If the number of diarrhea after IVF transplantation is small, it will not affect the implantation; if the number of diarrhea is more frequent and severe, it may have an effect on the implantation. Diarrhea can be caused if there is stress after IVF transfer, if the diet is not reasonable, or if it is cold. If the number of diarrhea is small, it usually does not affect the embryo implantation; if the number of diarrhea is large and abdominal pain occurs, then it is likely to affect the embryo implantation. At the same time, severe diarrhea can also cause electrolyte disorders, malnutrition, these adverse factors will affect the embryo implantation. Therefore, severe diarrhea should be treated according to the specific condition and cause of the diarrhea under the guidance of the doctor. As we can see, we should avoid excessive stress after the implantation, eat a reasonable diet, and avoid getting cold, so as to avoid diarrhea and other symptoms that may affect the implantation of the embryo.
