Follicle Stimulating Hormone Receptor (FSHR) Polymorphisms and Polycystic Ovary Syndrome (PCOS)

open access: yesFrontiers in Endocrinology, 2019
Polycystic ovary syndrome (PCOS) is the commonest endocrine abnormality in women of reproductive age typically presenting with chronic oligo- or anovulation, clinical, or biochemical hyperandrogenism and polycystic ovarian morphology (PCOM).

Follicle-Stimulating Hormone-Secreting Pituitary Adenomas [PDF]

open access: yesThe Journal of Clinical Endocrinology & Metabolism, 1985
This retrospective study concerns 40 patients with an apparently nonsecretory pituitary adenoma who were operated on during an 11-yr period from 1971 to 1981. Among them, 6 men had elevated serum FSH levels. LH levels were normal in 5 and slightly elevated in 1. Testosterone levels were low in 2 patients and within normal limits in 2 others.

Follicular and endocrine dose responses according to anti-Müllerian hormone levels in IVF patients treated with a novel human recombinant FSH (FE 999049) [PDF]

open access: yes, 2015
Objective: To study the association between serum anti-Mullerian hormone (AMH) levels and follicular development and endocrine responses induced by increasing doses (5.2-12.1 mu g/day) of a novel recombinant human FSH (rhFSH, FE 999049) in patients ...

Bioactive follicle-stimulating hormone [PDF]

open access: yesTrends in Endocrinology & Metabolism, 1991
Abstract Specific and sensitive in vitro bioassays suitable for measurement of follicle-stimulating hormone (FSH) in small quantities of serum and urine have recently been validated. Comparisons of bioassay (B-FSH) potencies with immunoassay (I-FSH) estimates and chromatofocusing patterns have facilitated new discoveries regarding the regulation of ...

Structure-Function Relationships of the Follicle-Stimulating Hormone Receptor

open access: yesFrontiers in Endocrinology, 2018
The follicle-stimulating hormone receptor (FSHR) plays a crucial role in reproduction. This structurally complex receptor is a member of the G-protein coupled receptor (GPCR) superfamily of membrane receptors.

Consequences of twinning induction to Noemi ewes by a recombinant human follicle-stimulating hormone compared with pituitary-derived porcine follicle-stimulating hormone on follicular dynamics, maternal biochemical attributes, and neonatal traits [PDF]

open access: yesVeterinary World, 2020
Aim: The aim of this study was to investigate the effectiveness of using recombinant human follicle-stimulating hormone (FSH) compared with pituitary-derived porcine FSH given as one dose or multiple doses on the neonatal traits, follicular dynamics, and

The 'incidentaloma' of the pituitary gland. Is neurosurgery required? [PDF]

open access: yes, 1990
We describe a series of 18 patients with an intrasellar mass incidentally discovered by computed tomography or magnetic resonance imaging. The average size of the mass was 13 mm, with a range from 5 to 25 mm.

Androgen Stimulates Growth of Mouse Preantral Follicles In Vitro: Interaction With Follicle-Stimulating Hormone and With Growth Factors of the TGFβ Superfamily

open access: yesEndocrinology, 2017
Androgens are essential for the normal function of mature antral follicles but also have a role in the early stages of follicle development. Polycystic ovary syndrome (PCOS), the most common cause of anovulatory infertility, is characterized by androgen ...
