At what point do the eggs become fertilized?

[BHReptiles]

The 'eggs' are fertilized at ovulation. At that point, the follicles move into the oviducts and the female releases the sperm stored up (the more sperm...the better your chances at fertilization...thus the pairing early). Once the female releases the sperm, it's a giant free-for-all. 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.
