What is egg freezing?
Egg freezing (oocyte cryopreservation) collects a woman's eggs and freezes them for potential use later. It can be done for medical reasons (for example before treatment that may affect fertility) or electively, to keep future options open. Frozen eggs can later be thawed, fertilised and transferred as part of IVF.
Who considers it
- Women who wish to preserve fertility for the future
- Those facing medical treatment that may affect fertility
- People who want flexibility around the timing of family planning
The process
Similar to the first half of an IVF cycle: ovarian stimulation with medication, monitoring, and egg retrieval under sedation. The collected eggs are then frozen. The number of eggs retrieved and their future potential depend strongly on age at the time of freezing.
Important considerations
Egg freezing does not guarantee a future pregnancy, and success when eggs are later used depends on age at freezing and other factors. In Singapore, eligibility, age limits and the conditions for later use are regulated, so it is important to understand the rules and have realistic expectations. A fertility specialist can explain these in detail.
When to see a specialist
If you are considering preserving your fertility, an early conversation with a specialist helps — because outcomes are generally better when eggs are frozen at a younger age.
