Preservation of ovarian function.

In the last years, advances in diagnosis and new treatments of cancer patient have increased the life expectancy of children, adolescent and women with cancer. Unfortunately, the ovaries are very sensitive to chemio-radiotherapy that may induce the loss of ovarian function and fertility with consequent premature ovarian failure. The different cryopreservation options available for fertility preservation in cancer patients are embryo cryopreservation, oocyte cryopreservation and ovarian tissue cryopreservation. The choice depends on different parameters: the type and timing of cancer treatment, the type of disease, the patient's age. The advances in reproductive technology have made fertility preservation a real possibility for patients whether they are girls or young women whose gonadal function is threatened by natural premature menopause, or by cancer therapy or surgical sterilisation.
