Normally, the hormonal changes in the body on day 7 of blastocyst transfer are not yet significant enough to be measured for the time being.
Blastocyst transfer is part of IVF, which involves transferring a fertilized egg inside a woman’s uterus. Generally, hormone levels need to be measured about 2 weeks after the transfer to determine the changes in blood HCG as well as sex hormone six, etc. If the HCG level is doubled, it means that the transfer has been successful, and the measurement on the 7th day is not accurate enough to get a clear result.
After blastocyst transfer, women need to take rest, relax, and carry out fertility preservation treatment to promote the success of embryo transfer. In the time of 2 weeks after the transfer to the hospital in a timely manner, please ask a professional doctor based on the results of the examination to determine the status of the transfer.
