Inhibin production by Sertoli cells during testicular regression in the golden hamster
Inhibin production Sertoli cells testicular regression golden hamster
2009/2/23
The objective of this study was to determine if testicular regression in the hamster results in changes in Sertoli cell function that reflect altered pituitary function. Inhibin-like activity was me...
Effects of Experimentally Induced Hyperprolactinemia on the Hypothalamus, Pituitary, and Testes in the Golden Hamster
hyperprolactinemia hypothalamus pituitary testis prolactin follicle-stimulating hormone norepinephrine testosterone dopamine luteinizing hormone releasing hormone
2009/2/19
Hyperprolactinemia was induced in adult male golden hamsters by transplantation of four homologous pituitaries under the renal capsules. The resulting elevation of plasma prolactin (PRL) levels wa...
Nuclear Uptake and Retention of Androgen by the Accessory Organs in the Male Golden Hamster
androgens 3H-dihydrotestosterone autoradiography male accessory organs
2009/2/18
The nuclear uptake and retention of 3H-dihydrotestosterone (3H-DHT) were studied in the reproductive organs of the male hamster by autoradiography. Castrated adult male hamsters were injected with...
Testicular function after local injection of 6-hydroxydopamine or norepinephrine in the golden hamster（Mesocricetus auratus）
golden hamster testis innervation norepinephrine 6-hydroxydopamine LH-receptors
2009/2/6
Although there is evidence for the sympathetic innervation of the mammalian testis, the function of noradrenergic fibers is not understood. This in vivo and in vitro study in the adult golden hamste...
Addition of hypotaurine can reactivate immotile golden hamster spermatozoa
hypotaurine epinephrine penicillamine
2009/2/6
Hamster epididymal spermatozoa became virtually immotile following washing and dilution in chemically defined medium (TLP-PVA). The sperm motility factors (penicillamine, hypotaurine, and epinephrin...
Testicular secretion of inhibin in the male golden hamster（Mesocricetus auratus）
inhibin male golden hamster
2008/12/26
To identify the cellular source of inhibin in the male golden hamster, we have used complementary approaches, immunohistochemistry and enzyme-linked immunosorbent assay (ELISA). Strong positive stai...
The Stimulatory Role of Estrogen on Sperm Motility in the Male Golden Hamster（Mesocricetus auratus）
Estrogen immunization gonadotropin
2008/12/23
To clarify the physiological roles of estrogens in the regulation of sperm motility in the golden hamster, two different approaches were used. In the first experiment, silastic tubes containing ei...
Male Genital Tract Antioxidant Enzymes: Their Source, Function in the Female，and Ability to Preserve Sperm DNA Integrity in the Golden Hamster
Superoxide dismutase glutathione peroxidase catalase sperm DNA damage oxidative stress Syrian hamster
2008/12/19
Recently, we reported that male accessory sex gland (ASG) secretions protect sperm genomic integrity by demonstrating that DNA damage was more extensive in sperm not exposed to the secretions. The p...
Inhibin B Regulating Follicle-Stimulating Hormone Secretion During Testicular Recrudescence in the Male Golden Hamster
Photoperiod proliferating cell nuclear antigen sperm motion
2008/12/16
In the present study, to clarify whether inhibin affects follicle-stimulating hormone (FSH) secretion in the recrudescence of the male golden hamster, we used a recently developed specific enzyme-link...
