Abstract
In considering gonadal tissue cryopreservation in children about to undergo chemotherapy or radiotherapy for cancer, numerous issues need to be confronted. This relates firstly to a dearth of information available on the subject of children's gonads coupled to ill-defined fertility preservation procedures, technologies and perhaps less well-publicized regulatory, ethical and legal controls. There may be benefits in considering gonadal tissue preservation for children prior to chemotherapy or radiotherapy, in the hope that future technologies can utilize their immature gametes. Whether or not freezing of gonadal tissue is encouraged prior to cancer therapy, there is a growing demand from parents and clinicians for more information to be made available. This paper reviews our current knowledge of children's gonads in terms of physiology and of fertility experience gained after childhood cancer treatment. It further examines the various issues and concerns regarding children's gonadal tissue storage, its potential use, the present law and the demands and pressures under which clinicians find themselves with patients and parents. This information is important for both the counselling process and decision-making when presented with potential fertility issues in paediatric oncology patients.
