Comparing sperm selection methods for intrauterine insemination

Evaluation of Live Birth Rate After Sperm Selection Using Microfluidic Technology (ZyMōt Multi (850µL) Sperm Separation Device) for Intra Uterine Insemination.

Not applicable Interventional Universitair Ziekenhuis Brussel · NCT06144268

This study is testing two different ways to prepare sperm for couples trying to get pregnant through intrauterine insemination to see which method leads to more successful pregnancies.

What this trial studies

This pilot randomized control study aims to evaluate the effectiveness of two sperm preparation methods for couples undergoing intrauterine insemination (IUI). Participants will be randomly assigned to either the standard Density Gradient Centrifugation (DGC) method or the ZyMōt Multi (850µL) device. The primary outcome will be the live birth rate following the IUI procedures, assessing which method yields better results in terms of successful pregnancies. The study focuses on couples facing various infertility issues, including mild male factor infertility and unexplained infertility.

Who should consider this trial

Good fit: Ideal candidates include women under 37 years old with mild infertility issues and a sufficient sperm count for IUI.

Not a fit: Patients with advanced endometriosis or significant intracavitary pathology may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve live birth rates for couples undergoing IUI by identifying a more effective sperm selection method.

How similar studies have performed: Previous studies have shown varying success with different sperm selection techniques, but this specific comparison is relatively novel.
