A step-by-step guide for service providers showing how to involve young people. It looks at how to identify the real sexual and reproductive health needs of young people; how to analyse what is being ...
Involvement of endothelial nitric oxide synthase in the impaired endothelium-dependent relaxation of cavernous smooth muscle in hypercholesterolemic rabbit
Hypercholesterolemia cavernous smooth muscle
2009/2/18
The present study was designed to evaluate whether functional impairment and/or protein expression of constitutive nitric oxide synthase (cNOS; endothelial NOS [eNOS] and neuronal NOS[nNOS]) was i...
Involvement of reactive oxygen species in human sperm arcosome reaction induced by A23187, lysophosphatidylcholine, and biological fluid ultrafiltrates
Hydrogen peroxide catalase superoxide dismutase chemiluminescence
2009/2/18
Although recent evidence indicated that the production of reactive oxygen species (ROS) by human spermatozoa may be involved in the regulation of capacitation, very little is known about the role ...
Potential involvement of kallikrein hK2 in the hydrolysis of the human seminal vesicle proteins after ejaculation
Seminal plasma semenogelin fibronectin protein C
2009/2/17
We have recently demonstrated in liquefied human seminal plasma the presence of the novel kallikrein hK2 in association with protein C inhibitor (PCI) as a 75-kDa complex. In the present study, we s...
Mechanism of stress-induced attenuation of the testicular response to gonadotropin：possible involvement of testicular opioids, a pertussis toxin-sensitive G-protein, and phosphodiesterase
stress-induced attenuation possible involvement testicular opioids pertussis toxin-sensitive G-protein
2009/2/16
This study examined the potential role of testicular opioids, a pertussis toxin (PT)-sensitive G-protein, and phosphodiesterase in mediating the inhibitory effect of immobilization stress on testi...
Involvement of vasoactive intestinal peptide（VIP）as a humoral mediator of penile erectile function in the dog
vasoactive intestinal peptide（VIP） humoral mediator penile erectile function dog
2009/2/12
The effects of intracorporeal infusion of anti-vasoactive intestinal peptide (anti-VIP) antisera on electrically induced penile erection were studied in 18 male mongrel dogs. Electrical pulse stimul...
Involvement of inhibin in the regulation of follicle-stimulating hormone secretion in the young adult male Shiba goat
Involvement of inhibin follicle-stimulating hormone secretion young adult male Shiba goat
2008/12/25
The roles of inhibin and testosterone in the regulation of gonadotropin secretion were investigated in young adult male Shiba goats (8-12 months of age). Plasma levels of inhibin but not testoster...
The mouse sperm glycine receptor/chloride channel：cellular localization and involvement in the acrosome reaction initiated by glycine
mouse sperm glycine receptor/chloride channel cellular localization involvement glycine
2008/12/25
Previously, we reported that glycine initiates the in vitro acrosome reaction (AR) of porcine and human sperm by a mechanism that includes the glycine receptor/Cl- channel (GlyR) and that this recep...
Male Infertility：No Evidence of Involvement of Androgen Receptor Gene Among Indian Men
Azoospermia oligozoospermia oligoteratozoospermia spermatogenesis
2008/12/23
Spermatogenesis is collaboratively controlled by testosterone and follicle stimulating hormone. Testosterone and its immediate metabolite dihydrotestosterone affect their roles through the androge...
Involvement of A1 Adenosine Receptors in the Acquisition of Fertilizing Capacity
A1 adenosine receptors KO mice A1 adenosine receptors mouse sperm localization capacitation caffeine fertility
2008/12/22
Ejaculated mammalian spermatozoa acquire competence to fertilize oocytes by a two-step process: capacitation followed by acrosome reaction. The biochemical and biophysical modifications occurring ...
Involvement of Cytoplasmic Free Calcium in Boar Sperm: Head-to-Head Agglutination Induced by a Cell-Permeable Cyclic Adenosine Monophosphate Analog
Capacitation BAPTA thapsigargin fluo-3 Ca2+-ATPase
2008/12/18
When boar spermatozoa are incubated in a medium designed for in vitro fertilization, many of them become agglutinated at the acrosomes. We previously reported that bicarbonate and cyclic adenosine...
