Secretion of plasminogen activator in response to follicle-stimulating hormone in culture medium of human testicular cells from biopsy specimens
plasminogen activator follicle-stimulating hormone culture medium human testicular cells
2009/2/23
Testicular cells from human biopsy specimens were cultured and plasminogen activator secreted into the medium was investigated. Follicle stimulating hormone stimulated plasminogen activator secret...
Inhibition of ornithine decarboxylase activity by follicle stimulating hormone in primary culture of rat Sertoli cells
ornithine decarboxylase follicle stimulating
2009/2/23
The effect of follicle stimulating hormone on the activity of ornithine decarboxylase (ODC) was determined in primary culture of rat Sertoli cells. Three different FSH preparations (NIH oFSH-S-15, S...

Follicle stimulating hormone luteinizing hormone testicular Leydig cell estradiol immunization Ile-de-France rams
2009/2/23
Active immunization of Ile-de-France rams against estradiol (E2) resulted in the production of E2-neutralizing antibodies and an elevation in the plasma concentrations of FSH, LH, and testosterone...
Orchiectomy in young rats results in differential regulation of follicle-stimulating hormone and luteinizing hormone content
LH FSH synthesis regulation
2009/2/20
While it is generally accepted that GnRH stimulates release of pituitary gonadotropins, it is not clear what regulates synthesis. The orchiectomized immature rat, with sustained high plasma levels o...
Clinical studies in an adult male patient with “isolated follicle stimulating hormone （FSH）deficiency”
isolated FSH deficiency gonadotropin deficiency hypogonadism infertility FSH deficiency
2009/2/20
Previous reports concerning isolated follicle stimulating hormone (FSH) deficiency and its possible pathogenesis have been conflicting. Both "normal" and "abnormal" FSH response to luteinizing hormone...

2009/2/20
The effect of exogenous follicle stimulating hormone (FSH) on testicular function was studied in twenty 4-month-old Holstein bulls during two seasons (ten in late winter and ten in summer). Five mg ...
Regulation of testicular ornithine decarboxylase in vitro. Effect of age, follicle-stimulating hormone, and luteinizing hormone

Follicle-stimulating Hormone Receptor Binding Inhibitors in Human Seminal Plasma
FSH binding inhibition seminal plasma
2009/2/19
Human seminal plasma, freed of spermatozoa by centrifugation, inhibited binding of iodine-125 (125I)-hFSH to receptors in calf testes. Binding inhibition (BI) was seen in seminal plasma from intact ...

Follicle-stimulating hormone and testosterone stimulation of immature and mature Sertoli cells in vitro：inhibin and N-cadherin levels and round spermatid binding
Follicle-stimulating hormone testosterone stimulation immature mature Sertoli cells
2009/2/18
The in vitro response of Sertoli cells isolated from adult rat testes to testosterone (T) and follicle-stimulating hormone (FSH) treatment was investigated. Sertoli cells from >70-day-old Sprague-...
