title: [Is the cryopreservation of sperm of young tumor patients reasonable?].
abstract: Operation, retroperitoneal lymphadenectomy, irradiation and chemotherapy may reduce the fertility potential of young male patients suffering from a malignant tumour. Prediction of the reversibility is difficult. Cryopreservation is a possibility to maintain the fertility of such patients. Unfortunately, the quality of the sperm is often reduced beforehand. The sperm motility is noticeably reduced by the freezing process. But the sperm preservation may help to reduce the psychological stress of the patients, thus improving their quality of life. Therefore, we recommend the use of the method liberally, although only few patients will make use of their sperm later. There has been no known teratogenicity to date. We report on our own experience with cryopreservation in 39 patients.
