The lipid composition of the sperm membrane has a significant effect upon the functional characteristics of spermatozoa. In the present study we investigated the fatty acid (FA) composition of subpopulations of spermatozoa separated on a discontinuous Percoll gradient (47:90%) and the FA composition of phospholipids (PL) of sperm heads and tails in both normal and abnormal semen samples. In nor...
Dear Editor, Asthenozoospermia is a common cause of decreased male fertility, and several factors can inhibit or prevent sperm motility, including ultrastructural defects of the sperm flagellum.1 An ultrastructural defect leading to severe asthenozoospermia is a syndrome called dysplasia of the fibrous sheath (DFS),1 which results in short, thick, and irregular sperm tails; this feature is caus...
Background: Pentoxifylline (PX) is a methyxanthin derivative that influences the sperm motion characteristics. In general, PX has been reportedly effective in preserving sperm motility in vitro, also when administered orally to the asthenozoospermic patients. Objective: The main objective of this prospective clinical trial study was to rule out the effect of oral administration of PX on sperm p...
