Selecting normal embryos can increase the pregnancy chances after transfer.
In the general population, 25% of all clinical pregnancies
end in miscarriage.
Some pregnancies with chromosomal anomalies can give rise to the birth of baby with a serious illness.
According to internal data and several independent clinical studies, selecting normal embryos might increase the pregnancy possibilities after transfer.
In the general population, 25% of all clinical pregnancies end in miscarriage and almost half are chromosomally abnormal.
Therefore, especially in high-risk groups, the PGS reduces the risk of misscarriage.
The PGS increases the possibility of having a healthy baby, as it allows chromosomally normal embryos to be identified.
The mean theoretical time to achieve a LB (weeks) decreases from 14.9 to 7.7 weeks with PGS (1)
PGS helps to avoid repeating cycles of assisted reproduction and can help to reduce the number of multiple pregnancies performing by supporting single embryo transfer
We use the most advanced technology, NGS (Next-Generation Sequencing) to perform the PGS test:
Our technology and experience allows to analyse 24 chromosomes with an accuracy of 99% among all cases.
Turn Around Time after receiving the samples in our laboratory: FRESH CASES: 24 - 48 HOURS | FROZEN CASES: 10 WORKING DAYS
Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy.
