Ouch eugenics...that's a never a good idea with people, I'm a man but if my partner had a problem unless it was major and definitly genetically heritable I would never dream of nicking some perfect woman's egg to fertilise- that's just not the way kids ought to be brought into the world unless there is a fertility problem.
