At present the research does not show a link between IVF and cancer, as far as I understand it/am aware.
Re mental health, IVF has destroyed mine. I have always struggled with PMS, now have PMDD because it screwed my hormones.
That being said, I see no problem with IVF. Yes, embryos get destroyed. But I think there is a false understanding on this; many of those embryos would not grow to childhood in any event. I had an embryo that didn’t take (and a later loss); the only reason I knew about the one that didn’t take was because it was IVF. Many embryos at a similar stage will not make it and simply be dismissed as a period. It is not wholesale destruction of human life. That being said I am desperate to use my last frozen embryo because I can’t bear the thought of it not getting its “shot”.
I agree there is a discussion to be had around (1) NHS funded IVF; (2) surrogacy/egg donation (though I don’t really have a problem with the latter - again not aware of any actual decent research suggesting it is bad for the child).
Re “infertility being nature’s method of population control”. What utter spurious nonsense. Nature doesn’t have a control. Our infertility stemmed from an infection my husband had that was not correctly treated. It was pure bad luck that he was treated negligently. Nothing to do with nature.
I think the big problem is - as with most things - people feel entitled to have an opinion on what others do that is none of their business, and on which they have no relevant knowledge or skillset from which to comment. Fine, have an opinion on whether the State should fund treatment, but it really is none of your business what someone else is doing outside of that, irrespective of your views/beliefs on embryo destruction, population control or Gaia.
It hurts every time someone says if I can’t reproduce naturally I shouldn’t have children, that IVF children are children that shouldn’t exist, or that they are against nature. I’m incredibly short sighted. By wearing glasses am I foiling nature’s plan for me to fall off a cliff/be consumed by wild hogs/insert “appropriate natural death here” and thus control population? It’s equally plausible. So where’s the line? And why do you get to decide my line? I accept that I don’t get to decide what is ok for you so why do you get to decide for me? Even on the internet - maybe especially on the internet - it doesn’t hurt to think before you express an ill- or un-informed opinion.
