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...

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”

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 ...
