Aldingen some additional information I forgot in my initial question:
– no problems with uterine thickness and according to my doctor no signs of any scarves as due to thickness of approx 9-10 mm few days before ovulation
– during the biopsy for endometritis nk cell from uterine will also be tested.
Would you suggest any another testing in regards to hashimoto? Or anything else?
As said, I have DOR and advanced maternal age, but the eggs retrieved always looks good. As we experience secondary infertility for some years now, there seems to be an additional underlying problem
