Comparing two methods for processing semen quality in infertility treatment

Effect of Sperm Preparation by a Microfluidic Chip Method Versus a Density Gradient Centrifugation Method on Semen Parameters

Not applicable Interventional The University of Hong Kong · NCT05978947

This study is testing a new way to process semen to see if it can better preserve sperm quality for men undergoing infertility treatment compared to the traditional method.

What this trial studies

This study evaluates the effectiveness of a new microfluidic chip technology against the traditional density gradient centrifugation method for processing semen in men attending a fertility clinic. The research aims to determine which method better preserves sperm quality, specifically focusing on DNA fragmentation, sperm count, and motility. Participants will have their semen samples randomly assigned to one of the two processing methods, and various tests will be conducted to assess the outcomes. The goal is to improve IVF success rates by enhancing the quality of sperm used in fertilization.

Who should consider this trial

Good fit: Ideal candidates for this study are men with a sperm concentration of at least 5 million motile sperm per ml and a total semen volume of not less than 1.5 ml.

Not a fit: Patients with a sperm concentration of less than 5 million motile sperm per ml or those unable to provide an ejaculated semen sample may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved sperm quality and higher IVF success rates for couples facing infertility.

How similar studies have performed: While the use of microfluidic technology in semen processing is a relatively novel approach, similar studies have shown promising results in improving sperm quality.
