Phospholipids of bovine spermatozoa and seminal plasma.
Spermatozoal and seminal plasma lipids of fourteen individual bulls were separated by column chromatography into neutral lipid and several phospholipid fractions. Elution progress was monitored by thin-layer chromatography. Each phospholipid constituent was determined by phosphorus analysis. Total lipid, cholesterol and plasmalogen contents were determined. The fatty acids and aldehydes of the ...
متن کاملReactive Oxygen Species and Antioxidant in Seminal Plasma and Their Impact on Male Fertility
Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...
متن کاملMetabolism of phospholipids by spermatozoa and seminal plasma.
1. The hydrolysis of added (32)P-labelled phospholipids by whole ram and bull semen and the separated spermatozoal and plasma components was examined. 2. The ethanolamine phosphoglycerides were rapidly attacked by washed spermatozoa, forming predominantly glycerylphosphorylethanolamine, but with whole semen and seminal plasma a lysophosphatidylethanolamine was also detected. 3. The hydrolysis o...
متن کاملImpact of Seminal Chemical Elements on the Oxidative Balance in Bovine Seminal Plasma and Spermatozoa.
Mutual relationships between selected chemical elements (Na, K, Fe, Cu, Mg, and Zn), basic motility characteristics (motility and progressive motility), and markers of the oxidative balance (superoxide dismutase, catalase, glutathione, albumin, and malondialdehyde) were investigated in bovine seminal plasma and spermatozoa. Computer assisted sperm analysis was used to assess the motility parame...
متن کاملThe effect of seminal plasma on the quality of coated ram frozen-thawed spermatozoa
Two experiments were designed to examine the effects of crude seminal plasma (CSP) exposure ofejaculated and epididymal spermatozoa before freezing. Experiment 1, two consecutive ejaculates werecollected (n=4) within 5 min, the second one was carried out in a tube containing Fiser extender (coatedspermatozoa); by centrifugation, seminal plasma was removed from coated ejaculates. The pellets wer...
