Hi and thank you for your enquiry. There are no concerns at all about IUD's and BFST. Our BFST products are Class II medical devices and are designed with so much intrinsic safety that they can be used in hospitals without concern for interference with any sensitive medical equipment even when the BFST and other medical equipment are being used at the same time on the same individual.
We would definitely be interested and curious to see the FDA report but can imagine that the concern stated would be around induced electric currents being created in the copper of the IUD by very low frequency devices which produce magnetic fields. This is not at all a concern for our product.
I hope this has answered your question. If you have any further questions or concerns, please do not hesitate to contact us.
Kind regards,
Amber
