Instituto Bernabeu is presenting nine research papers at ESHRE 2026, the largest international conference on reproductive medicine, in London.

The research once again places Instituto Bernabeu amongst the centres with the strongest scientific presence at the annual congress of the European Society of Human Reproduction and Embryology (ESHRE), the most important international event in reproductive medicine. At the 2026 conference, the team will present seven scientific posters and take part in two expert panel discussions, reaffirming its commitment to the development of reproductive medicine that is increasingly precise, personalised and based on scientific evidence.

The research to be presented by Instituto Bernabeu addresses some of the key current challenges in assisted reproduction, ranging from improvements in embryo and sperm selection to the study of implantation failure, reproductive genetics, ovarian stimulation, male factor infertility and the application of artificial intelligence to optimise clinical outcomes.

Two presentations at expert panel discussions

In addition to the scientific presentations, two specialists from Instituto Bernabeu will take part as speakers on international expert panels, an honour reserved for leading researchers in their field.

Dr Jorge Ten, Director of Embryology at Instituto Bernabeu, will deliver a presentation entitled ‘Sperm selection: from conventional methods to biomimetic approaches’, in which he will analyse the evolution of sperm selection methods towards biomimetic strategies capable of replicating natural selection processes.

Meanwhile, Dr Belén Lledó, Director of IB Biotech, will be one of the speakers at the Sona-Pharm Summer School of Reproductologists, a training initiative taking place as part of ESHRE 2026. During this session, she will deliver a lecture entitled “Genetics of the ovarian response”, focusing on the role of genetics in the ovarian response and its application in the development of increasingly personalised assisted reproduction treatments.

Seven research projects selected by ESHRE

Alongside these lectures, Instituto Bernabeu will present seven poster presentations covering some of the main lines of research carried out by the group:

• Laura Cascales (Instituto Bernabeu Madrid): Biopsy timing reflects embryo biology rather than genetic competence in good-quality blastocysts.
• Dr. Paolo Cirillo: Follicular flushing does not increase oocyte yield compared with single aspiration in patients classified as POSEIDON groups 3 and 4.
• Dr. Esperanza de la Torre (Instituto Bernabeu Madrid): Endometrial compaction does not predict ongoing pregnancy after modified natural cycle euploid single-embryo transfer: a multicentre prospective cohort study.
• Paqui Lozano (IB Biotech): Analysis of structural variants identified by Optical Genome Mapping in patients with recurrent implantation failure and recurrent pregnancy loss.
• Dr. Belén Moliner: Atosiban improves implantation rates in patients with elevated uterine contractility: a counterfactual análisis at different uc thresholds.
• Dr. Ruth Morales (IB Biotech): Influence of male gamete in embryonic aneuploidy.
• Dr. José A. Ortiz (IB Biotech): Factors affecting clinical pregnancy loss following euploid embryo transfer in PGT-A cycles: a machine learning approach.

This research reflects Instituto Bernabeu’s commitment to addressing, on the basis of scientific evidence, some of the most pressing questions in modern reproductive medicine, with the aim of translating laboratory advances into clinical practice and improving patients’ chances of success.

Participation in ESHRE 2026 reaffirms Instituto Bernabeu’s commitment to biomedical research and to generating knowledge that will enable it to continue offering innovative, safe and increasingly personalised treatments.
