Don't spend countless hours accurately modeling and rigging a sperm, I've done it for you!
This sperm is perfect for medical visualizations. The sperm swims in a scientifically accurate helix pattern, automatically when moved along the Z-Axis. The swim can be adjusted through a series of parameters such as "Swim Amplitutde" and "Swim Speed". A dynamics toggle can add a little more realism to your wriggle. Materials are created to function well in Viewport 2.0. The materials are all default Maya materials and will render as expected.
