Uterine causes of implantation failure

Implantation failure can be caused by uterine factors, as these can affect endometrial receptivity and, therefore, embryo implantation. Possible causes related to the uterus include:

• Chronic infections in the endometrium.
• Abnormalities in the uterine cavity.
• Displacement in the implantation window.

Therefore, the specialist must investigate these possible causes to determine whether this is the origin of the implantation failure.
