About Egg Freezing

Egg freezing – oocyte cryopreservation - is a medical procedure where a number of your eggs are extracted from your ovaries and frozen for use in the future. Freezing stops your eggs from ageing, meaning that you could still have the option of genetic motherhood when you are older.

Whilst egg freezing has been offered to women facing fertility-threatening medical treatments such as chemotherapy for some years, freezing for elective reasons has only been offered in clinics in the past few years - since the American Society of Reproductive Medicine (ASRM) announced in January 2013 that the practice was no longer “experimental”. Despite the ASRM also warning against using egg freezing “for the sole purpose of circumnavigating reproductive ageing in healthy women” due to a lack of sufficient data, the procedure has been gaining popularity among women wanting to preserve their fertility. This is commonly referred to as 'social egg freezing'.

The products in the Timeless range give further information on the process of egg freezing, the current success rates, and age-related fertility decline.
