Reduced levels of intracellular calcium releasing in spermatozoa from asthenozoospermic patients
BACKGROUND Asthenozoospermia is one of the most common findings present in infertile males characterized by reduced or absent sperm motility, but its aetiology remains unknown in most cases. In addition, calcium is one of the most important ions regulating sperm motility. In this study we have investigated the progesterone-evoked intracellular calcium signal in ejaculated spermatozoa from men w...
متن کاملReduced Serum Homocysteine Levels in Diabetic Patients
Background and Objectives: Type 2 diabetes is the most prevalent form of diabetes mellitus and is associated with a variety of complications. Homocysteine is an important independent risk factor for atherosclerotic diseases in both diabetic and non diabetic subjects. The association between these two is still unclear. The aim of this study was to assess the serum homocysteine levels in uncompli...
متن کاملProteomic profile of human spermatozoa in healthy and asthenozoospermic individuals
Asthenozoospermia is considered as a common cause of male infertility and characterized by reduced sperm motility. However, the molecular mechanism that impairs sperm motility remains unknown in most cases. In the present review, we briefly reviewed the proteome of spermatozoa and seminal plasma in asthenozoospermia and considered post-translational modifications in spermatozoa of asthenozoospe...
متن کاملSperm glyceraldehyde 3-phosphate dehydrogenase gene expression in asthenozoospermic spermatozoa
It has been suggested that the energy required for sperm motility is produced by oxidative phosphorylation while glycolysis seems to be an important source for ATP transmission along the flagellum. Some studies have investigated the chemical and kinetic properties of the enzyme glyceraldehyde 3-phosphate dehydrogenase to identify any changes in the regulation of glycolysis and sperm motility. I...
متن کاملLow expression of glycoprotein subunit 130 in ejaculated spermatozoa from asthenozoospermic men.
Previous studies showed that interleukin-6 (IL-6) was expressed in human Leydig and Sertoli cells and that it inhibited sperm motility. The aim of this study was to compare the expression of IL-6, IL-6R, and GP130 in ejaculated spermatozoa between normozoospermic and asthenozoospermic men. Human spermatozoa in the semen were purified by Percoll gradient technique to separate the seminal plasma ...
