New chip could pick healthier sperm for IVF
NCT ID NCT03085433
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a microfluidic chip that gently separates healthy, motile sperm from semen without harsh chemicals. Researchers compared it to the standard spinning method in 393 couples undergoing IVF for unexplained infertility. The goal was to see if the chip leads to higher-quality embryos on day 3 of development.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Microfluidic sperm sorting device
What this could lead to
If successful, this device could become a standard, gentler way to select sperm for IVF, potentially improving embryo quality and pregnancy chances.
What could go wrong
This is a completed trial, but the improvement in embryo quality may not translate into higher live birth rates. The device may not work for all types of male infertility.
