A short companion to the orientation video, focused on what happens to eggs in the laboratory.

This explains laboratory technique rather than your own treatment plan. Numbers of eggs collected and later outcomes vary considerably between individuals.

Key takeaways

  • Vitrification is rapid freezing that limits ice-crystal formation.
  • Frozen eggs are warmed and fertilised when you decide to use them.
  • Egg numbers and later outcomes differ from person to person.
