[Cancer and the right to motherhood]. / Cancer et droit à la maternité.

As a result of advances in the field of oncology, cancer survival rate has improved at the cost of sequelae in terms of fertility with a possible loss of ovarian function in girls. To alleviate the consequences of this iatrogenic menopause, various options are available. Cryopreservation of ovarian cortex, allowing the preservation of immature cells, is one of the best solutions and gave birth to 24 children worlwide. These results make it legitimate to propose freezing ovarian tissue for pediatric patients or young adult women undergoing potentially sterilizing treatment. The decision has to be discussed with the patient and/or his legal representative, the oncologist and gynecologist.
