I would also question why you would go with IVF instead of adoption since you already looked into fostering - and therefore presumably see parenting as raising a child and not creating a human who shares your DNA.
Most people just have no idea what adoption involves.
Adoption is an expensive and emotionally tumultuous experience. It is not for the faint of heart. Every kind of adoption has issues: domestic infant adoption is the only way to get a baby, and you have to compete
heavily against other couples (many whom have been waiting for years) and still have no idea what the mother may have ingested or injected along the way. International adoption is different for every country, but it is difficult to get a young healthy child, impossible to get an infant, and you have the other issues of not knowing the child's history. It also costs more, since you have to travel to the child's country of origin, sometimes for weeks at a time, to complete interviews and paperwork, and then go back
again to get the child.
It is a huge misconception that there are plenty of healthy babies just waiting for a loving home. There are TONS of kids who need adopted, but they are all older, and many (most?) have special needs. There is a strong need for people who can be parents for them, but I am not ready for an older or special needs child. We are keeping that open as an option after we get some "parenting experience", though. As newbie parents, we are just not prepared for that.
Not sure what you mean by seeing IVF as similar to "bling". Do you just mean expensive? Adoption and IVF are almost exactly the same price. Actually, if you were successful on your first IVF attempt it would be cheaper. Kids are always a luxury, and even more so when you can't make them naturally.
It is not uncommon for someone who has not experienced infertility to have certain judgments about IVF treatments. I had them myself before I went through what I have, and most people think adoption is easier than it really is. All I can say is that it is a medical condition that I intend to seek treatment for, no differently than I would for a myopia or cancer. I don't think people who get sick were "meant to" die, or near-sighted people were "meant to" see poorly, and I don't think infertile couples were "meant to" adopt.
I am not against adoption, but before I go compete for a baby with couples that legitimately cannot conceive on their own (whereas, I can with medical assistance), I don't see any reason not to first try IVF. Why take a baby from other loving couples?
