The posterior region of the sperm head (the post-acrosomal region) undergoes changes during post-testicular maturation in the epididymides. , 2002). Enzymes that have been reported to be present in the acrosome include: hyaluronidase, proacrosin, acrosin, esterases, neuraminidase, acid phosphatase, phospholipases, aryl phosphatase, b-Nacetylglucosaminidase, arylamidase, collagenase 36 A.
