IVF Select is an innovative, approach to assisted reproduction that involves
- Freezing all embryos in an IVF cycle,
- Testing of embryos for unbalanced chromosomes
- Transferring after thawing one at a time in later non-stimulated cycles.
Embryos with abnormal numbers of chromosomes or parts of chromosomes rarely develop into a pregnancy and healthy baby. These are the most frequent causes of IVF failure and miscarriage, especially in older patients. This technique maximises cumulative live birth rates per IVF attempt and minimises multiple pregnancies, which increases the health risks for both mother and baby.
The London Women's Clinic team at London Bridge is one of only a handful of clinics around the world who have pioneered this treatment. The resulting outstanding pregnancy rates, across a wide range of maternal ages, mean you can maximise your chance of a healthy baby.
Key points about IVF Select
- Selection of embryos based on genetic as well as morphological quality.
- Higher pregnancy rates per embryo transferred.
- Lower chance of miscarriage.
- Fewer embryo transfers needed to achieve pregnancy
- There may be fewer embryos available for transfer.
- Does not remove the need for prenatal chromosomal screening.

How does IVF Select work?
IVF Select incorporates many of the latest innovations in IVF to maximise the chances of a successful and safe single pregnancy:
- Ovarian stimulation individually tailored to optimise the number of mature eggs collected in a single IVF treatment cycle
- Embryos are cultured to the blastocyst stage and monitored by time-lapse imaging
- Unlimited embryo testing for genetic imbalances (aneuploidy and structural abnormalities) by 'Next Generation Sequencing' (NGS) chromosome copy number analysis
- No embryo transfer in the fresh cycle to avoid ovarian hyperstimulation syndrome (OHSS) and improve the chance of pregnancy
- All blastocysts are vitrified (frozen) with a series of transfers of single genetically balanced blastocysts
