Just in response to the question about whether it's possible to donate when you want to have more children in the future - my fertility clinic didn't seem fussed at all about this. I have a child already but have not closed my mind entirely to another in the future if that were to happen. However, I'm perfectly happy to have one child. I think it's certainly important to be aware that there is a risk of things going wrong because the process involves surgery and that's never guaranteed to be 100% safe, so maybe it's worth thinking about very carefully before making that decision. Then again, is there anything in life that's guaranteed? (Hope none of this sound negative! Just busy thinking through these issues myself, kind of thinking aloud.)
