RESUMO
Due to the increasing number of long-term cancer survivors, physicians of all specialties are confronted with the need to prevent side effects of the applied oncologic treatments. In the field of reproductive medicine fertility preservation has gained importance as most oncologic treatments have detrimental immediate or long-term impacts on male and female fertility. The American Society of Clinical Oncology and the American Society for Reproductive Medicine, as well as the recently founded International Society for Fertility Preservation propose several established and investigational options for fertility preservation. This review aims to summarize currently available techniques for fertility preservation and future perspectives in this field, as well as to provide recommendations for patient follow-up after cancer and during pregnancy.
