Male infertility is a multifactorial complex disease with highly heterogeneous phenotypic
representation and in at least 15% of cases, this condition is related to known genetic …

Introduction Infertility is a major health problem, worldwide, which affects 10–15% of
couples. About half a percent of infertility cases are related to male-related factors. Male …

Objective Oxidative stress plays a key role in the pathogenesis of male infertility. But, the
adverse effects of oxidative biomarkers on sperm quality remain unclear. This study aimed to …

Background In recent years, oxidative stress has been studied extensively as a main
contributing factor to male infertility. Nitric Oxide, a highly reactive free radical gas, is …

Recent studies on the eNOS gene and male infertility show that expression of eNOS
regulates normal spermatogenesis in the testis, and the eNOS gene variants (T-786C, 4a4b …

Contents The aim of the study was to screen the entire bull genome to identify markers and
candidate genes underlying sperm concentration. The analysed data set originates from a …

Results of recent studies confirmed that oxidative stress negatively affects sperm motility and
causes sperm DNA damage. Produced by nitric oxide synthase 3 (NOS 3), nitric oxide is …

Objective To assess endothelial nitric oxide synthase (eNOS) gene polymorphism
relationship with semen parameters and oxidative stress in infertile …

In testis, eNOS is responsible for synthesis of nitric oxide (NO) which is an essential gas
message regulator in spermatogenesis, suggesting that eNOS gene plays a role in normal …

Background: Varicocele is an abnormal enlargement of the pampiniform venous plexus in
the scrotum. Varicocele is the most common cause of secondary male infertility. Nitric oxide …
