A highly purified follicle-stimulating hormone (FSH) preparation has been obtained from sheep pituitary glands by extraction with ethanol followed by fractionation with metaphosphoric acid and ammonium sulfate, gel filtration on Sephadex G-150, ion exchange chromatography on carboxymethyl Sephadex, hydroxylapatite chromatography, preparative acrylamide disc gel electrophoresis, and gel filtrati...

Cultured rat ovarian granulosa cells respond to follicle-stimulating hormone (FSH) by synthesizing and secreting plasminogen activator. The specificity of the response for FSH prompted us to explore the use of this system as an in vitro bioassay for FSH. The release of FSH by pituitary cell cultures has been examined by this method, as have been preparations of FSH of known biological activity....

The p subunit of follicle-stimulating hormone (FSH-@) from human pituitary glands was reduced and S-aminoethylated prior to thermolytic, tryptic, and chymotryptic digestions. Each digest was gel-filtered on Sephadex G-50 to separate the glycopeptides from the peptides. The glycopeptides and the peptides were isolated by high voltage paper electrophoresis at pH 6, 3.5, and 2.0. The purity of the...

the aim of the present study was to investigate the effect of follicle stimulating hormone (fsh) on survival, activation and growth of ovine primordial follicles using histological studies. pieces of ovine ovarian cortex were obtained and cultured for 6 days in minimum essential medium supplemented with or without fsh (50 ng/ml). these fragments were then process to be used for histology compar...

Objectives This study aimed to compare the presence of blepharitis, ocular tension (OT) with corneal thickness, refractive values and axial length changes in premenopausal postmenopausal women. Materials methods Thyroid-stimulating hormone (TSH), follicle-stimulating (FSH), luteinizing (LH), oestradiol (E2), prolactin, refractions horizontal vertical meridians, OT values, length, central thickn...

PURPOSE To evaluate the predictive power of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, testicular biopsy histology and male age were evaluated with respect to the success of sperm retrieval in a microdissection testicular sperm extraction (microTESE) procedure, pregnancy and live birth rates. MATERIALS AND METHODS We examined the data of 131 infertile men with...

background: anti-müllerian hormone (amh) is secreted by the granulosa cells of growing follicles during the primary to large antral follicle stages. abnormal levels of amh and follicle stimulating hormone (fsh) may indicate a woman’s diminished ability or inability to conceive. our aim is to investigate the changes in serum amh and fsh concentrations at different age groups and its correlation ...

The effects of treatment of patients with gonadotrophin-releasing hormone analogue (GnRHa) combined with purified follicle stimulating hormone (FSH) for in-vitro fertilization (IVF) were investigated in detail to determine the influences of different administration routes and the degree of suppression of luteinizing hormone (LH). Responses to exogenous gonadotrophins were studied in infertile w...
