What is super sperm?
Super Sperm is a term used for where some males are producing fast and powerful sperm. The aggresive sperm is passing all the female defences and too many are penetrating and fertilizing the egg, called Polyspermy.
What prevents polyspermy from occurring?
polyspermy is a egg that was fertilized by multiple sperm. This is a major problem in most cells because due to this, there will be no sign of diploidy (2 set of chromosomes). The egg prevents this during the acrosomal process. The contact between the acrosome and the vitelline envelope triggers the egg to release Ca+ which changes the charge under the plasma membrane. This prevents other sperms from interacting. This is the first way that it is prevented. This way is often referred as the "Rapid Block" For the "Slow Block", The cortical granules inside the egg (they're like these tiny vesicles just under the plasma membrane) fuse with the egg plasma membrane. this in turn triggers swelling of the space betweel the vitelline envelope and the plasma membrane. Afterwards, the vitelline envelope hardens.
