UCLA Engineers Shed New Light on 3-D Motion of Human Sperm Cells

Using new lensless imaging platform, team observes rare helical movements

A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has, for the first time, directly recorded the three-dimensional helical swimming patterns of human sperm cells.

The team, led by Aydogan Ozcan, associate professor of electrical engineering and bioengineering, developed a novel lensless computational imaging platform that accurately tracked more than 24,000 individual sperm cells in a large volume. This involved observing the individual rotations of each sperm cell, including helical movement patterns, rotation speed, and linear and curved distances traveled. (more…)
