Compare the endometrium of oocyte donors, who had final oocyte maturation with either hCG, Suprefact, followed by hCG 35 hours after triggering, Suprefact or Suprefact without luteal phase support. Group A, B, C receive luteal phase support for 5 days, until the day of endometrial sampling (OPU+5). To avoid inter-patient variation in endometrial histology, each patient will preferably perform 4 consecutive oocyte donation cycles, within one year, using models A-D for final oocyte maturation

| Main Objective: comparison of endometrial status after different types of final oocyte maturation;Secondary Objective: ;Primary end point(s): Study groups A, B, C and D: Histological markers (Noyes criteria) in all samples as well as gene expression in a subset of each group. A set of classical implantation markers can be added, ie osteopontin, glycodelinA, Dickkopf, transcobalamin, dipeptidilpeptidase IV. Differentially expressed genes in the three groups can be further explored and compared to already known implantation factors. Progesterone-receptor, LH-receptor expression and oestradiol-receptor expression, possibly performed with quantitative RT-PCR in relation to two or three house-hold genes constantly expressed. Further analysis of gene expression with the Affymetrix HGU133Plus2 microarray. According to previous publications, the significantly up and down regulated genes will be analysed (SERPINB6, FOXO3A, SOX17, and CDC42, NRP1, HOXA10, and OSF2). | — |
