I’m talking about humans specifically here. During school I was always shown animations that showed many sperm swimming to an egg, and then when the first sperm started entering the egg (don’t even know how they do that, do they eat through?), the other sperm just stopped trying and gave up. How do the other sperm know? Are they sentient? What’s stopping loads of sperm going into the same egg? What would happen if 100 sperm went into the egg at once?
In: Biology
~~ From what I’ve heard, it’s the egg that let’s in the sperm ~~
~~ So technically, it might not be the first sperm that reaches the egg. ~~
~~ I also have no justification to this, so maybe someone who knows can explain? ~~
Edit: I did some research

From what’s stated, it’s not the egg choosing the specific sperm, but rather, sperm from a specific mate.
My bad.
Also, I believe this is just one study.
