I'm glad that Lois & Clark are discussing the ramifications of this decision - I am reminded, however, of a Sci-Fi story from many years ago (I think Heinlein but could have been McCaffrey) where a young couple who were space explorers neglected to bank eggs and sperm in the event they returned from their mission sterile. The husband dies but the wife desperately wants a child. The solution given was an egg donation from her mother's banked eggs and sperm from his father's donation.
