As a result of advances in oncologic treatment, a growing number of women diagnosed with cancer may envisage cure. Young women diagnosed with cancer often have a desire to fall pregnant in the future or may even be diagnosed with cancer in the process of family planning. The potential gonadotoxic effect of certain chemotherapeutic agents is well described. Therefore, it is essential that all women concerned about their fertility receive counselling from a reproductive medicine specialist to discuss the fertility preservation options. Currently, ovarian stimulation with cryopreservation of oocytes or fertilized oocytes is the treatment of choice. However, other options such as in vitro maturation or ovarian tissue cryopreservation should be discussed if ovarian stimulation is contraindicated.
