Selecting sperm using microfluidics for ICSI
Clinical Outcomes Following the Sperm Selection by Rheotaxis and Thermotaxis in In-Situ Hand-made Microfluidics of Fluidic Walls in the Same ICSI Plate: a Randomized Controlled Trial
This study is testing a new way to pick the best sperm for ICSI using a special technique that could make the process easier and more effective for couples trying to conceive.

What this trial studies
This study evaluates a novel microfluidics approach for selecting sperm for intracytoplasmic sperm injection (ICSI) by utilizing rheotaxis and thermotaxis. Unlike traditional methods that involve washing and centrifugation, this technique allows for sperm selection directly within the ICSI dish, streamlining the process and reducing potential handling errors. The study aims to compare the effectiveness of this new method against conventional density gradient centrifugation in selecting motile sperm from raw semen samples. The goal is to improve the efficiency and outcomes of assisted reproductive techniques.
Who should consider this trial
Good fit: Ideal candidates for this study are women under 40 years old undergoing ICSI with at least 6 mature oocytes and men under 50 with a minimum of 1 million progressive sperm.
Not a fit: Patients using surgically retrieved sperm or cryopreserved gametes will not benefit from this study.
Why it matters
Potential benefit: If successful, this method could enhance sperm selection efficiency, leading to improved fertilization rates in ICSI procedures.
How similar studies have performed: Previous studies have shown promising results with microfluidics in sperm selection, indicating potential for success with this novel approach.
