At what point do the eggs become fertilized?

Now, there's no guarantee the sperm will fertilize the follicles at ovulation. They could all miss or she might not release the sperm at all (thus getting all slugs).


at least...that's my understanding.

Nope, not at all.
They are slugs from early on, they do not turn into slugs if they don't become fertilized.
I've heard the theory about slugs being caused by males, doesn't make any sense to me at all.
If you palpate, early on especially, but even later too, you can feel slugs far before ovulation.
If the female doesn't store any sperm, or doesn't release the stored sperm you would have infertile eggs.

if im understanding right the sperm meets the eggs at ovulation(at which point the eggs are 30mm+)

The follicles are typically about 44mm at ovulation.
