Fresh vs. Frozen Embryo Transfers

Reading Time: 2 minutes

When undergoing in vitro fertilization (IVF), one of the key decisions you’ll face is whether to proceed with a fresh embryo transfer or a frozen embryo transfer (FET). Both approaches have unique advantages, and understanding the differences can help you and your fertility specialist determine the best path for your journey to parenthood.

What is a Fresh Embryo Transfer?

A fresh embryo transfer occurs during the same cycle in which your eggs are retrieved and fertilized. After the embryos develop for several days in the lab, one is selected and transferred into the uterus. The remaining high-quality embryos can be frozen for future use.

Benefits of Fresh Embryo Transfers
  • Shorter timeline: No need to wait for a future cycle—transfer happens within days of egg retrieval.
  • Fewer medications: Less medication is required compared to preparing for a frozen transfer.

Potential Drawbacks
  • Hormonal fluctuations: Your body is still recovering from ovarian stimulation, which may affect implantation.
  • Risk of ovarian hyperstimulation syndrome (OHSS): If you have a high response to fertility medications, a fresh transfer may not be recommended.

What is a Frozen Embryo Transfer (FET)?

A frozen embryo transfer involves freezing viable embryos from a previous IVF cycle and transferring one at a later date. This allows your body to recover from ovarian stimulation before implantation.

Benefits of Frozen Embryo Transfers
  • Higher success rates: Research shows that FETs may have improved pregnancy rates compared to fresh transfers, particularly in women with high estrogen levels during stimulation.
  • Better uterine environment: The uterus can be more receptive when hormones are at natural levels.
  • Flexibility: Couples can plan the transfer for a time that works best for them.

Potential Drawbacks
  • Longer wait time: You’ll need to wait until a future cycle to complete your embryo transfer.
  • Additional medications: Preparing for a frozen cycle may require hormone therapy.

Which Option is Best for You?

The choice between a fresh and frozen embryo transfer depends on several factors, including your medical history, hormone levels, and personal preferences. Our fertility specialists at RPSD will guide you through the decision-making process to ensure the best outcome for your treatment.
