This is a bad place for an ivf discussion - anyone wanting some help and guidance should move over the 'becoming a parent' infertility thread.
There are many misconceptions about ivf and ignorance of the facts - that's why professional bodies such as NICE make the decisions rather than relying on results to a public opinion poll.
I'm five months pregnant after a mix of nhs and self funded treatment. Yes, it is possible to do this in tandem combining cycles and buying some of your own drugs. Access to ivf is tightly controlled and there is a huge lead up to it that will take years as other routes (yes, there are other fertility treatments) and solutions are explored. Not only that, your suitability to parent will be assessed despite what coronation street may depict.
My private cycle cost 5k. It was provided in the same hospital where my nhs treatment took place. By my reckoning (and comments from fertility expert Prof winston) this was about a 2k mark up. I attended the largest unit in Europe. It is in essence an efficient production line serving a substantial section of the uk. The point is that, relative to other procedures and medication, a round of ivf may not be as costly to the nhs as popular opinion thinks.
For those calling for priorities to be made you might want to think more broadly. As someone said up thread, an epidural isn't a medical necessity in childbirth, nor is gas and air for that matter. Im hesitating before typing this as i'm not suggesting it for one second, but breast reconstruction post masectomy isnt necessary either. The point is that there are many medications and procedures that are not necessary to sustain human life but are paid for by the nhs. in terms of efficacy too, it is erroneous to assume that all procedures are 100% efficacious and that 100% of medication is effective. To the person up thread whose grandad needs a knee replacement - they are not guaranteed either (my own parent is testament to that) so you might want to balance that in too.
Infertility is a struggle on a day to day basis precisely because of the opinions against it expressed here. You don't talk about it because people are ignorant and judgemental. Society is family oriented - there is a reason why being pregnant is called 'being in the club'. Apart from a fundamental natural desire to be a parent, non-parents will be judged by many as 'selfish' excluded from conversations and feel marginalised in society. That's my experience based on my infertility and now my pregnancy.
On adoption - well where to start? So many misconceptions. Adoption is about finding parents for children NOT finding children for would be parents. Yes - there is a difference. Children in need of adoption often have special needs best met by those with experience of parenting. Being infertile does not qualify you to parent challemging children. Added to that, agencies require a 'cool off' period between fertility treatment and starting the adoption process. This can be any thing up to two years. Given that most people spend years investigating infertility it's a very long road and one that requires you to shut off the option of conceiving your own child before knowing if you would be considered suitable to adopt any child.
So frankly I do not feel guilty at accepting nhs help to conceive my one and only child. I do not accept that I have denied a child a hearing aid or ripped the iv from the arm of a cancer patient any more than a substance abuser or nhs health tourist has.
