Réceptivité endométriale (ERA)

Qu'est-ce qu'un test de réceptivité endométriale (ERA) ?

Un test de réceptivité endométriale (ERA) est un test au niveau moléculaire utilisé pour déterminer le moment optimal du traitement à la progestérone pour un transfert d'embryon. Une ERE peut être proposée de manière facultative (par exemple, dans les cas où le nombre d'embryons est faible), dans les situations où un transfert d'embryon antérieur n'a pas fonctionné, ou pour d'autres raisons.

An ERA involves preparing the uterus using a combination of estrogen and progesterone, in an attempt to mimic the conditions for the actual embryo transfer as closely as possible. Typically, 5 days after initiating treatment with progesterone, an in office endometrial biopsy is performed. This involves a speculum exam (similar to a pap smear), with placement of a catheter (a thin straw) through the cervix and into the uterine cavity, in order to obtain a sample of the uterine lining (endometrial biopsy). RNA is then extracted from the endometrial biopsy, and a gene expression profile analysis (a study of which genes are turned on and off) is performed on the sample. This profile is then compared to a bank of reference profiles, and used to make adjustments to obtain the optimal timing of embryo transfer after progesterone administration start.  

Ce test confirme le meilleur moment pour la fenêtre d'implantation de l'embryon de l'embryon.
