“…It has been demonstrated that prostasomes fuse with spermatozoa resulting in the loss of identifiable discrete prostasomal particles, 18 resulting in the transfer of enzyme activity, 19,20 altered membrane fluidity, 21 and changes in the acrosome reaction. 2 This work has shown that these interactions are favoured at slightly acidic conditions: it occurs optimally at pH 5.0-5.5, and is abolished by pH 8.0.…”

“…[45][46][47] Both spermatozoa and prostasomes display a netnegative surface charge when analysed in free-zone electrophoresis, and on comparison, prostasomes are slightly less negative than spermatozoa. 45 The interaction that can occur between prostasomes and spermatozoa is rather strong and most probably of a hydrophobic nature.…”

“…48 The fusion was cationindependent, but pH-dependent and required one or more proteins on sperm and prostasome surfaces. 49 A fusion means a transfer of lipids 46 and proteins 50 from prostasomes to spermatozoa. Further, an increase of sperm Ca 2+ was proportional to the prostasomal fusion with spermatozoa.…”
