In the slow block to polyspermy, eggs release material into the extracellular space, and within minutes of its release, this material transforms the egg from a gamete ready for sperm entry, to a structure unable to permit fertilization. The slow block is used by eggs from nearly all sexually reproducing animals.
Do humans have slow block to polyspermy?
Mammals have only this kind of slow block to polyspermy; it is called “the zona reaction”. Phenomena in humans and mammals tend to be called by special names even when the same phenomena also occur in lower animals. For example, the mammal vitelline membrane is called the zona pellucida.
What are the different types of polyspermy block?
Two types of mechanisms for polyspermy block have been reported: the “oocyte membrane block” to sperm penetration and the “zona reaction”.
