Thanks SD2001 for your insights. Especially as a man and a donor. Initially I wanted to respond by saying that I thought you had a very cinical viewpoint, but I guess you might be right, and not everyone's All Sweetness and Light! I've very much thought about the reality of what's involve in egg and sperm donation, had counselling and thought long and hard about it, but the difference being that my donor will be known to my 'fingers crossed' future family. And my donor has told me she's very commited in giving us the eggs needed (even if it's more than one stim cycle) to have however many children we've hoped for, but she's requested that her eggs only be used for us and that we don't, later down the track, donate them (which we may have done otherwise).
