Sperm Dynamics in Tubular Confinement

An on-chip system that mimics tubular microenvironments is presented for the study of spermatozoa motion in confinement. Using rolled up transparent silicon oxide/dioxide microtubes, the influence of tube diameter on the velocity, directionality, and linearity of spermatozoa is investigated. Tubular microenvironments of diameters 20–45 μm facilitate sperm migration through channels.
