"Three catalytically active cPLA2 iPLA2 and sPLA2 are expressed in different areas within the human spermatozoon cell body. Spermatozoa with a significant low motility showed strong differences both in terms of total specific activity and of different intracellular distribution compared with normal spermatozoa. Phospholipases could be potential biomarkers of asthenozoospermia."xsd:string
