Acupuncture for IVF Revisited – More Tooth Fairy Science?

I read this Reuters Health article on MedlinePlus, and then I read the study the article referred to (The impact of acupuncture on in vitro fertilization) and now my head hurts. The study found that acupuncture was not effective in increasing the pregnancy rate (PR) during in vitro fertilization (IVF). As quoted on MedlinePlus, the lead author, Alice Domar, seems to blame her patients (the presumably poor quality of their embryos) rather than acupuncture for the lack of success, and then she recommends using acupuncture even if it doesn’t work. That was bad enough, but “poor quality embryos” is a hypothesis that was actually tested and rejected in the study itself. Has Domar forgotten?

The headline of the MedlinePlus article says “acupuncture doesn’t boost IVF success for all” – suggesting that it boosts success for some? Then the first sentence says the study suggested that acupuncture doesn’t work, period. But wait…

The lead researcher says acupuncture may not have worked in her study because, unlike past research, her investigation wasn’t limited to women who had good quality embryos available for transfer. “I’m wondering if my sample was just not a good sample, in that most of the patients in my study were probably not the best-prognosis patients,”
Domar and her team say the most likely explanation for the lack of an acupuncture effect in their study was the fact that they included many women who didn’t have good quality embryos available for transfer. While acupuncture may help a woman become pregnant after the transfer of a healthy embryo, the researcher noted in an interview, it can’t repair an embryo with chromosomal defects or other abnormalities.

Hold the boat!! In the Discussion section of the paper itself, Domar et al point out that previous research has included mostly patients with good quality embryos. They ask if perhaps acupuncture only works for good quality embryos? They test that hypothesis by separately analyzing the subjects in this study who had good quality embryos. There was no increase in PR with acupuncture in this sub-group; the results were the same as for the entire sample. (more…)
