I would just caution you that acupuncture is not "one-size-fits-all." A westerner who recently graduated from TCM school is not going to give you the same results as someone who went to school in China or Japan 35 years ago and who's been in practice ever since. Key things to look for:
*evidence of lots and lots of experience with fertility-related TCM
*evidence of continuing ed in non-new-age healing methodologies
*do they look you in the eye, take your pulse, ask questions, take time EVERY TIME you go?
*do they needle you in the exact same places every time? If so, they're not really paying attention and you won't get optimal results.
*do they give you new herbs every few sessions, after really examining you both before and after needling?
*do they ask you to make appropriate, if unusual, lifestyle changes, such as what you eat, drink, do for exercise? Can they "catch" you if you cheat, when they take your pulse and look at your tongue?
*is there someone else there they consult with about your case?
*are they mentoring someone or teaching at the local TCM college?
I've gone to a lot of so-so acupuncturists, and now I have The Perfect Acupuncturist - she teaches ob/gyn at the local TCM college, her husband is an MD at the local medical teaching college, and she is totally present all the time, but not in a flaky, obnoxious way. I got knocked up, stayed knocked up and healthy and happy, delivered naturally, and got my hormones straightened out after pregnancy with her help. I'm 39, and if we try again, I'm totally using her again.
If you're not wowed by the results you get after three or four sessions, go someplace else. (It will take 3-4 sessions to get a real feel for what's working or not working.) TCM is generally not covered by insurance and it's too expensive not to get the results the best acupuncturist can deliver.
