The fact that IVF transfer always fails to implant may be related to poor embryo quality, abnormal uterine environment, endocrine abnormality, low immunity and other reasons. 1. Poor embryo quality: if the embryo itself has abnormalities or the woman is older, the quality of the eggs will also decline, so the embryo will not easily implant after IVF. 2. Abnormal uterine environment: If the mother’s uterine environment is abnormal, such as thin endometrium and cervical adhesion, the embryo will not be easy to implant. 3. Endocrine abnormalities: If the mother has luteal insufficiency or thyroid disease, it will also cause the embryo not to be easy to implant. 4. Low immune system: If the mother’s immunity is low and there is abnormality of blood clotting function, it will also easily lead to the embryo not implanting. As you can see, there are many reasons why IVF transfer does not always lead to implantation. At this time, you should actively seek medical treatment to find out the cause of the disease, and then adjust the condition under the guidance of the doctor. Women who are preparing for the transplant should quit smoking and drinking, develop good living habits, maintain good health, avoid prolonged exposure to radiation or pollution, get out of the toxic and harmful work environment, and maintain a happy mood.
