Purification and characterization of chicken follicle-stimulating hormone.

Purification and partial characterization of isoforms of luteinizing hormone from the chicken pituitary gland.

Isoforms of chicken luteinizing hormone (cLH) were isolated from chicken pituitaries by differential extraction, sequential chromatography on HPLC cation- and anion-exchange columns, and gel-filtration chromatography. Three purified isoforms of the cLH had high biological potency in the chicken granulosa cell LH bioassay (4.21-7.4 x NIH-LH-S1 U/mg). One cLH isoform without detectable biological...

The Correlations of Anti-Mullerian Hormone, Follicle-Stimulating Hormone and Antral Follicle Count in Different Age Groups of Infertile Women

Identification and characterization of chickenII - GnRH ( cII - GnRH ) gene of Catla catla ( Hamilton , 1822 )

Gonadotropin-releasing hormone (GnRH) is a neuropeptide hormone responsible for the release of luteinizing hormone (Lh) and follicle-stimulating hormone (Fsh) from the anterior pituitary gland . GnRH have been identified and characterized from the brain of C. catla. A cDNA fragment of 202bp was amplified and GnRH variant has been identified in the form chicken-II-type gonadotropin-releasing hor...

Evaluation of Ovarian Reserve by Measurement of the Serum Levels of Anti-Mullerian Hormone and Follicle-Stimulating Hormone in Intracytoplasmic Sperm Injection Cycles

Background It is important to evaluate ovarian reserves prior to intracytoplasmic sperm injection (ICSI) treatment. The aim of this study is to determine the accuracy of anti-mullerian hormone (AMH) as a marker for ovarian reserve and to compare it with day-3 serum follicle-stimulating hormone (FSH) levels. MaterialsAndMethods In this analytic, corss-sectional study, sequential sampling was don...

Age-Specific Serum Anti-Mullerian Hormone and Follicle Stimulating Hormone Concentrations in Infertile Iranian Women

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 w...
