I'm disappointed to see this debate rumbling on with some of the same hypocritical and misinformed views that I'm sure were responded to several pages ago.
A biological family is a luxury not a right. That isn't the consideration here (athough for what it is worth, it's bullshit!) the real question is, do women have a right to have their recognised medical condition (infertility) treated on the NHS in order to assist them in creating a family? I don't see how the answer can be anything other than yes. Recognised medical condition with a treatment that has been deemed to be cost effective using the same criteria that all other treatments are assessed by. All this talk of low success rates is also not true - no IVF doesn't guarantee a baby, but over three cycles the results are very good. I can't find the exact reference but one Danish study found that somewhere in the region of 70% of women going through treatment eventually had a child. That's not bad - it beats some cancer survival rates. Pound for pound, it has been considered to improve quality of life sufficiently to be vaiable as a treatment. Success rates are only one part of the equation, needing to try is also important.
If your child is a 'luxury item' then perhaps you wouldn't mind paying a higher rate tax to fund this luxury lifestyle of yours that us infertile women can only dream of. Means testing maternity benefits, removing child tax credits - it can't be a luxury for one part of the population and not another!
Delphine, you completely neglect the quality of life concerns of the infertile woman (and her partner). Do you not think that is equally important? It affects those involved as much as other serious illness do, and they have a right not to suffer.
