If you've had a tubal ligation (tubes tied), you're still releasing eggs every month and your eggs are still intact, so you can still donate eggs. The important points are you must be aged 29 or less, you must have a pretty impressive resume (educational background, or at least high scores on standardized tests, and be able to present yourself very well, interview well, and be very attractive in appearance to future couples/women interested in paying $20,000 for some of your eggs) - it is very much a beauty contest from what I've read. My thinking is that the type of women these companies want to donate their eggs, are precisely the type of women who probably would not need the money in the first place, so I'd think the ideal woman's eggs they're looking for are going to be a very rare find.
