Endometrial Genomic Profile in Endometrial Priming

Profile Study of Genomics Endometrial Expression After Gonadotropin-releasing Hormone Agonist Administration and GnRH in Endometrial Priming.

The aim of this study is to analyse genomics profile expression in endometrium under different endometrial priming for recipients.

We analyze the genomic profile of egg donors in different endometrial priming protocols, compared with natural cycle, including the conventional single long acting GnRH agonist injection in the mid luteal phase of the previous cycle of the endometrial priming and the single daily antagonist injection (Cetrorelix 0.25 mg) administered in the early follicular phase followed by endometrial priming. Endometrial biopsy will be taken in luteinizing hormone
