There have been a few studies. Some suggest that it does, either on its own, or as a helpful supplement to IVF. Some REs recommend it, other, more traditional ones, think it is a waste of money. In any event, I haven't seen anything to suggest that it hurts, including my own skeptical RE!
The premise is that acupuncture helps promote blood flow and circulation, thereby improving ovarian function and with staying pregnant.
Friends of mine who have used it with success swear by it. Both natural conceptions and through IVF/IUI.
Good luck!
Does acupuncture really help you concieve?
I found that if I only tested once a day in the am, I would've missed my window so the months I'm trying naturally, I test at least twice/day. I buy a month's worth of OPK at a time. And I get the digital happy face OPK b/c I hate trying to figure out if the line is "darker or as dark as" the control line.
