FERTILITY PRESERVATION

Egg Freezing

Egg freezing, also known as oocyte cryopreservation, is an assisted reproduction technology (ART) technique that freezes and stores a woman’s unfertilised eggs for conception at a later stage of her life.

Owing to various reasons and personal pursuits, more and more people are delaying child-bearing. Egg freezing offers hope of still having healthy eggs for reproduction by the time they are ready. 

Starting from 1 July 2023, women aged between 21 and 37 will be legally permitted to freeze their eggs for non-medical reasons in Singapore through Elective Egg Freezing, which will be available at Thomson Fertility Centre. The age limit for women to freeze their eggs in order to preserve their fertility will be raised from 35 to 37, based on findings that demonstrate that the success rates of egg freezing and use of frozen eggs remain steady for women up to 37 years of age.

However, only legally married couples can use their frozen eggs to try for a baby through in-vitro fertilisation (IVF). 

Currently, women can freeze their eggs in Singapore for future use if there is a medical reason involving a permanent impact on their fertility, such as having to undergo:

• Gynaecological surgery to remove tumours, affecting the ovaries, uterus and/or fallopian tubes
• Chemotherapy, which can damage a woman’s eggs
• Radiotherapy in the pelvic region that may induce premature menopause

Egg-freezing provides them option to preserve their eggs before they are damaged or depleted, allowing them the chance to still have babies post-recovery.

How is egg freezing conducted?

Similar to the initial stages of an IVF cycle, a woman has to undergo daily injections of hormones to stimulate the growth of eggs until they reach a mature stage for retrieval.

The retrieved eggs are then frozen and stored. They can be thawed when the woman is ready to try for a baby.

Sperm Freezing

Like egg freezing for women, sperm freezing is an option for men who needs to preserve their fertility due to medical reasons. Semen containing sperm will be collected and frozen before they start on their chemotherapy, radiotherapy or surgical treatment.
