While IVF is rarely anyone’s first choice to have a baby, it does have some advantages. One of them is greater control over your fertility. Because embryos are conceived in the laboratory, you and your fertility specialist can make decisions about how best to use them, including whether you want your physician to transfer fresh vs. frozen embryos to achieve pregnancy.
In the past, an IVF cycle typically ended with the transfer of a fresh embryo. Any remaining embryos were frozen. Today, it’s increasingly common to wait a month or two, and then do a frozen embryo transfer (FET). Is one option better than the other? At our New York fertility center, the decision depends on several factors.
Some research suggests that IVF outcomes may be improved with frozen embryo transfer, compared with fresh transfer. Scientists believe one reason may be that FET allows for a closer simulation of natural conditions in the woman’s body.
For some women, other factors also come into play when using fresh vs. frozen embryos.
Freezing embryos is not thought to have a negative impact on their quality, or on the healthy development of a baby. In fact, vitrification techniques have become so advanced that embryos can be stored for decades before being thawed and transferred to grow into healthy children.
On the flip side, freezing and storing embryos for later transfer can increase the cost of an IVF cycle, which is an important consideration for many women and couples.
The decision to transfer fresh vs. frozen embryos is up to you and your fertility specialist, and depends on the specific factors surrounding your unique situation.
