Introduction: The increasing incidence of malignant diseases that often require gonadotoxic treatment and the tendency to become a parent later in life result in an increased need for fertility preservation.
Aims: The aim of this position statement is to provide and critically appraise evidence on available options for fertility preservation in both pre-pubertal and post-pubertal men and women.
Materials and methods: Literature review and consensus of expert opinion.
Results and conclusions: Fertility preservation should be a priority when treating children or adults of reproductive age with agents that may have hazardous effects on the reproductive system. Gonadotoxicity should be kept at a minimum. If gonadotoxic treatment has to be used, methods of fertility preservation should be discussed, as early as possible.
