I think that's absolutely true Wobbles. No-one ever thinks that they will be infertile.
I don't think I ever thought that my relationship was incomplete without children, I think that would be a rather sad reflection on your relationship. At the end of the day, once they've left home it's just the two of you again and you need to be comfortable with each other as a couple.
My problem with the whole infertility thing seemed to hang round me questionning what my purpose in life actually was and why was I there. I felt that I was destined to become a mother and to then find I wasn't able to (or rather that there was a good possibility that I would never become a mother) shook me to my core. Even with all the counselling I had, we never quite worked that point through to a conclusion. All the things that people say like "oh well, without children you'll be able to have a great house, nice car, fancy holidays..." well, yeah, but that all seemed rather shallow and pointless.
As for the NHS, I think the biggest problem in relation to infertility is the time it takes to see anyone. You are already a year or two into TTC before you seek help and then every appointment on the NHS is a 6 month wait and then a 3 year wait for IVF is crazy. Every month that goes by is damaging to your psychological health not to mention the effect of time on your fertility.
I'd like to see IVF available as a consistent service across the country with equal (and shorter) waiting times throughout, but at some point a decision needs to be made on the odds of success. I'm full of admiration for couples who are able to put themselves through it 6, 7, 8, 9 times, because it's pretty dreadful but someone needs to take a decision that it can't go on anymore.
As for self-funding, I felt pretty aggrieved as someone who had carefully saved money to allow me to take more time off work or to pay towards the baby that I was having to use this money in order to get PG in the first place. It is phenomenally expensive (over £5k in our case per go) that I would like to see some combined contribution on both parts. For instance, in other local PCTs, they fund the drugs (£800 ish) if you fund the treatment. Not so in our PCT, yet that gesture would have gone a long way for us.
