Figure 4: Transmission electron microscopy reveals docking of epididymosomes on the sperm plasma membrane to allow delivery of GPI-linked proteins to the sperm surface via hydrophobic interactions.23 On the smaller epididymosome SPAM1 which is immunogold- labeled is seen in the process of being transferred to the sperm membrane, while the contact of the larger epididymosomes appears to involve membrane fusion.
