eli5 – Does “best sperm wins the race” actualy change anything?

569 views

I think we all know that the best, fastest sperm wins the race to become the child whatever whatever. My question is does it actually make a difference for the kid. Would there be any difference if it was just a random one, not the first one? I’m wondering if the sperm cell being first has any correlation to the human being more functional or anything.

Your premise is wrong, the best sperm does not necessarily win the race, it’s mostly just the sperm that wins the race wins the race. Most describe it as luck and fitness combined, if it was fitness alone, it would be highly repeatable for the same sperm to win the race (the Usain Bolt of Sperm would always win), luck would be more random which sperm in a group wins (i.e. a bunch of Joe sperm walking down a road and one doesn’t happen to get distracted and go into shop or murdered on the way to the egg). In actuality it is somewhere in between these scenarios.

Your question-does it make a difference for the kid which sperm wins? Absolutely, sperm are genetically unique and will bestowe a different set of traits into the child.
