Abstract :The irruption of new technologies based on nanotechnology and new knowledge about the behavior
of spermatozoa deriving from fluid mechanics are opening new pathways enabling specific cells or
populations to be selected and subsequently monitored and led through a variety of systems. In the
near future, spermatozoa will be "tamed" and used not only for reproductive purposes but also forth
erapeutic ends. These advances will promote and improve the development of assisted reproductive
technologies, enabling more successful results to be obtained. What follows is a review of the more
interesting advances related to sperm monitoring, selection and utilities, in the form of a global
overview of the potential future innovations in this field.
