What a brave, kind thing to do, hat's off to you Vodka!
If I'm guessing right, there will be more than on egg to harvest, have you considered maybe putting a few of them "on ice" for yourself? You never know. Pregnancy and delivery is the easiest part as Mazie said earlier, all you need to do is remember to pick up your dignity once you leave the labour ward! The scary bit comes after the delivery, but it is well worth it.
Good luck with whatever you decide to do.
