Hi OneDay, I had acupuncture and TCM from three different practitioners during my IUIs/IVFs and I didn't fall pregnant. The third practitioner I saw was a very well-regarded Chinese doctor (before she came to Australia, she was a specialist TMC-gyno in a hospital in Beijing) and, though I did have a laparoscopy removing endo just prior, I fell pregnant (naturally) about 6 months after seeing her.
Everyone is different of course, and there's no set path.
But from my experience (and I am a bit older, 33), I think healthy diet (low GI, high protein and eliminating any possible intolerances like wheat and yeast, and excess sugar especially because it totally affects hormones) and TCM do have a place to assist alongside the more scientific treatments (IVF). But in my case, I think whilst TCM did help, I think it was the lap which must have had an impact. I had moderate endo and virtually NO symptoms. Have you had a lap? I really think that when you've been trying for ages, and you're "unexplained" (esp if your partner has really good stats) that a lap should be par for the course.
Also, check out this TCM guy: what is his rep? How many other ladies has he helped?
Best of luck and FX for next cycle!
