Novel Variants in UBE2B Gene and Idiopathic Male Infertility

Genetic Variation of Choline Dehydrogenase Gene in Idiopathic Male Infertility

Infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. There is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. Choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...

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...

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,...

Interactions between Urinary 4-tert-Octylphenol Levels and Metabolism Enzyme Gene Variants on Idiopathic Male Infertility

Octylphenol (OP) and Trichlorophenol (TCP) act as endocrine disruptors and have effects on male reproductive function. We studied the interactions between 4-tert-Octylphenol (4-t-OP), 4-n- Octylphenol (4-n-OP), 2,3,4-Trichlorophenol (2,3,4-TCP), 2,4,5-Trichlorophenol (2,4,5-TCP) urinary exposure levels and polymorphisms in selected xenobiotic metabolism enzyme genes among 589 idiopathic male in...
