Good Morning. I was wondering if anyone may have heard about the hyperbaric chamber therapy trial to assist with thickening the endometrium to be ready to receive a FET? I have a daughter who is nearly 3 and we have been trying now for 4 months to grow the lining so we can complete a FET. So far this has been unsuccessful and my lining is only getting to around 5mm. My FS has advised that I may have had a small infection after the birth of my daughter which may have caused some damage to the lining. I also have some blood flow issues with a good supply of blood not reaching the lining. I have not responded well to HRT to try and grow the lining. Has anyone else had this issue and how did you try get the lining to respond. My FS has told me about the hyperbaric chamber therapy which from what I have read has had good results in getting the lining to respond. I am also on other meds to help with blood flow. My only other option if this fails is surrogacy and I don't feel I would cope down this path. Any help or ideas would be appreciated. Thanks in advance.
