At the Zita West Clinic we pride ourselves on using evidence-based science and technology to improve IVF success rates. Here are just a few of the technologies we can use to help you have a baby.
Endometrial Receptivity Analysis
Endometrial receptivity analysis (ERA) is a way of finding out when the lining of the womb is most receptive, meaning we can then decide a time for embryo transfer that’s most likely to result in success. While there can be many reasons that an embryo won’t implant, sometimes there may be a problem with the endometrium which can then cause failed cycles.
What is the ERA procedure?
ERA testing can be doing either during a natural cycle or a conventional IVF cycle, with a test similar to a smear where tissue it taken from the womb lining. This is then analysed to see when the endometrium would be most effective to help decide the timing of implantation.
Time lapse technology
Time lapse embryo imaging is an additional procedure available to all our patients to help make embryo selection even more effective.
Once the eggs have been fertilised, photographs are taken of the embryos, without disturbing them, every few minutes. Calculations about what the embryo should be doing at specific points in time are then used to analyse the health of the embryo to see their chances of success.
As we know, one set of chromosomes from the sperm and one set of the egg form the first cell of an embryo, but if the cell doesn’t have the right amount of chromosomes (known as aneuploidy), this can lead to implantation failure, miscarriage or a baby born with a serious condition.
At the Zita West Clinic, we can carry out a genetic screening test called Pre-implantation Genetic Testing for aneuploidy (PGT-A) on embryos produced during an IVF treatment cycle. PGT-A helps us select the best embryo for transfer and may improve your chance of achieving a successful pregnancy.
There are many benefits to this technology, from potentially reducing the number of IVF cycles needed, to giving more confidence in transferring a single embryo.
You can find out more key information about PGT-A genetic testing, including its potential risks and evidence of success, on our Genetic Testing page.
Who should consider PGT-A?
For those who have experienced miscarriages or failed treatments then we may suggest this for you. There has also been research to suggest that over half of human eggs have chromosomal issues which increases with age, so many women who are over 35 may also choose PGT-A.
The PGT-A process
When embryos reach the Blastocyst stage after 5-6 days, they contain around 100 to 200 cells arranged into an inner cell mass and an outer ring of cells. The inner cell mass is made up of stem cells that will go on to form the foetus, while the outer ring (the trophectoderm) will become the placenta. A few of these trophectoderm cells are carefully removed by our embryologists for assessment before freezing the embryos.
