Fertilization of Frozen Eggs + Embryo Transfer is a fertility treatment for patients who previously preserved unfertilized eggs and are now ready to attempt pregnancy. In this process, frozen eggs are carefully thawed and fertilized in the laboratory using partner or donor sperm. The resulting embryos are cultured under controlled conditions to assess development and quality. Once embryo development is confirmed, one embryo is selected for transfer to the uterus. In many cases, this transfer is performed as a fresh embryo transfer during the same treatment cycle in which fertilization occurs. The procedure includes close monitoring through ultrasounds and hormonal testing to support both embryo development and uterine readiness. This treatment bridges fertility preservation and pregnancy, allowing patients to use eggs frozen at a younger age while benefiting from current reproductive planning. Any additional embryos of suitable quality may be cryopreserved for future use, providing further opportunities for pregnancy if desired.
