[Cancer and fecundity].
The overall increase in relative survival rates of adult and childhood cancer patients is related to improved chemotherapy and radiotherapy treatment protocols. However, this success is tempered by gonadotoxic effects and uterine damage. The reduced fertility and possible premature menopause can have a profound impact on patients self-esteem and quality of life. Consequently, preservation of fertility or treatments to protect the ovarian function, become a more relevant issue. Advances in assisted reproduction techniques have focused on the following: embryo cryopreservation which is restricted by time and constrains such as, sexual maturity and the presence of a stable partner. Cryopreservation of immature ovarian tissue, the most promising option, with restoration of natural fertility following auto-transplantation or maturation of oocytes in vitro in combination with assisted reproduction.
