background: extracted sperm from the testis have poor motility. moreover, their motility changes during their journey through epidydimis. meanwhile, they face high concentration of l-carnitin. in addition, lactate dehydrogenase c4 (ldh-c4) gene disorders has been shown to cause impaired sperm motility, leading to infertility in male mice. the aim of this study was to evaluate sperm motility and...

the purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and dna damage). semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. five healthy buffalo bulls (5 ejaculates from ...

Objective(s): Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial membrane potential (MMP) in varicoceli...

Background Lipid peroxidation is known to cause various impairments to sperm cells and may play a major role in the etiology of male infertility. Asthenospermia is the main factor of male infertility and has significantly higher level of peroxidation than in normozoospermic males. MaterialsAndMethods Using thiobarbituric acid (TBA) assay procedure, we have determined the level of lipid peroxida...

Objective Metals can cause male infertility through affection of spermatogenesis and sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is mediated via various mechanisms such as production of reactive oxygen species (ROS). Flavonoids have antioxidant and metal chelating properties which make them suitable candidates for neutralizing adverse effects of metals ...

Background and Objective: Infertility is a health problem that affects 72.4 million couples worldwide. Infertility can occur due to an unhealthy lifestyle, such as a smoking habit. A cigarette contains nicotine, a toxic compound that can trigger oxidative stress and eventually decrease fertility. Temulawak is a medicinal plant that is rich in antioxidants and anti-inflammatory properties. It ha...

This study aimed to assess the effect of genetic and seasonal interaction on semen quality in Artificial Insemination Center. A total 36,754 ejaculation records were evaluated. The dependent variable was which consisted volume, pH, concentration, abnormalities, motility fresh semen. independent variables age, season, number ejaculation. mixed procedure with Tukey–Kramer multiple comparison test...
