Childhood cancer survivors are at an increased risk of infertility in later life, finds a research.

Infertility was suspected in 30% of them. In one subgroup 23% of the responders stated that they and their partner had failed to conceive a child despite at least 24 months of unprotected intercourse, thus fulfilling the World Health Organization's definition of infertility.
In a second investigation, the Berlin hormone testing and sperm analysis study, 201 survivors of childhood cancer consented to fertility testing. Infertility was suspected in a quarter of them.
On the basis of these findings, the authors conclude that patients and/or their parents should be informed about possible fertility-preserving measures before commencement of treatment.
