title: Interaction of lipids with the plasma membrane of sperm cells. III. Antifusigenic effect by phosphatidylserine.
abstract: Addition of 10% phosphatidylserine to dipalmitoyl-phosphatidylcholine liposomes, containing 3H-cholesterol or 14C-phosphatidylcholine, inhibited interactions between liposomes and rabbit spermatozoa. Phosphatidylserine also caused an apparent decrease in the inhibitory effect of cholesterol-bearing liposomes on sperm fertilizing ability.
