I have had two rounds of NHS IVF - luckily the second one worked. If it hadn't been available on the NHS we would've either saved up (although by the time we had more money my chances would've been lower) or looked into adoption.
Though I took the NHS route, I would understand if the government chose not to fund it. At the same time, I think there are reasons to fund it as well.
I've read the thread pretty quickly so I'm not sure if anyone's mentioned some of the scientific benefits from IVF - for example when I had mine I chose to sign forms saying that unusable eggs and embryos could go into research, such as stem cell research. There would be far fewer eggs/embryos for this valuable research without IVF.
I think it's unfair to solely focus on 'IVF isn't life-threatening and cancer is'. The NHS pays for tons of things that aren't life-threatening! I think it's important for our society to improve life as well as save lives (though I do agree that saving should have priority) and as infertility is a medical condition (save for after the menopause), I see nothing wrong with looking at ways to correct it.
Personally I have unexplained infertility. I'd rather there were more diagnostic tests to find out why exactly, but as there weren't I did IVF. But you don't jump straight to IVF. First there's simply not conceiving, then there's blood tests, sperm tests, waiting for referrals, clomid, ultrasounds, HSGs. At the end of it all you still don't have an answer and someone says 'we'll put you on the list for IVF' - by that stage many people who wouldn't have considered it at the beginning will have changed their minds.
Adoption isn't necessarily the solution. It can take years in itself, there aren't as many babies available as some imagine and older children can often be more difficult to look after due to their backgrounds. It's great if infertile people do want to adopt, but it does require a great strength of character (I admire anyone who does it) and is not for everyone. Isn't it something like one in five adoptions fail for older children?
I don't believe NHS IVF really has anything to do with women who 'wait too long' to have children - for a start there's an age limit on it! I was only 26 when we started to TTC.
Perhaps I could've accepted that it wasn't meant to be, but there are plenty of medical conditions that aren't life-threatening that could be left 'as is' and are treated on the NHS anyway.
Now as I've said, I'd understand if free IVF wasn't available, so I'm not saying it should come before live-saving treatment. But if whoever's in power chooses to put money into life-improving as well as life-saving treatments, then I think that's fair too.
I look at my four-week old now and I am so glad he's here.
