Sperm Tail-Tracking Technique Could Improve Male Fertility Testing

Sperm tail-tracking technique analyses how sperm tails move and consume energy.

Tracking the movement of a sperm’s tail, or sperm tail-tracking, could improve male fertility testing and lead to more effective treatments, according to a new study. sperm tail tracking

The technique developed by researchers at the University of Birmingham, works by measuring the speed and action of the sperm flagellum, or tail.

By analysing the tail, it is possible to decipher whether the sperm in an ejaculate have the potential to reach and fertilise the egg, they said as they published their findings in the journal Human Reproduction.

Currently, analysing sperm is either done by counting the number of sperm produced or by tracking the head of the cell.

However, “diagnostic methods are crude and there are still no drugs available for treating male infertility,” said researcher Jackson Kirkman Brown MBE.

The new sperm tail-tracking technique uses a combination of rapid, high-throughput digital imaging, mathematics and fluid dynamics to detect and track sperm in samples.

To ensure the method is accessible to other researchers and clinicians, the team have developed a free-to-use software called FAST (flagellar capture and sperm tracking).

This will lead to an improved understanding of male fertility problems, and how to treat them, the researchers said. 

“We have all heard of ‘sperm count’, and indeed the tools available to understand sperm – manual counting with a microscope – have not changed much since the 1950s,” said lead researcher Professor Dave Smith.
