Follicle stimulating hormone (FSH) is a pituitary expressed glycoprotein hormone that regulates reproduction in mammals which composed of α and β-sub unit. The β-sub unit dictates its binding specificity with their receptor (FSHR). This study aimed to identify polymorphism of FSH β-sub unit and FSHR genes, and its effect to superovulatory response traits on superovulated cows. Study was done on...

Resistance ovarian syndrome is a heterogeneous disorder inherited as a Mendelian recessive trait and characterized by infertility, primary amenorrhea, normal karyotype and elevated serum FSH and LH levels. An inactivating mutation, C566T, in FSH receptor gene (FSHR) has been identified initially in Finland. We investigated if an adenovirus expressing a normal copy of human FSHR (Ad-hFSHR) has t...

BACKGROUND The identification of polymorphisms associated with a disease can help to elucidate its pathogenesis, and this knowledge can be used to improve prognosis for women with a particular disorder, such as polycystic ovary syndrome (PCOS). Since an altered response to ovarian stimulation is also a characteristic of the disease, further knowledge about its aetiology could help in defining t...

Introduction . Normal ovarian reserve (OR) determining the response to follicle development containing fully-featured oocytes is an important factor in pregnancy, including assisted reproductive technology (ART) programs. The causes of premature OR decrease are multifactorial. study gene polymorphism as a cause deserves attention. Aim : determine genetic predisposition and create prognostic mod...

Follicle-stimulating hormone (FSH) is fundamental for Sertoli cell function stimulating spermatogenesis and follicular growth by a specific receptor (FSHR). This work aimed to investigate the occurrence of Asn and Ser FSHR gene variants and its relationship with seminal anti-Müllerian hormone (AMH) among normozoospermic and infertile oligoasthenozoospermic (OAT) males. Eighty-two Caucasian male...

Follicle-stimulating hormone receptor (FSHR), which mediates the functioning of FSH, plays a central role in reproduction. We investigated bovine FSHR gene polymorphisms and analyzed their relationships with pregnancy rates after embryo transfer and with hormone concentrations on the day of embryo transfer. One reported SNP of FSHR, G-278A, located in the 5'-upstream region, was analyzed and th...

Abstract Background The gene expression of anti-Mullerian hormone receptor type 2 ( AMHR2 ) and follicle stimulating (FSHR) in cumulus cells (CCs) isolated from mature immature oocytes was studied as a possible non-invasive approach for determining oocyte maturity quality. CCs 100 infertile women with different etiologic factors were subdivided into control (CCs MII) case GV) group. Q-PCR used ...

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...

Transcripts and protein for follicle-stimulating hormone receptor (FSHR) were demonstrated in abdominal adipose tissue of female chickens. There was no expression of the Fsh gene, but FSH and FSHR colocalized, suggesting that FSH was receptor bound. Partial correlations indicted that changes in abdominal fat (AF) content were most directly correlated with Fshr mRNA expression, and the latter wa...

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...
