Overview
Brief Summary
The objective of the study is to gain a better understanding of the gene expression changes in the endometrial biopsy especially whether the endometrium has reached a receptive status, i.e. the implantation window, or not.
Detailed Description
The endometrium goes through huge gene expression changes during a cycle, the cells are transformed, the mucous membrane thickens, then loosens, and finally sheds. In this process, the expression of the genes also goes through significant changes, which can be determined from a small tissue sample. Endometrium biopsy samples can be used for endometrium phasing. A question of the study is the feasibility of using for endometrium phasing beside endometrium tissue biopsy also samples generated by endometrium lavage. The advantage of this latter method is that it is minimally invasive, it does not cause haemorrhage and has minimal side effects. In some selected cases endometrial lavage will be performed on the same day with endometrial tissue sampling together with the drawing of a peripheral blood sample. A list of potential biomarkers was proposed from the meta-analysis of published gene expression datasets. From the endometrium derived samples, RNA will be isolated and gene expression biomarkers will be measured. Expression profiles will be compared to published reference samples.

Outcomes
Primary Outcomes
endometrium phase assesment
Time Frame: phase assignment is performed within two weeks after the measurements are performed.
based on the gene expression profile endometrium samples are phase assigned based on published reference samples
gene expression profile
Time Frame: measurements are performed within 3 weeks after samples are shipped to the laboratory
the endometrium derived samples are measured for the mRNA level expression of a selected list of biomarkers as it follows: ABCC3, ACTB, ADAMTS2, ADAMTS8, ARG2, ASPN, B2M, BAMBI, C10orf10, C1QTNF6, C2CD4A, CCDC71L, CD55, CEBPD, CP, CRISP3, CTHRC1, CYP24A1, CSRP2, DDX52, DPP4, DUOX1, DUOXA1, EDNRB, FCER1G, G0S2, GADD45G, GNG2, GNG4, GPX3, GRAMD1C, GREM2, GZMA, HPGD, HTR2B, IGFBP1, IGFBP3, IGFBP6, IL1B, IRX3, ITGA2, ITGB6, KAL1, KCND2, KCNK3, LCP2, LEFTY2, LRP4, LTBP2, LUM, MAOA, MAP2K6, MFSD4, MMP10, MS4A7, MT1M, MUC16, NID2, NNMT, OPRK1, PAEP, PDE4B, PHLDB2, PKHD1L1, PLAT, PLD1, POLR2A, PPIA, RARRES1, RDH10, RGS1, RHOB, RHPN2, RIMKLB, SGIP1, SLAIN1, SLC15A1, SLC15A2, SLC1A1, SLC26A7, SLC5A3, SOD2, SPP1, SYT11, TBP, TCN1, TFPI2, THBS1, TIMP3, TMC5, TMED6, TNFRSF11B, TSPAN8
