How we measure our IVF success rates
Our Las Vegas IVF doctors are proud to report some of the highest IVF success rates in the United States, year after year.
The law requires all certified IVF laboratories, including ours, to submit data about their IVF success rates each year to the Centers for Disease Control and Prevention (CDC). The CDC then publishes these rates for each clinic that is a member of the Society for Assisted Reproductive Technology (SART).
SART and the CDC track data for several different types of IVF, as outcomes vary depending on the protocols and processes used.
- IVF success rates
- FET success rates
- Donor egg success rates
While SART and the CDC are both excellent resources for choosing a fertility center, there are important considerations to keep in mind when evaluating and comparing IVF success rates.
Understanding IVF success rates
Our Las Vegas IVF doctors measure our IVF success rates based on two main criteria.
- Live birth rate per embryo transfer
- Live birth rate per cycle start
To compare the success rates of different fertility centers, it’s important to understand the difference, as well as the impact of maternal age on IVF outcomes.
The live birth rate per embryo transfer is the percentage of couples who both have viable embryos to transfer and have a child after an embryo transfer. This number stays about the same for all age groups of women and men.
However, the ability to produce viable embryos declines as women age, so some women will not have viable embryos to transfer – especially women who are older than 38 and are undergoing IVF using their own eggs. This is where the live birth rate per cycle comes into play. These IVF success rates decline dramatically for women in their late 30s and beyond because many do not have enough viable eggs to produce embryos for transfer.
Another key measure to look for is the average number of embryos transferred. Our Las Vegas fertility centers have high confidence in our laboratory and clinical practice, enabling us to achieve excellent outcomes when transferring just one embryo. Single embryo transfer reduces the odds of a high-risk multiple pregnancy, improving safety for both the mother and her baby.
Fertility centers with inferior laboratories and lower implantation rates may try to artificially inflate their live birth rate per transfer by transferring more than one embryo. While this may achieve pregnancy and compensate for poor clinical practice, it places the mother and the babies at risk for complications due to a pregnancy and birth with multiples.
Another factor to consider is the number of cycles performed by a fertility center. If one center performs 1,000 cycles a year with an 80% success rate, you can be confident that the reported success rate accurately reflects that center’s quality. On the other hand, if a fertility center performs just one IVF cycle a year, and that cycle happens to be successful, it may report a 100% success rate. However, that 100% is clearly not an indicator of long-term success with a variety of complex cases.
