Oocyte freezing, also known as oocyte cryopreservation, is the method of preserving a woman’s eggs (oocytes). Eggs are harvested from the ovaries and frozen in an unfertilised condition to be used later. A frozen egg can then be thawed, combined with a sperm and implanted in a woman’s uterus during IVF to facilitate pregnancy in future.
