IVF Statistics
*The following stats were from 2016 – 2019. For the latest IVF Statistics please refer to this page.
We have been very active in embryo biopsy technology in IVF since 1999. Our first pregnancy for pre-implantation genetic diagnosis for prevention of a genetic disease was achieved in late 1999 with a live birth in 2000. In 2012, our IVF program shifted to blastocyst laser assisted trophectoderm biopsies and almost exclusively Single thawed euploid (23 chromosomes) embryo transfers. Since then, almost all our IVF treatments include genetic testing of embryos in order to try to implant single embryos to prevent all the very serious complications that can occur with twin and higher order pregnancies. Our results herein are intermittently audited by an independent auditor from American Accounting of Sarasota, Florida. They review the charts and verify that there are no errors in our reporting or in the calculations.
All ages of patients treated are combined.
2019: All PGS or PGTa thawed embryo transfers (includes 3 cases with w 2 embryos transferred) Pregnancy rate = 81%, 64% ongoing pregnancies
2019: Single thawed (single embryo transferred) PGS or PGTa embryo transfers, Pregnancy rate = 82%, 64% ongoing pregnancies.
2018: All PGS or PGTa thawed embryo transfers, pregnancy rates = 70%, Live births/ongoing pregs. = 57%
2018: Single PGS or PGTa thawed embryo transfers, pregnancy rates = 68%, Live births/ongoing preg.=55%
In 2018, there were 7 thawed PGS embryo transfers when 2 embryos were transferred. Six resulted in pregnancies, two of them being twin pregnancies.
2017: All Pre-implantation Genetic Screening thawed embryo transfers Pregnancy rate = 77%, Live births = 52%*
2017: Single PGS Thawed embryo transfers (single embryo transferred): Pregnancy rate = 78%, Live births = 53%*
In 2017, there was 1 treatment when 2 thawed embryos were transferred after PGS and that resulted in our only twin pregnancy for 2017.
*In 2017 there was one unknown result for live birth. There was also 1 single embryo transfer (only one embryo implanted) that resulted in a twin pregnancy with live birth of twins. Also, in 2017 there were 3 thawed PGS embryo transfers when 2 embryos were transferred. Two resulted in pregnancies (one twin live birth and one singleton live birth).
2016: All PGS or PGTa Frozen/thawed embryo transfers, Pregnancy rate = 81%, Live births= 62%
2016: Single PGS or PGTa thawed embryo transfers (only 1 embryo implanted): Pregnancy rate = 80%, Live Birth = 59%
In 2016, There were 4 thawed PGS embryo transfers when 2 embryos were transferred. All resulted in pregnancies. Three were singleton births and one a twin birth.
Explanation:
The word “Euploid” is a genetic term that describes the presence of a normal number (23 pairs) of chromosomes. Single Euploid Embryo Transfer IVF Statistics are what really matter. IVF treatments are changing, as are IVF statistics. We are among the most progressive IVF clinics around the world that have embraced new technologies that have improved embryo selection processes.
It is well known that the most common complication of Assisted reproductive techniques are the complicated multiple pregnancies (twins, triplet, and higher number pregnancies) that result when more than one embryo is implanted (or transferred). For example, twin pregnancies have as much as a 4-6 times higher risk of congenital anomalies, 4-6 times higher risk of cerebral palsy, as well as many other pregnancy complications including a 4 times higher risk of fetal death and need for a cesarean section. With that in mind, top doctors and scientists have tried to develop new IVF technology for selecting single embryos for transfer for all patients regardless of the mother’s age.
Past protocols were simply based on the appearance of the embryos. It had been standard practice to implant or transfer 1 or 2 embryos if the patient’s age was less than 32, 2 embryos if the egg age was 32-36, 2-3 embryos would be implanted if the patient was 36-39 years old and so on. Patients in their 40’s would routinely receive 4-5 embryos. This was the case because the older the egg, the higher the chance of a genetic abnormality that would prevent development past the earliest stages. For the past 20 years, the average IVF Statistics for twin pregnancy rate per IVF in the younger patients was 25-30%. That was such a large number that if one saw a twin pregnancy or twins, there was 65% chance that the pregnancy was the result of some type of Assisted reproductive technique.
Our goal has been to apply technologies that would give us so much information about the embryo that we could shift our IVF program to a single embryo transfer program regardless of the maternal age. That is, for example, a 23 year old, a 35 year old, a 43 year old would all have the same plan for a single embryo transfer and therefore avoid the risks associated with a multiple pregnancy.
We have been leaders in Florida in the application of pre-implantation genetic screening (PGS) and pre-implantation genetic diagnosis (PGD) as evidenced by our first pregnancy in 1999 and the subsequent delivery of that healthy baby girl in 2000. From 1999 until the present, the instruments, techniques, and processing of the cells from the embryos have evolved so that we gather more information and have much more reliable results. From 1999 until the end of 2012, we based our decisions on one or two cells taken from a 3 day old embryo. Since 2013, we have shifted to testing the 5 or 6 day old embryo. This allows us to test a smaller portion of the embryo and at the same time test a larger number of cells (8-10) that are more advanced. These cells are from the trophectoderm or future placenta.
In 2017, we instituted audits of our results by and independent accounting firm. American Accounting of Sarasota has audited our Pre-implantation Genetic Screening program for 2016 and the first half of 2017. We chose to do this because we are ahead of the trend in reporting what really matters: cumulative age IVF Statistics per single euploid (23 pairs of chromosomes detected) embryo transfers.
