After the failure of blastocyst transfer, the time for another IVF embryo transfer varies from person to person and needs to be decided under the guidance of the doctor. And it is only after the woman’s body recovers that the success of blastocyst transfer is favored. If there is a history of blastocyst transfer failure, it is recommended that the causes of transfer failure should be discussed with the doctor before re-transfer, to find out whether there are any diseases such as hydrosalpinx of fallopian tubes, endometrial polyps and other anatomical abnormalities such as endometrial thinning that lead to the failure of the transfer, and whether there are any immune problems such as antiphospholipid syndrome and coagulation abnormality that lead to the failure of the transfer, and then target treatment for these causes of the disease. It is recommended that the thickness of the endometrium be approximately 8mm or more before the transplantation, and that women should maintain a good state of mind, with appropriate daily activities, a balanced diet, and avoidance of anxiety and tension. If there are abnormalities such as vaginal bleeding, abdominal pain and other symptoms after blastocyst implantation, it is recommended to consult a doctor in time, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
