saladbomb It may be your DH sperm quality thats the issue, but if its not I can tell you what I was told. When DH and I had our appointment it was precisely to explore options in between 'doing nothing' and 'ivf'. Our consultant also recommeneded we save our money and go straight to IVF, OR just carry on doing nothing.
The reason why: ERI did a HUGE study (he emphasised it was very big of its kind) which he went through in detail. The gist was it was based on a large number of women classed with 'unexplained fertility'.
One third were told to go off and keep trying for six months, the other third were given fertility drugs, and the final third had IUI.
He said the final outcome showed that there wasn't a significant difference between the three groups, the pregnancies were more or less the same for all groups. He explained why they did it: i.e. they assumed at the beginning that IUI would give sperm a headstart, so should yield slightly more pgs; and drugs force ovaries to produce more eggs, so more chance of one sticking. That didn't prove true in the final results though.
Consultant said the other thing they found though is the different levels of 'satisfaction among women with a high level of dissatisfaction from women who were told to 'do nothing'
.
So his best advice, was go away and do nothing for a while OR go straight to IVF - that there wasn't a step in between these that increased odds for 'unexplained infertility'. There's nothing to stop us trying privately, but he said it would be better to save for IVF which DOES have increased odds over IUI and fertility drugs.
It doesn't mean IUI WON'T work for you (they did get some pgs in the study) just that the average odds are that 'doing nothing' and 'IUI' are six of one and half a dozen of the other (my terms, not his).
I've started to think of IUI and fertility drugs as remedies for specific indentifiable conditions. If you have PCOS, it might be different. Or low sperm quality perhaps (but I would have thought they'd recommend ICSI then ... because surely odds of successful IUI with low sperm is even worse than for normal folk as per study...?). But for 'unexplained infertility', it's different. But ask your consultant to spell it out for you in relation to your specific results.
What I did come away with, after holding my consultant back for ages with LOTS of technical questions and delving into studies, is what an unknown field it is and how much they can't 100% explain. The consultants accept the 'randomness' of it in a way we can't, because we feel desperate and 'doing something' takes away that helplessness, but some of what we end up doing is probably just a placebo, and good results might have happned anyway just because that's what nature is like.
My feeling for DH and I now is that it probably will happen, and I found the 'science' weirdly reassuring and confidence building, so we're giving it another six months more (approx) before we go straight to IVF.
Sorry - that was a bit long, but I hope it helps.
