility epididymal sperm testicular sperm
2008/12/23
Our objective was to determine whether the presence of motility in surgically obtained sperm samples improves fertilization and pregnancy rates for patients undergoing in vitro fertilization/intracy...
A Different Female Partner Does Not Affect the Success of Second Vasectomy Reversal
Infertility vasovasostomy microsurgery sterilization reversal testes
2008/12/22
The aim of the study was to determine whether the pregnancy rate with the same female partner or younger partners was higher compared with different or older partners after undergoing repeated vasec...
Inhibitors of Phosphoinositide 3-Kinase, LY294002 and Wortmannin, Affect Sperm Capacitation and Associated Phosphorylation of Proteins Differently：Ca2+-Dependent Divergences
Spermatozoa signal transduction Akt
2008/12/22
Sperm capacitation is regulated by multiple pathways that also control sperm motility and tyrosine (Tyr) phosphorylation of several sperm proteins. Among the reported pathways, phosphoinositide 3-ki...
Sperm Morphology and Preparation Method Affect Bovine Embryonic Development
Percoll swim-up abnormal spermatozoa thermal insult in vitro fertilization
2008/12/22
This study was conducted to evaluate the effect of sperm separation methods of semen samples collected from bulls subjected to scrotal insulation on embryonic development after in vitro fertilizat...
