Spurious elevation of follicle‐stimulating hormone
Acta Obstetricia et Gynecologica Scandinavica, 1992Serum concentrations of follicle‐stimulating hormone (FSH) were measured in a 33‐year‐old eurnenorrhoeic woman with primary infertility. Postmenopausal levels were obtained. Using an alternative assay, the patient was found to have normal levels of FSH. The probable cause of the misleading result is discussed.

Follicle stimulating hormone as a predictor of fertility
Current Opinion in Obstetrics and Gynaecology, 1998Tests for diminished ovarian reserve provide valuable prognostic information for women considering assisted reproductive technology. The best characterized screening tool for a general infertility patient is the clomiphene citrate challenge test. These screening tests do not have absolute sensitivity or specificity.

Recombinant Follicle Stimulating Hormone
1990Follicle Stimulated Hormone (FSH) α and s genes have been isolated. The genes were inserted into a single vector such that expression is directed by two juxtaposed transcription units. The DNA has subsequently been transferred to Chinese Hamster Ovary (CHO) cells and transfected cell clones have been isolated.

Regulation of Follicle-Stimulating Hormone Receptor
Hormone Research, 1996The acquisition of follicle-stimulating hormone (FSH) receptors during folliculogenesis is believed to be a key event in follicle development. We have examined the effects of FSH and activin on FSH receptor mRNA in cultured rat granulosa cells. Treatment of granulosa cells with FSH resulted in transient suppression of the FSH receptor mRNA levels 2-6 h

Receptors | Thyroid-Stimulating Hormone/Luteinizing Hormone/Follicle-Stimulating Hormone Receptors
2021The thyroid-stimulating hormone receptor (TSHR), luteinizing hormone receptor (LHCGR), and follicle-stimulating hormone receptor (FSHR) are collectively referred to as the glycoprotein hormone receptors because they bind structurally similar glycoprotein hormones.

Follicle-stimulating-hormone receptor and twinning
The Lancet, 2001Sir—Ayman Al-Hendy and colleagues report on the association between mutations of the follicle-stimulatinghormone receptor (FSHR) (Sept 9, p 914) and repeated twinning. They describe a woman, bearing two mutations in the receptor, one change at position 307 (alanine to threonine) and the other with a change at position 680 (asparagine to serine), who ...

1994
A glycopeptide (M.Wt. 32 KDa) containing about 18% carbohydrate. In common with other pituitary hormones TSH, LH and the placental hormone hCG, it comprises a- and β-subunits, the α-subunit being common to all 4 peptide hormones. Biological activity is lost on dissociation of the subunits.

The Follicle Stimulating Hormone Receptor
1990Regulation and maintenance of Sertoli cell functions essential for spermatogenesis are primarily dependent on follitropin (FSH), a glycoprotein hormone that is elaborated by the anterior pituitary gland. The initial event in follitropin action is the specific binding of the hormone by high affinity follitropin receptors present on the Sertoli cell ...

Biosynthesis and Secretion of Follicle-Stimulating Hormone*
Endocrine Reviews, 1983THE ANTERIOR pituitary gland synthesizes and secretes three glycoprotein hormones. Two of these, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are termed gonadotropins and exert divergent effects upon the gonads to regulate and maintain essential reproductive processes such as gametogenesis, steroidogenesis, and ovulation.

Norepinephrine in Graafian Follicles Is Depleted by Follicle-Stimulating Hormone*
Endocrinology, 1982The purpose of the present study was to measure norepinephrine (NE) in Graafian follicles and correlate changes in its concentration with circulating gonadotropins secreted endogenously or administered exogenously. Graafian follicles were removed from the ovaries of adult cycling rats. The follicles were pooled in groups of 10-13, and NE was determined
