Association of molecular variants of luteinizing hormone with male infertility.

Luteinizing hormone (LH) stimulates the interstitial Leydig cells to produce testosterone, which is essential for spermatogenesis. Abnormalities in the function of LH may affect the process of spermatogenesis and thus result in infertility. The aim of this study was to determine the association of three known variants of LH (Gln54Arg [Trp8Arg; Ile15Thr] and Gly102Ser) with male infertility. A t...

Association of the genetic variants of luteinizing hormone, luteinizing hormone receptor and polycystic ovary syndrome

BACKGROUND High circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioactivity of these hormones. The aim of this study was determine the role of the LH and LHR polymorphisms in the pathogenesis of PCOS using a genetic approach...

Strong association of SLC1A1 and DPF3 gene variants with idiopathic male infertility in Han Chinese

Male infertility is a multifactorial syndrome encompassing a wide variety of disorders. In recent years, several genome-wide single-nucleotide polymorphism (SNP) association studies (GWAS) have been performed on azoospermia and/or oligozoospermia in different populations including two GWAS on nonobstructive azoospermia in China; however, the association of SNPs with idiopathic male infertility,...

Genetic association of UBE2B variants with susceptibility to male infertility in a Northeast Chinese population.

The ubiquitin-conjugating enzyme 2B gene (UBE2B) is involved in the regular and symmetric organization of the fibrous sheath of sperm flagella. This study aimed to examine the relationship between single nucleotide polymorphisms (SNPs) in UBE2B and infertility in Northeast Chinese men. We carried out a polymerase chain reaction-restriction fragment length polymorphism analysis for SNPs in 312 f...

Association the study of between CGA rs6631A>T gene polymorphism with the risk of male infertility

 Introduction: The CGA gene encodes alpha subunit of glycoprotein hormones that are involved in the fertility process. The aim of this study was to evaluate the relationship between glycoprotein hormones, alpha polypeptide (CGA)  rs6631A> T gene polymorphism with the risk of men with azoospermia or severe oligozoospermia. Methods:  This study was conducted in a case-control study on 200 bloo...
