In the cases where sperm is retrieved by surgical methods such as TESA, TESE, or micro TESE, if adequate volume of sperms is available, the testicular tissue can be frozen to be used for other treatments and to eliminate the need for another operation in consideration of possible future attempts.
In addition, sperm sample can be collected and frozen in advance of the treatment for patients with who chemotherapy or radiotherapy is planned, or for persons who have difficulty in providing their sperm.
Frozen tissue or sperm samples can be stored for up to 3 years in special tanks with -196 ºC containing liquid nitrogen. Patient’s written consent is required for freezing procedure.
