I did some research years ago and the WHO actually recommends/supports the use of acupuncture to treat - yes treat - some thousands of conditions.

You have to realise that traditional chinese medicine has been around for so very very long, much longer than modern medicine, and is 'competition' for modern medicine which is another reason why GPs may not recommend them. On the other hand I also know some GP acupuncturists also.
This is so true.... There is bucket loads of evidence that points towards the benefits of acupuncture during IVF and TTC. Perhaps ask your practitioner for some studies (he or she will probably have access to some reputable ones) and take them to your doctor. Sometimes GP's tend to not accept alternative therapies simply because they know nothing about it.
