A group of Canadian scientists are perfecting a microscopic ‘sperm obstacle course’ to help doctors select the finest specimen for in-vitro fertilization.
The team developed the device that hosts a microscopic competition between 100,000,000 sperm. When inserted into the microchip device, the swimmers go through a kind of “regional qualifiers” obstacle course to narrow the field down to 1,000. Instead of allowing the sperm to swim freely in a “corkscrew” motion without boundaries, the device requires the sperm to navigate a two-dimensional plane.
Sperm are particularly adept at slithering when they want to power through confinement or an area of thick fluid, much as they do through fallopian tube, he said. The new technology is a solution that mimics nature more closely.
