Abstract: A method of preserving functionality of an organ. The method includes removing a whole organ and associated vasculature, cryo-preserving the whole organ, allowing a period of time to elapse, thawing the whole organ including vasculature and introducing the whole organ into a recipient so that the organ is supplied with blood by vasculature belonging to the recipient. Further disclosed is a method of preserving fertility of a patient undergoing a treatment expected to cause sterility. The method include removing a whole gonadal organ from the patient, cryo-preserving the whole gonadal organ, conducting the treatment and waiting for an effect thereof to subside, thawing the whole gonadal organ and introducing the whole gonadal organ where it is supplied with blood by the vasculature system of the patient.
