Should sperm be stored before chemotherapy?
Sperm storage should be discussed before chemotherapy when treatment may affect fertility and future parenthood is desired or undecided. Risks differ by medicines, doses and health circumstances. Early consultation matters, but cancer treatment should not be delayed independently.

Why discuss it before the first dose?
Sperm production may be affected temporarily or permanently, and recovery cannot be predicted precisely for every individual. Oncology and fertility teams coordinate collection, assessment and storage when appropriate and feasible within the available time.
If a sample cannot be provided
Tell the team early so suitable options can be explored, sometimes requiring specialist assessment. Options differ before puberty; experimental testicular-tissue preservation is not equivalent to established mature-sperm storage.
What are its limitations?
Freezing does not guarantee pregnancy and assisted fertility treatment may be needed. Discuss costs, storage, consent and follow-up. Pregnancy may remain possible during treatment; follow oncology guidance on contraception and when to try conceiving afterwards.
