Fertile Chip is a device that allows the selection of the most mobile spermatozoa. It is a support with two chambers connected by a channel. The semen is deposited in the entry chamber and, half an hour later, the spermatozoa that have managed to reach the collection chamber are selected.

The use of this technique is indicated for low quality semen samples with high DNA fragmentation.

Fertile Chip is a simple and quick procedure that also avoids the centrifugation of the semen. The spermatozoa obtained have, among other characteristics, better motility, morphology, fewer reactive oxygen species and less fragmentation.
