Induction of varicocele in the dog：I. Partial ligation of the left renal vein does not induce a varicocele in the dog
varicocele in the dog left renal vein varicocele dog
2009/2/23
Induction of varicocele was attempted by partial ligation of the left renal vein in 10 male dogs. The effects on sperm count, sperm motility, and sperm morphology, as well as on hemodynamics, were a...
Same day appearance of orally administered, spermicidal 1-substituted imidazoles in dog ejaculates
orally administered spermicidal 1-substituted imidazoles dog ejaculates
2009/2/23
Within hours after administration of high oral doses of ketoconazole to males of various species, the intact compound appears in the seminal plasma, leading to immobilization of spermatozoa in eja...
Scrotal hypothermia and testicular blood flow in the dog
hypothermia testicle blood flow thermal
2009/2/20
Two clinically tolerable methods of producing testicular hypothermia have been studied in dogs. Evaporative cooling produced a 3.7 degree fall and ice water a 9.7 degree fall in intratesticular te...
Identification of arginine esterase as the major androgen-dependent protein secreted by dog prostate and preliminary molecular characterization in seminal plasma
arginine esterase dog prostate seminal
2009/2/20
This work was undertaken to determine the identity of the major androgen-dependent 15,000 molecular weight protein previously observed on SDS polyacrylamide gel electrophoresis of both dog prostate ...
Regulation of gonadotropin secretion in the male dog. Role of estradiol
gonadotropin secretion male dog
2009/2/19
Steroid regulation of pituitary LH and FSH secretion in the male may be mediated via the direct action of testosterone, or via the conversion of testosterone to either dihydrotestosterone (DHT) or e...
Testosterone Pretreatment and the Response of Pituitary LH to Gonadotropin-Releasing Hormone（GnRH）in the Male Dog
GnRH LH-response testosterone dog
2009/2/19
To characterize the effects of testosterone (T) pretreatment on the response of pituitary LH secretion to exogenous gonadotropin-releasing hormone (GnRH), intact male dogs were injected subcutaneo...
Testosterone Regulation of Follicle-stimulating Hormone Secretion in the Male Dog
testosterone FSH polydimethylsiloxane
2009/2/18
Studies were carried out to determine the effect of various numbers of testosterone-filled polydimethylsiloxane (PDS)capsules on plasma concentrations of testosterone and FSH in acutely orchidectomi...
Acrosome reaction in dog sperm is induced by a membrane-localized progesterone receptor
Canine spermatozoa prostatic fluid
2009/2/18
The aim of this study was to investigate whether the dog sperm acrosome reaction can be induced by progesterone and whether the action of progesterone is mediated by binding of progesterone to a r...
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...
150-kDa proteins in dog serum bind 1.5-kDa growth-promoting factors for androgen-independent canine prostatic epithelial cells
150-kDa proteins dog serum bind 1.5-kDa growth-promoting factors androgen-independent
2009/2/12
Fractions obtained by gel filtration or ultrafiltration of dog serum were tested for their mitogenic activity on canine prostatic epithelial cells: two prostatic growth factor (PGF) entities were fo...
Specific Order in the Appearance of Protein Tyrosine Phosphorylation Patterns Is Functionally Coordinated With Dog Sperm Hyperactivation and Capacitation
Kinetics hyperactivation membrane destabilization sperm function phosphorylation
2008/12/19
The aims of the present study were to characterize a slow capacitation system that records initial changes in the sperm membrane state, and, using a canine model, to order the specific protein tyros...
Rapid Disappearance of Spermatozoa After Vasal Occlusion in the Dog
Vasectomy sperm clearance canine
2008/12/19
The reproductive system of the male dog is unusual in that the seminal vesicles and bulbourethral glands are absent. Therefore, we chose the dog as a model to evaluate the effect of seminal vesicl...
