The octuplets case is pretty extreme (with mental health questions involved)-- and one does need to take the view that counselling should be involved, generally, to ask why someone is so desperate to have children that they will undergo some quite risky procedures (IVF usually involves ovary stimulation, and this can cause fatal reactions)...but hey, as long as they aren't expecting to be supported by the taxpayer, none of my business either way.
In the UK, of course, it IS my business as a taxpayer, since some IVF is done on the NHS, plus any resulting kid gets taxpayer-funded health, education, tax credits, family allowance payments, child trust fund payments, etc.
So unfortunately, it's HER body, MY money.
