Egg, Embryo, Testis Biopsy and Semen Cryopreservation

Cryopreservation involves the careful freezing and storage of transferred, good quality eggs, embryos and semen/sperm. The freezing technique used at our unit is known as Vitrification (fast freezing) and has a 98% survival rate once the embryos are thawed. In case the patients cycle is not successful or they decide to have another child years later, these embryos may be unfrozen (thawed). Only the healthiest embryos are frozen.

Semen is also frozen and stored for later use in cases such as prior to vasectomy or any cancer treatment (eg.: chemotherapy and/or radiation) where fertility can be influenced due to the drugs administered.
