Improving egg freezing techniques for fertility treatments
Validation of Semi-automatic Oocyte Vitrification by the GAVI® Machine in Medically Assisted Reproduction With Oocyte Donation
This study is testing a new way to freeze donor eggs to see if it helps them survive better and leads to more successful pregnancies when used in fertility treatments.

What this trial studies
This study evaluates the effectiveness of a semi-automated vitrification method for freezing donor oocytes compared to traditional manual techniques. The research aims to assess the survival rates of oocytes after warming and their subsequent fertilization success using intracytoplasmic sperm injection (ICSI). By utilizing closed devices for storage, the study seeks to minimize variability and improve the consistency of oocyte preservation. The outcomes will include the quality of embryos developed from vitrified oocytes and their potential for successful pregnancies in assisted reproductive technology.
Who should consider this trial
Good fit: Ideal candidates for this study are women who are egg donors with a good quality ovarian reserve and meet specific health criteria.
Not a fit: Patients who are pregnant, lactating, or unable to provide informed consent will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the success rates of fertility treatments by improving the preservation of donor oocytes.
How similar studies have performed: Previous studies have shown promising results with automated vitrification techniques, indicating potential for success in this approach.
