I had acupuncture for about 10 months before first IVF, in an attempt to help with spotting before periods and help fertility. I think it was weekly for about 6 weeks then every 3 or 4 weeks. DH had some sessions at the start too. Then more targeted sessions in the lead up to IVF but the cycle got cancelled due to poor response to stims.
I didn't go back to that acupuncturist but went to a different one shortly afterwards and had 2 sessions on transfer day, before and after the procedure.
The IVF didn't work out.
I feel much like @Iwouldbecomplex it was a lot of money for no tangible benefit. I didn't find it relaxing apart from one particular session with the second acupuncturist where I felt a lot of tension leave me. But mostly it was a faff fitting in appointments around work.
I had acupuncture many years ago for something else so reasonably open to it as an option but didn't use it again for any further IVF.
I think there are too many variables for anyone to be confident that it "works" or was the thing that made a difference on any particular cycle but it made me feel like I was doing something.
The NICE guidelines are for 3 cycles of IVF on the NHS because it's not expected to work every time. If you don't have acupuncture for one cycle and do have it next time and it works, is it the acupuncture, or the fact that your clinic learned from previous treatment and tweaked your meds, or your ubiquinol, or the fact that you ate pineapple core or drank beetroot juice or just luck because it's a numbers game.
