Sperm Selection by Microfluidic Separation Improves Embryo Quality

University of California, San Francisco·interventional·Posted Mar 21, 2017·Updated Dec 31, 2025

In Brief

A clinical study evaluating Microfluidic Sperm Sorting and in vitro fertilization for Sperm DNA Fragmentation and 5 related conditions. Completed, enrolled 393 participants across 1 site.

Detailed Summary

This is a randomized controlled trial of couples with a history of poor embryo quality undergoing a repeat in vitro fertilization (IVF) cycle for unexplained infertility. Couples will be randomized to sperm selection by the clinical standard of centrifugation and density-gradient processing compared to the microfluidic sperm sorting chip.

Interventions

Microfluidic Sperm Sortingdevice

Microfluidic technology isolates healthy sperm by laminar flow, creating gradients through channels. The microfluidic chip we plan to study in our randomized clinical trial utilizes space-constrained microfluidic sorting to select highly motile and morphologically normal sperm in a flow and chemical-free design. Unlike the standard of density gradient centrifugation, no manipulation of sperm is required in this process. Raw semen is introduced into the inflow and only motile and morphologically normal sperm are able to swim through the chip to the outflow where it is collected for use.
