Dr Razina Patel walks through elective (social) egg freezing step by step, from ovarian stimulation and monitoring to egg collection, vitrification and storage.

Egg freezing means going through the first half of an IVF cycle — daily injections to stimulate the ovaries, scans and blood tests to monitor the response, and a short procedure under sedation to collect the eggs — and then freezing the mature eggs by vitrification rather than fertilising them. When you want to use them, the eggs are thawed, fertilised with sperm (usually by ICSI), grown in the laboratory and transferred as an embryo. Freezing eggs does not guarantee a baby later. How likely a stored batch is to lead to a birth depends on your age when the eggs were frozen, how many mature eggs were collected, how many survive thawing, how many fertilise, how the embryos develop and what happens at transfer. Younger age at freezing and a larger number of mature eggs both improve the odds, but no number of eggs makes it certain. Ask your clinic for their own thaw and live-birth figures, and for their storage costs and consent terms before you start.

Recorded in 2022. The stages of treatment described are unchanged, but storage fees, consent paperwork and any clinic-quoted success figures should be confirmed with your own South African clinic.

Key takeaways

  • Egg freezing uses the same stimulation, monitoring and egg collection steps as the first half of IVF.
  • Mature eggs are frozen by vitrification and stored; they are thawed, fertilised and grown into embryos when you want to use them.
  • Freezing eggs does not guarantee a future baby — outcomes depend on age at freezing, number of mature eggs, survival, fertilisation, embryo development and transfer.
  • Ask your clinic about storage fees, consent terms and their own thaw and live-birth figures.
