Are Sperm a Living Creature?

[Sid Lipkin]

Always wondered this...Is human sperm classed as a living creature?
  Is there a genus of animals that it belongs to?  Can sperm survive
  outside the human body(in a lab setting)?

   What about anti-bodies?  are they Alive in the sense that we define life?
     They have a purpose and act according to certain criteria?  is this life?

  Sorry if this is uneducated...just curious
