About this trial
Analysis of proteins from cervical mucus will be done in patients undergoing infertility treatment (fresh or frozen embryo transfer). Cervical mucus will be analysed for potential new biomarkers of endometrium receptivity. Comparison of the peptide spectrum will be done for the pregnant and not pregnant patients.

Treatments tested in this trial
Cervical mucus will be collected from patients undergoing IVF

Treatment groups
Trial outcomes
Primary outcomes
Mass spectrometer analysis of the proteins from cervical mucus
Highly sensitive mass analysis of the proteins from cervical mucus on Thermo Orbitrap Elite instrument for all collected samples.
Secondary outcomes
Comparison of the protein analysis between the pregnant and not pregnant patients
Comparison of the protein analysis (qualitative and quantitative) will be done between the pregnant and not pregnant patients. Pregnant patients will be followed-up until child delivery.
Detection of the new endometrial receptivity biomarkers.
Proteomic endometrial receptivity biomarkers will be detected based on the analysis of measured data in relation to the successful implantation.
