[Phospholipids of human seminal plasma and their role in ensuring fertility].

The phospholipid composition of seminal plasma from health (n = 13) and infertile men (n = 49) was studied. A significant decrease of lyso-phosphatidyl choline and lyso-phosphatidyl serine levels in seminal plasma of men with relative infertility was shown. Two-fold enhancement of phosphatidyl serine in seminal plasma of men with excretory infertility was found. A significant decrease of lyso-phosphatidyl choline in men with associated infertility was determined. An essential decrease of lyso-phosphatidyl serine and lyso-phosphatidyl choline in men with secretory infertility were shown. The level of phospholipids correlated with some morphological and functional characteristics of ejaculate.
