Can acupuncture help in fertility treatments?

Yes. Yes, acupuncture before and after embryo transfer has been shown to help with fertility. At other times it serves as a good stress reduction method.
Uncertain benefit. Acupuncture for fertility is not supported by great evidence. One study performed in seattle had lower pregnancy rates in acupuncture group doing ivf compared to no acupuncture group http://bbc.In/hq1my7. Hard to do controlled trials: what's the placebo (fake treatment) group - needles in 'wrong places' or needles that retract? (still get acupressure not acupuncture). Chinese herbs not recommended.
Maybe, maybe not. There has been great interest recently in acupuncture as an adjunct for fertility treatments. The evidence I'm afraid is slim, with a few small studies showing an improvement and most showing no difference. So, the verdict is really still out but it seems likely that if acupuncture helps at all, it is probably only a very small difference.
WHO category. The world health organization has categorized inferlity under "diseases, symptoms or conditions for which the therapeutic effect of acupuncture has been shown but for which further proof is needed".
