The product · EVA

Selection, by
behaviour — not force.

EVA is a biomimetic microphysiological system that turns sperm preparation from a blunt mechanical step into a faithful copy of biology. Inside, the most capable cells reveal themselves the same way they would on the path to the egg.

How EVA works

Four steps that copy a journey millions of years old.

STEP 01

Recreate the tract

Turn on the thermotaxis puck and plug in the disposable chip. The coupling of puck and disposable reproduces the temperature gradient, geometry, and flow conditions of the female reproductive tract — the environment sperm evolved to read.

STEP 02

Load the sample

A raw semen sample enters the disposable's intake via pipette. No spinning, no harsh chemistry — the cells stay in the condition you collected them.

STEP 03

Let thermotaxis decide

Only cells with the physiological fitness and sensing capability to follow the cue swim toward the collection point. Selection happens by capability, the way nature intended.

STEP 04

Collect the best

The selected fraction is recovered by pipette, ready for IVF, or ICSI — higher motility, better DNA integrity, and no mechanical damage.

Typical processing time from loaded sample to selected fraction: 20–30 minutes, spanning the tract-recreation and thermotaxis-selection steps.

Why it matters

Better in, better out.

The single cell chosen for fertilisation shapes everything that follows. Standard centrifugation selects on density and survives the spin — not on the qualities that actually predict a healthy embryo. EVA changes the input, so clinicians start every cycle from a stronger position.

  • Gentler on the sample, kinder on the patient
  • Fits existing embryology workflows and benches
  • Low energy, low footprint, fully reproducible
