IFCE-Intrauterine Fiberscope & Curettage of the Endometrium

 

IFCE Technique

 

  ET (Embryo Transfer) Technique

The IFCE technique is just an endometrial biopsy, and advanced technology is also required for an ET.

 

At our clinic we have considered the following, (2009 · 13th World Congress on Human Reproduction, "The impact of endometrial thickness, technical ET catheter issues and day 14 serum HCG after ovum pick up on the implantation rate and pregnancy outcome. At the 29th Annual Fertilization and Implantation Conference in 2011, the Society recognized "The thickness of the endometrium, the type of bleeding and the catheter at the time of embryo transfer will affect the results of IVF"), ET's at the time, used the hard catheter, the blood on the tip of the ET catheter was found to give poor implantation rate. This is when the endometrium, which had growth in IFCE up to the previous period, and is damaged by the ET catheter, it is not considered to be due to the deterioration of the implantation environment.  In other words, IFCE is effective only when when transferring the embryo to the regenerated part of the endometrium without damaging that part.  Advanced ET techniques are required to avoid such damage.

 

Therefore, at our clinic, we select a catheter that is more flexible and will not hurt the endometrial lining so as not to disturb the implantation environment as much as possible and transfer the embryo, aiming at the part of the inner membrane regenerated by IFCE with a very careful approach under ultrasound.  As it is desirable to have implantation directly at that position, we are considering how to aid implantation and prepare the embryo optimally using AHA (Assisted Hatching) (1. Size of openings [apertures], position, etc., 2. Thickness, width, position, etc. of Zona thinning).
