Freezing is now an essential part of every clinic's IVF programme. In fact, studies have proven that results are better when embryos are transferred in later non-stimulated cycles rather than directly following egg collection. Thanks to improved freezing techniques, clinics across the UK – and across the world - are moving towards freezing all embryos and transferring them at a later date once the female partner’s body has returned to normal following stimulation.
One by One IVF
This approach is at the heart of the London Women’s Clinic pioneering One by One IVF programme that is only available at a handful of top clinics world-wide so far. One by One IVF is an innovative, new programme which involves freezing all embryos in an IVF cycle and transferring after thawing ‘one-by-one’ in later non-stimulated cycles. This maximises cumulative live birth rates per IVF attempt while minimising multiple pregnancies, which increases the health risks for both mother and baby.
Spare embryos from your IVF treatment can be frozen for future use, depending on their quality. Embryos can be stored for up to ten years for future treatment if your first cycle was unsuccessful or for siblings.
