The Follicle-Stimulating Hormone (FSH) Receptor in Testis: Interaction with FSH, Mechanism of Signal Transduction, and Properties of the Purified Receptor1

Ovarian response to follicle-stimulating hormone (FSH) stimulation depends on the FSH receptor genotype.

Because the ovarian response to FSH stimulation in assisted reproduction is variable, ranging from hyporesponse to hyperresponse, with the possible complication of ovarian hyperstimulation, it would be of great benefit to predict the response of the patients to FSH. To date, no clear-cut predictors of ovarian responsiveness to FSH have been identified. In this study, we investigated the role of...

Follicle-stimulating hormone (FSH) activates extracellular signal-regulated kinase phosphorylation independently of beta-arrestin- and dynamin-mediated FSH receptor internalization

BACKGROUND The follicle-stimulating hormone receptor (FSH-R) is a seven transmembrane spanning receptor (7TMR) which plays a crucial role in male and female reproduction. Upon FSH stimulation, the FSH-R activates the extracellular signal-regulated kinases (ERK). However, the mechanisms whereby the agonist-stimulated FSH-R activates ERK are poorly understood. In order to activate ERK, some 7 TMR...

FOLLICLE-STIMULATING HORMONE GLYCOFORM INTERACTIONS WITH THE FSH RECEPTOR A Thesis by

Follicle-stimulating hormone (FSH) and luteninizing hormone (LH) in the urine of prepubertal children.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) have been measured by specific bioassays in pooled urine samples from prepubertal children, aged 2-6 yr, and from male adults. For children the mean urinary excretion of FSH was 2.2 U 2nd International Reference Preparation (2nd IRP) per liter and the mean urinary excretion of LH was 0.44 U 2nd IRP per liter. For adults the mean FS...

Allosteric activation of the follicle-stimulating hormone (FSH) receptor by selective, nonpeptide agonists.

The pituitary glycoprotein hormones, luteinizing hormone and follicle-stimulating hormone (FSH), act through their cognate receptors to initiate a series of coordinated physiological events that results in germ cell maturation. Given the importance of FSH in regulating folliculogenesis and fertility, the development of FSH mimetics has been sought to treat infertility. Currently, purified and r...
