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...

Protective effect of vitamin D on Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), testosterone hormones and testicular tissue changes induced by methotrexate in adult male rats

Background and Aims: Vitamin D has antioxidant and anti-inflammatory activities. The present study aimed to investigate the protective effect of vitamin D on Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), testosterone hormones and testicular tissue changes induced by methotrexate in adult male rats. Materials and Methods: In this experimental study, 30 adult male Wistar rats wei...

Follicle-stimulating hormone-releasing factor (FSH-RF) and luteinizing hormone-releasing factor (LH-RF) in rat hypothalamic extract.

Hypothalamic tissues of female rats were extracted with 1.M acetic acid. The acidic extract was lyophilized and subjected to gel filtration on Sephadex column and assayed for follicle-stimulating hormone-releasing factor (FSH-RF) activity and luteinizing hormone-releasing factor (LH-RF) activity by estimating FSH and LH using the organ culture method of rat anterior pituitaries. FSH activity wa...

Follicle stimulating hormone (FSH) and luteinizing hormone (LH) gene expression during larval development in Senegalese sole (Solea senegalensis).

The gonadotropins (GTHs), follicle stimulating hormone (FSH) and luteinizing hormone (LH), determine the reproductive competence of adult breeders, but also participate in the establishment of the reproductive axis at early stages of life. The present study aimed at studying, by real-time qPCR, the gene expression levels of GTH subunits (FSHbeta, LHbeta and the common glycoprotein alpha -GPalph...

Further evidence for differential regulation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH): increased FSH and decreased LH levels in a patient with familial pure gonadal dysgenesis.

There is experimental evidence that a portion of follicle-stimulating hormone (FSH) secretion is independent of hypothalamic influences. A 29 year old woman with familial pure gonadal dysgenesis developed myelodysplastic syndrome. Endocrine investigations showed discrepancy between serum FSH and luteinizing hormone (LH) levels. FSH levels remained elevated while LH levels decreased. The FSH to ...
