implantation failure

Implantation failure occurs when a fertilized egg (embryo) does not attach properly to the lining of the uterus. This is a crucial step for pregnancy, as the embryo needs to implant securely to receive nutrients and grow. Various factors can contribute to this failure, including issues with the embryo's quality, problems with the uterine lining, hormonal imbalances, or underlying health conditions. It can happen after assisted reproductive technologies like IVF or even during natural conception. Understanding and addressing the underlying causes can help improve the chances of successful implantation and pregnancy.
