My understanding (I'm a doctor but NOT an expert in this area) is that it usually is a long, difficult journey to the egg, and the chance of many getting there at exactly the same time is low. When a spermatozoan buries into the egg a reaction is caused which prevents other sperm from being able to penetrate.
An expert may be able to clarify, but I think this is the gist of it.

- gpvos 8y agoI thought that was general knowledge. It certainly was part of the sexual education I got at school.

- gowld 8y agoSometimes, after many years, some people forget some of the irrelevant details of their education. Do you remember all the steps in the ATP cycle?
- lugg 8y ago"Not so irrelevant now is it" Your teacher, maybe.
