1. Human seminal plasma and posterior lobe of prostate was found to have phospholipase A2 (PLA2) activity hydrolysing phosphatidylethanolamine with 14C-labelled linoleic and arachidonic acid. 2. A negative relationship was between sperm count and PLA2 activity in human seminal plasma. 3. The purified PLA2 from human seminal plasma showed high affinity to heparin, sensitivity toward p-bromophenacyl bromide, Pb2+, dithioerythritol and EDTA and it was activated by Ca2+ and Mn2+. 4. The purified PLA2 had alkaline pH optimum (7.5-10.0) and pI-value of 5.3. In SDS-PAGE enzyme preparation resulted in two bands with mol. wt of 14,000 and 16,000.
