Low Ovarian Reserve

I have a patient going on her 5 attempt at an IUI. She had been taking clomide, but will now be attempting the IUI with Letrozol. This will be the second IUI back to back. Does anyone have any good information on a formula or protocol to help her body deal with the stress and aid in conception. She seems like a classic Kidney deficiency, I'm just not sure she is allowing enough time between IUI's to have Acupuncture play a significant role.
