text: Vitrification, "Open" devices, they be so fly,
  Cryoloop, cryotop, cryoleaf, Vitriplug, oh my!
  Cooling rate be 20,000 °C/min, that's the aim,
  Liquid nitrogen contact, we in the game.
  
  Debate on contamination, it's up in the air,
  But we gotta revise, show we care.
  EU directive got advice to share,
  Separate the embryos, handle with care.
  
  Cooling and storage, embryo carriers gotta be tight,
  Keep 'em safe from liquid nitrogen, day and night.
  Minimize the risk, that's the goal,
  Contamination's something we gotta control.
  
  Heat-insulating barriers slow down the freeze,
  But we got a trick up our sleeves.
  Increase cryoprotectant, let it rise,
  Toxic effects, we gonna minimize.
  
  Aseptic vitrification, our method's so clean,
  MII oocytes and embryos, they be pristine.
  Using "VitriSafe," a "closed" carrier device,
  We on the cutting edge, ain't no need to think twice.
