What are the methods of evaluating endometrial receptivity?

In IVF treatment even the best quality embryos fail to implant. Receptivity of endometrium is important in controlling implantation. Both invasive and non invasive methods are available to evaluate endometrium.

• Non invasive methods: Ultrasound on endometrium to detect thickness, pattern and sub endometrial blood flow. 3D ultrasound for calculating endometrial volume
• Invasive method: endometrial receptivity array

Timeline of Implantation process

Successful implantation of the embryo is the rate limiting factor in IVF treatment. This process includes following steps:

• • Implantation process starts on day 5 post fertilization and probably ends on day 10 called implantation window. At this time we can confirm pregnancy with beta HCG test in the blood.
  • The zona pellucida surrounding the blastocyst ruptures on day 4 post fertilisation.
  • This phenomenon is also known as hatching.
  • Adhesion of the blastocyst to the endometrium is the next most important step.
  • The embryo starts developing and burying into the endometrium in the next few days.
