What this trial studies

This study evaluates the impact of hyaluronan-enriched transfer medium on the cumulative ongoing pregnancy rate in patients undergoing oocyte retrieval. It involves a randomized controlled approach where patients with their own oocytes or embryos and specific eligibility criteria will be treated with this enriched medium. The goal is to determine if this intervention can enhance pregnancy outcomes compared to standard practices.

Who should consider this trial

Good fit: Ideal candidates are women under 40 years old who are undergoing a second or third oocyte retrieval without a clinical ongoing pregnancy from previous attempts.

Not a fit: Patients who are older than 40 years or have a BMI over 32 may not benefit from this study.

Why it matters

Potential benefit: If successful, this could lead to higher pregnancy rates for patients undergoing fertility treatments.

How similar studies have performed: Other studies have shown promising results with similar approaches using enriched media in fertility treatments.
