Women might be able to store eggs prior to undergoing cancer therapy in new improved methods of cryopreservation of their eggs. Previously, eggs could be frozen, but ice crystals would form inside the egg, destroying them when thawed. Vitrification is the rapid freezing of the egg that happens so quickly ice crystals fail to form and the eggs retain their viability. When women are exposed to chemotherapy and radiation therapy for treatment of such cancers as breast or pelvic cancer, there is a high risk that the treatment can also affect their reproductive organs, causing infertility. With cryopreservation and assisted reproductive technology, particularly intracytoplasmic sperm injection (ICSI), women should be able to retain their right to conceive after cancer therapy. Men can also benefit from the technology with freezing sperm.
