Single Embryo Transfer (SET)
The Single Embryo Transfer process
Although only a single embryo will be selected for SET, typically, the ovaries are stimulated to release multiple eggs. Some patients may opt for minimal stimulation IVF, a process that limits fertility drug use, or even eliminate ovarian stimulation altogether and proceed with natural cycle IVF.
Once the eggs mature, they are fertilized in the IVF lab and allowed to develop over a 5-day period. At that point, the embryos are evaluated and the healthiest, most viable embryo is chosen for transfer. Any additional embryos may be frozen for future use.
Why Choose Single Embryo Transfer?
SET is a safer alternative to double or multiple embryo transfer for both mother and baby. With the improvement of in vitro fertilization success rates, the American Society of Reproduction Medicine suggests SET be offered to any woman that is considered a good candidate.
Multiple pregnancy increases the likelihood of early labor and premature birth, and women who give birth to multiples are more likely to suffer pregnancy complications such as gestational diabetes and pre-eclampsia.
Multiple birth babies are more likely to require special care in the neonatal intensive care unit and are at an increased risk of permanent disabilities.
Good candidates for single embryo transfer include women 35 and younger who have good quality eggs.
Single Embryo Transfer – IVF Success Rates
Although the pregnancy rate in SET is slightly less than that of two-embryo transfer, when frozen embryos are available for additional transfers, the cumulative IVF pregnancy success rates are similar to that of double embryo transfer.
There are a number of treatment options available for couples undergoing IVF, including single embryo transfer.
