Abstract
Multimodality treatments have increased the survival of cancer patients in recent years. With cure the quality of life also should be taken into consideration. Maintenance of the reproductive capacity is of great concern to many young patients. Until now the cause of sterility was attributed to the long-term side effects of treatment when recovery could not be predicted. Pre-treatment sperm banking is advised routinely for many of these patients. Our own observation as well as a few other reports show that cancer itself seems to have an adverse effect on fertility before any form of treatment. As assessed by semen quality the majority of our patients were subfertile when first seen. Hence, sperm banking may be a poor guarantee for future reproduction in these patients.
