Damn lazy sperm needs a microbot to help it

".., a helix of magnetic material spins around its axis under a rotating magnetic field. These devices are easier to control: changing the field's orientation and frequency alters the direction and speed of the motor. Such 'magnetic swimmers' mimic flagella, the tails that propel some microorganisms4. Ultrasound, too, can be used for propulsion and guidance"
