Egg Freezing (Oocyte Cryopreservation)

Freezing unfertilized eggs to preserve fertility potential.

Overview

Egg freezing involves ovarian stimulation and retrieval followed by vitrification of unfertilized mature oocytes for future use.

Common Indications

  • Elective fertility preservation
  • Before medical treatment that may affect fertility
  • Personal or professional timing considerations

How It Works

  1. Ovarian stimulation and monitoring.
  2. Egg retrieval under sedation.
  3. Vitrification of mature eggs.
  4. Storage until intended use.

Considerations

  • Success in later use depends on the number and quality of eggs frozen, which is strongly age-related.
  • Freezing does not guarantee a future live birth.
