Honestly, I don't think IVF is really a comparable alternative to adoption. Not in this country, at least.
With IVF, you are still conceiving and birthing a baby that is usually genetically related to the two of you (so you are aware of their medical and social history) and they are with you from day 1 (hopefully). You are raising a child who is genetically yours, and hasn't experienced the trauma of abuse or separation. Both of which are often relevant with adopted children.
Adoption is taking a child who very likely has a known social history of a troubled familial background plus genetic and congenital tendencies for mental illness, neurodiversity and behavioural issues. You likely won't meet them early on and won't be raising them from birth. Their known history is likely to only be part of their full story.
In my personal opinion, adoption and fostering shouldn't be "advertised" as a way of helping people with fertility issues become parents. The motivation for the adoptive parents should be something other than merely fulfilling their desire to raise children as their own because it isn't the same as conceiving and raising your biological children.
I think as adopted children are more able to know who their biological families are and are more able to independently contact them and have contact with siblings etc, we can't keep treating adoption as the same as biological parenthood. It's a different realm.
This isnt anything to do with how you can feel about your adopted family/child or how much you can love them or whether you can love them as much as bio family. Of course you can, but the part of their life that comes from their biological ties can't be ignored and in fact, has to be part of your conversation with them as soon as they can converse with you.
I think egg and sperm donation and in another way, surrogacy are slightly different and are comparable to conceiving and birthing your own baby. Although you may not be genetically related or in the case of surrogacy, carried the baby, but you are usually more aware of their background and with surrogacy, are there from day 1 in the way that was preplanned.
