SC-B913, Testicular tissue cryopreservation (TTC) for fertility preservation in male patients facing infertility-causing diseases or treatment regimens

SC-B913: TTC Study

What is the goal of the study?

The “Testicular Tissue Cryopreservation” study is open to patients facing disease or treatment regimens that could lead to infertility. The study will provide research tissue to hopefully 1) optimize techniques for cryopreservation of testicular cells, including spermatogonial stem cells, from patients at high risk for infertility due to disease or prior to the initiation of therapy. Efficacy of cryopreservation techniques will be determined. 2) Determine presence and number of germ cells in the patients’ testicular tissue. 3) Develop methods to enrich spermatogonial stem cells and remove malignant contamination from testicular tissue. 4) Develop stem cell based therapeutics to restore fertility.

Who can participate in the study?
