You don't have to "hyperstimulate" anyone's ovaries to produce more eggs - you were born with all the eggs you'll ever have, and you don't produce any more during your lifetime. Assuming you're a woman, that is, which seems a safe assumption from your handle ;)
All fertility drugs do is increase the rate at which they are released from the ovary. If you want an egg just to play with, you don't need to administer any drugs that I know of - all you have to do is go extract them directly from the ovary.
