Hormonal regulation of spermatogenesis in the hypophysectomized rat：FSH maintenance of cellular viability during pubertal spermatogenesis
Testis testosterone hypohysectomy cellviability
2009/2/17
The potential for follicle-stimulating hormone (FSH) to promote germ-cell survival and the cellular sites of FSH action were studied using a gonadally maturing (pubertal), hypophysectomized (Hx) rat...
Androgenic maintenance of the rat erectile response via a non-nitric-oxide-dependent pathway
Penile erection testosterone cGMP phosphodiesterase
2009/2/17
Prior studies have demonstrated that the erectile response in the rat penis is androgen dependent and is mediated by nitric oxide (NO), the neurotransmitter synthesized by the enzyme nitric oxide ...
Quantitative maintenance of spermatogenesis in cyclosporine-treated rats by exogenous administration of testosterone propionate
Testosterone cyclosporine spermatogenesis
2009/2/6
The authors had previously shown that the subcutaneous administration of cyclosporine (CsA) resulted in an impairment of spermatogenesis. Testosterone levels declined and gonadotropin levels increas...
Characterization of sulfhydryl proteins involved in the maintenance of flagellar straightness in hamster spermatozoa
sperm flagella motility sulfhydryl proteins
2009/2/6
Hamster caput epididymal spermatozoa exhibit a marked 90-180 degree bend when induced to acquire progressive motility in vitro (Cornwall et al, 1988). Flagellar bending is prevented by oxidizing spe...
Calcification of the Epididymis and the Tunica Albuginea of the Corpora Cavernosa in Patients on Maintenance Hemodialysis
Peyronie disease chronic renal failure hemodialysis ultrasonography epididymis end-stage renal disease
2008/12/22
The aims of this study were to determine the incidence rates of genital calcification in male hemodialysis patients based on ultrasonography findings and to identify risk factors for this conditio...
