Where do you draw the line? I don't know the answer. It's very difficult. But I get annoyed when IVF is targeted as a "luxury". It's far from a luxury for those who need it.
I really can't imagine what it is like to want a child when you are infertile and I wish the NHS could afford to give everyone who needs it IVF.
My ex husband's wife was turned down because she was a step mum to my children. They live with me and her being a step mum did not take away from her heartbreak. He was infertile due to cancer treatments. She found it incredibly unfair, and the current way it works, who gets it and who doesn't is unfair.
To the people saying having children is a choice, not a right - does that mean the NHS also shouldn't fund maternity services? You choose to be pregnant, you should pay for your own childbirth??
It's not really the same is it? Once you are pregnant you need maternity services for your health. The baby needs to be delivered safely. It's different to helping people conceive a child.
We could say that about anything. If you choose to play sports don't ask for free treatment if you hurt yourself. Drive a car and crash? Well, your choice to drive! Looking after the health of mum and foetus/baby is different to funding the conception.
