Asthenozoospermia (ASZ) is a condition characterized by reduced sperm motility in semen affecting approximately 19% of infertile men. Major risk factors, particularly gene mutations, still remain unknown. The main aim of the present study was to identify novel genes and mutations that Sperm motility is an important prerequisite for successful fertilization and is regulated by cyclic AMP activated protein kinase A which phosphorylates flagella proteins like axonemal dynein and initiates motility. Increase in calcium influx reverses this process by dephosphorylation that is
This study introduces a method for assessing the individual degree of oxidative stress (integral indicator) in men with pathospermia and type 1 diabetes, based on lipid peroxidation parameters. The study population consisted of three groups of patients. The study group included 15 men with type 1
Semen abnormality (SA) male infertility has become a worldwide reproductive health problem. The invasive tests (e.g., testicular biopsy) and labor-intensive methods of semen collection severely inhibit diagnosis of male infertility. In addition, the pathogenesis and biological interpretation of male
This study aimed to report a rare case of intermittent azoospermia and ring-like small supernumerary marker chromosomes (sSMCs). An infertile man was diagnosed with azoospermia presenting a normal male phenotype with complete masculinization. Karyotyping and polymerase chain reaction (PCR) were used
Carbohydrates are known to mediate some events involved in successful fertilization. Although some studies on the glycosylation of seminal plasma proteins are available, the total glycan profile was rarely analyzed as a feature influencing fertilization potential. In this work we aimed to compare
