Eugin promotes a pioneering study to understand the molecular changes in eggs produced by the passage of time

The final results will show the epigenetic profile of the eggs and will help us have a better understanding of their relationship with women’s fertility

To know the molecular composition of the egg in order to enhance our knowledge of female fertility is the aim of the study promoted by Eugin Clinic and presented at the annual meeting of the European Society of Assisted Reproduction and Embryology (ESHRE, its acronym in English), held in Lisbon from 14 to 17 June. For the first time ever, as many as 500,000 genes in a woman’s oocytes have been studied.

“This is a really cutting-edge study from a research point of view,” explains Dr. Rita Vassena, Eugin’s scientific director and author of the paper, entitled “Age and Ovarian Reserve Affect The Non-Coding Transcriptome Of Human Oocytes” . “Never before had these types of molecules been observed in a woman’s oocytes,” she adds.

“We are observing the changes undergone by the molecular composition of the eggs over the years. All this will enable us in the future to predict what the state of health of a woman’s ovaries is, and therefore better understand her fertility”, claims Dr. Vassena.

Collaboration with the Barcelona Science Park

The study was conducted in the basic research laboratory that Eugin has in the prestigious Barcelona Science Park, where the assisted reproduction centre works to deepen its knowledge of fertility.

The clinic also collaborates in different scientific projects with working groups from well-known universities such as the University of Milan, Leeds University, Cardiff University, Ghent University and the University of Barcelona, which gives their research a high degree of diversity, richness and internationality.

Benchmark event

Lisbon hosts this week’s annual meeting of ESHRE, where thousands of professionals present the most outstanding developments from the embryology and assisted reproduction sectors. This year, Eugin has played a very prominent role, since it will present up to eight studies of its own during the course of the event.
