Embryofrysning
Embryofrysning, or cryopreservation of embryos, is a medical procedure used in assisted reproductive technology to preserve embryos created during in vitro fertilization (IVF) or other ART procedures for later use. Freezing embryos allows subsequent pregnancy attempts without repeating ovarian stimulation and egg retrieval.
During the process, after ovarian stimulation and fertilization, surplus viable embryos may be selected for freezing.
Frozen embryo transfer (FET) cycles use thawed embryos to establish pregnancy. Freezing offers flexibility, helps maximize
Safety and considerations: Most studies report no significant increase in congenital anomalies with frozen transfers compared
Storage and limits: Embryos may be stored for many years; there is no fixed biological expiry, but
