RCT to Assess the Clinical Benefit of the ERA Test in Infertile Women at Their First IVF/ICSI Cycle

Plain-language summary
Endometrial receptivity takes place in a self-limited period of time during the endometrial mid-secretory stage. This period, named as window of implantation (WOI), is modulated by molecular changes allowing embryo implantation to take place.
It has been already demonstrated the existence of transcriptomic profiles that are characteristics of each endometrial phase: pre-receptive, receptive and post-receptive. 'Igenomix' group developed a molecular tool able to classify the endometrium based on its transcriptomic profile, the Endometrial Receptivity Analysis (ERA). This molecular tool analyses, by next generation sequencing (NGS), the expression of 248 genes related to implantation coupled to a computational predictor to identify the specific transcriptomic profile for each endometrial stage. This test has been applied at clinical level from 2010, helping to synchronize a viable embryo with a receptive endometrium through the personalized embryo transfer (pET). It aims to improve clinical implantation by personalizing, diagnosing, and synchronizing the endometrial factor.
Our goal in this project is to investigate at what extent, if any, the analysis of the endometrial factor, at receptivity level, in patients at their first in vitro fertilization (IVF) cycle improves their clinical outcome through a personalized embryo transfer by the ERA test in comparison to embryo transfer(FET).

Inclusion criteria:
* Patients whose written ICF approved by the EC has been obtained, after having been duly informed of the nature of the study and voluntarily accepted to participate after being fully aware of the potential risks, benefits and any discomfort involved.
* Patients undergoing their first IVF/ICSI cycle (first oocyte pick up, freezing all) with their own oocytes that will receive single embryo transfer of frozen blastocyst stage embryos (day 5/6) on an HRT cycle.
* At least 2 morphologically good quality embryos already vitrified in blastocyst stage (day 5/6).
* Maternal Age: ≤37 years to rule out embryo factor in aging patients.
* BMI: 18.5 - 30.0 kg / m2 (both inclusive).
* Normal ovarian reserve (defined as: AFC ≥ 8; AMH level ≥1.0 ng/ml and/or FSH \< 8 mU/ml) before the controlled ovarian stimulation (COS) initiation.
* Serum P levels ≤ 1.5 ng/ml, measured within 24 hours before the hCG administration in the COS cycle.
* Negative serological tests for HIV, HBV, HCV, RPR.
Exclusion criteria:
* Patients with repeated miscarriages (\> 2 previous biochemical pregnancies or \> 2 spontaneous miscarriages).
* Male partner with severe male factor (spermatozoa \< 2 million/ml). Semen donor is allowed.
* Patients who are intrauterine device (IUD) carriers in the last 3 months before sample collection.
* Adenomyosis or any pathological finding affecting the endometrial cavity such as polyps/sub-mucosal myomas, intramural myomas \> 4 cm, or hydrosalpinx must be pre…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
