You can generally bet that the people who say that having children is not a right, or that the NHS should be paying for childhood cancers rather than helping those infertile people have a child, are not the infertile ones themselves.
From a purely personal and financial perspective, I have cost the NHS very, very little over the years, despite paying taxes from age 22. That's my good fortune and it is irrelevant. But for those saying "The NHS should not not fund IVF", it is often the case that these childless people in their 30s/early 40s have been thus far been far less of a "drain" on resources than someone with children, who naturally are the ones who the NHS spend a lot on. If you want to look at it like that. It is also usually the case that those who have been TTC for the necessary 2 to 3 years before being referred are the non-smokers and light drinkers.
I planned on starting my family at 34-ish. At nearly 38 I still don't have a child, and have been uncomfortably aware that because of delays and fuck ups with the system, my time could be running out fast.
I also agree that more should be done to get the message through that fertility declines after the mid 30s (even though for many people that is irrelevant anyway, because their problems are not age related). And by this I don't mean Daily Fail -style scaremongering, but proper education in schools. I always assumed that you were fertile until the menopause hit. It was only after starting TTC that I realised otherwise, and I am by no means an unintelligent, uninformed person.
So yes this is a good thing, though people mustn't think that the chances of IVF working at 42 are the same as at 36.
