ELI5: Why are egg donors upheld to such strict requirements in order to donate?

Because the people who receive them want healthy eggs to produce healthy children, especially since they're paying for them. Messing up the eggs with drugs, excessive alcohol, and other unhealthy habits isn't fair to anyone involved.

Egg donors may be held to higher standards than sperm donors because sperm are constantly created and replenished, while a woman is born with all the egg cells she will ever have. Once those eggs are messed up, that's it.
