Fertility preservation in the process of storing eggs, sperm, embryos and reproductive tissue so that a person can use them in the future to have their own biological children. Fertility preservation can be used for people with a specific, imminent and significant risk to fertility such as:
- Patients with newly diagnosed or ongoing cancer treatment
- Use of chemicals on other treatments (e.g. for some rheumatological and haematological treatments).
- Patients undergoing gender reassignment
- Front line armed forces
Some people may opt for fertility preservation to delay having children.
