Long tern storage is primarily for the storage of gametes and/or embryos prior to chemo or radiotherapy for cancer. We will be pleased to provide specific information on the length of storage permitted legally in your case. This can be quite a long storage period and up to your 55th birthday or for a total of 55 years. However this does not mean that the trust will be able to keep the sperm for this length of time. The duration of storage is agreed with yourself after discussion with your specialist, bearing in minds your reproductive intentions, how your fertility will be affected by chemo or radio therapy and your prognosis.
