Dynescan Semen Quality Analyser

The Dynescan semen analyser, is the first technology to measure the semen lifetime (% progressive motility and swimming speed over time), providing new insights into whether semen motility is likely to be sustained within the cow.

Dynescan Semen Analyser

New insights,
over time...

Access to Sustain Motility Lifetime data to provide quality assurance on fresh semen or straws on-farm where it matters.

% Prog. Motility

Progressive motion is defined as that when cells are moving in a fairly straight line so that they progress across the sample.

Swimming Speed

Mean swimming speed is defined as the average (mean) swimming speed measured for all cells that are considered progressively motile.

Semen QC, where it matters

Semen quality is highly variable and can deteriorate over time causing undesired results. With a Dynescan you take control of the semen quality to inform precisely the AI protocol selection.

Easy to use & Automated

Dynescan has been designed to protect semen samples from the wind and cold to provide reliable measurements at 37.5 degrees Centigrade.


In visual mode, you are able to see spermatozoa moving, as you would down an ordinary microscope.

Measurements with the Dyneval mode are completely automated for easy of use.  This means that:

  • no prior training is required
  • every user will obtain very similar results for a given sample
  • data is stored securely on the cloud


Dynescan offers the highest precision for semen motility assessment.

The standard deviation error is <3% for measurements on aliquots taken from the same batch of semen. Published work using computer aided semen analysis (CASA) reports a standard deviation of 10% or more.

In single measurement mode obtain a one-off reading of the percentage of progressively motile spermatozoa (% motility) and the mean speed.

In continuous measurement mode, leave the instrument to collect data at regular intervals and collect valuable datasets to strengthen your understanding of long-term motility (typical result shown in figure).


Dynescan can be used anywhere that mains power is available, on farm, in the clinic or at the laboratory. Dynescan comes in a robust, water-resistant case which will withstand everyday knocks and bumps.  

Dynescan measures just 25.4cm x 13cm x 30cm with a total weight less than 5kg.
