Embryo Cryopreservation

If transfer in the current cycle is unsuitable due to the risk of ovarian hyperstimulation syndrome, health conditions, or personal factors, all embryos may first be frozen (Freeze-all). Transfer can be performed later at an appropriate time, improving treatment safety and success rates.

If good-quality embryos remain after transfer, they can be cryopreserved and thawed for a future transfer, increasing future chances of pregnancy.

Under Taiwan's Assisted Reproduction Act, embryos may be cryopreserved for up to 10 years.
