Implantation Failure

 

Introduction

Implantation failure can be divided into three areas.

  1. Problems with the embryos
  2. Problems with “host” uterus
  3. Problems in the interaction between embryo and uterus.

Failure to achieve a pregnancy following 2-3 IVF cycles in which reasonably good [ high grade embryos] embryos were transferred is termed as implantation failure.
Embryonic loss which occurs repeatedly after Assisted Reproduction may be attributed to many factors.

These are grouped into three categories :

  1. Decreased endometrial receptivity
  2. Embryonic defect
  3. Factors with combined effect
