Wow this really took off all of a sudden.
I think it has, in fact, helped me to move past the tiny possibility of egg donation in my own situation. I think the payment levels, unlike surrogacy, are not sufficient to truly be the only motivator to give eggs - and indeed, having experienced infertility, I would if I could be comfortable donating my eggs myself, in another life. So, unlike surrogacy, my own conclusion is that finances alone aren't sufficient to explain egg donation.
However, I think it is clear there are SOME, though limited, risks, and I am not comfortable knowing I have chosen to place those risks on another woman. For me, that's the primary reason for deciding against it.
In relation to 'genetic heritage' I don't think there is a universal experience of how important or unimportant genetics are to one's identity. Amongst the adopted people I know, some placed enormous emphasis on their genetic heritage, while others had zero interest in looking into it. I suspect any young person who experiences a feeling of 'not belonging' may cling to their donor heritage as the reason for this - much as an adopted child might - even if this is not at all a part of the reason for their lack of belonging. I think for most children it is unlikely to cause much distress. Children generally need stable, loving adults as a baseline for feeling secure. Where this exists, I don't think you can point to any one factor to explain a lack of feeling secure - it is likely more complex.
So, as a woman who may never have my own children, I've decided against egg donation, and I dislike how it is pushed as the obvious next option by a highly profitable industry.
That said, the implication of this is that I will not raise a child from infancy. Adoption of young children - or even older children - domestic or international - is almost non-existent in many countries now, for very good reasons.
I support those who argue against egg donation, but they should not make comments about people needing to 'grow as a human' and adopt a child. It is, simply, not an option.
Sadly, many people who oppose surrogacy and egg donation appear to have zero empathy for those who are unable to conceive. And this is not going to do much to further their cause.
I should also say that I became pregnant a fortnight after posting this in desperation. Then I lost that pregnancy a few months later. It is a difficult time.
