Brief Summary
Do differences in endometrial gene expression exist after different protocols of endometrial preparation for embryo transfer? The recent apparition of endometrial receptive arrays technology let us know if endometrial is receptive or not in patients with some problems of infertility as implantation failure, for that we want to know if this technology would tell us if the different kind of protocols for endometrial preparation origin differences that could explain some of the founded results.

Outcome Measures
Primary Outcomes (1)
Endometrial receptivity
Total RNA was extracted using the TRIzol method according to the manufacturer's recommendations (Life Technologies). Approximately 1-2 mg of total RNA was obtained per milligram of endometrial tissue. The RNA quality was assessed by loading 300 ng of total RNA onto an RNA LabChip and was analyzed in an A2100 Bioanalyzer (Agilent Technologies). Only samples with a RNA integrity number \>7 were selected for microarray analysis. Sample preparation and hybridization was adapted from the Agilent technical manual. Hybridized microarrays were scanned in an Axon 4100A scanner (Molecular Devices), and the data were extracted with the GenePix Pro 6.0 software (Molecular Devices). The ERA microarray validation has been previously published. Reverse transcriptase-polymerase chain reaction (PCR) was performed for four selected up-regulated genes: GPX3, FXYD2, SPP1, and MT1G. The ERA gene expression values were preprocessed, normalized, and statistically analyzed. Briefly, the half background

pilot study
A total of 5 volunteers from our egg donation program were included in the study with 4 endometrial biopsies for each one after 4 diferente protocols * Endometrial biopsy after Stimulated cycle * Endometrial biopsy after Natural Cycle * Endometrial biopsy after Natural modified cycle: the biopsy is taken seven days after the hCG * Endometrial biopsy after Hormone Replacement Therapy Cycle
