What this research studies

As more women choose to freeze their eggs, we know that frozen eggs can sometimes lead to lower live birth rates compared to fresh eggs. This project looks at tiny packages called extracellular vesicles (EVs) that cells naturally release, which contain important regulatory molecules. We believe these EVs, particularly those from the fluid around the egg, could help damaged eggs recover after freezing. Using a domestic cat as a model, we aim to understand how these EVs work and if adding them can improve the quality and function of frozen eggs, ultimately leading to better outcomes for patients.

Who could benefit from this research

Good fit: This foundational research is for women who are considering or undergoing egg freezing and other assisted reproductive technologies.

Not a fit: Patients not undergoing fertility treatments or egg freezing would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new ways to improve the quality of frozen eggs, potentially increasing live birth rates for women using assisted reproductive technologies.

How similar studies have performed: Other studies have shown that adding extracellular vesicles can improve early embryo development and egg quality in laboratory settings.
