Egg donation though. Completely different story. I start thinking about it and I find myself in a moral quagmire.
I think it is because sperm is almost infinite, out it comes and by the next day the pot has been topped up. Eggs, however, are far more finite. You get what you are born with and, with each passing month, they start to disappear (in fact the lions share disappear whilst still in the womb).
I don't have an answer. And I'm not really sure where the post goes but (as the comments on the last post show - thanks for that I was expecting a far more negative response), you're a thoughtful bunch and I'd be interested to hear your take.
By the way, I know the opening sound like something that I have exaggerated for effect but I promise, it was totally unexpected and word for word what happened.
