Current Concepts of Follicle-Stimulating Hormone Receptor Gene Regulation1

the frequency of follicle stimulating hormone receptor gene polymorphisms in iranian infertile men with azoospermia

background: azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. follicle stimulating hormone (fsh) is a member of the glycoprotein hormone family that plays an important role in human reproduction because of its essential role in normal spermatogenesis. various single nucleotide polymorphisms (snps) have been reported within fsh receptor (fshr) g...

Bioactive Follicle-Stimulating Hormone

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 FSH biosynthesis, storage, secretion, serum concentrati...

Properties of follicle-stimulating hormone-receptor interactions. Specific binding of human follicle-stimulating hormone to rat testes.

Some properties of the interaction between radioiodinated human follicle stimulating hormone (lz51-hFSH) and its specific receptors in preparations of rat seminiferous tubule homogenate are described. Specific binding of lz51-hFSH by seminiferous tubule homogenate was appreciably greater than to Leydig cell homogenate of rat testes. The uptake of rz51-hFSH was hormone specific and uptake inhibi...

Effect of follicle-stimulating hormone receptor N680S polymorphism on the efficacy of follicle-stimulating hormone stimulation on donor ovarian response.

OBJECTIVE The aim of this study was to investigate whether N680S FSHR polymorphism has a predictive value for the ovarian response to stimulation with gonadotropins and cycle outcome in our egg donor program. METHODS The oocyte donor candidates were selected according to the Instituto Bernabeu egg donation program requirements and ASRM and ESHRE guidelines for oocyte donation. The FSHR polymo...
