Testicular tissue banking may be option to preserve fertility

Boys diagnosed with cancer who have reached puberty currently have an opportunity to preserve their fertility: before undergoing cancer treatment, they may have their semen frozen and preserved in sperm banks. Younger boys, however, do not produce sperm, although their testicular tissue contains young cells that will eventually become sperm.

Now The Children’s Hospital of Philadelphia is offering a unique option to those boys: from infants up to younger adolescents, at-risk boys can have a tiny portion of their testis removed and frozen for their potential future use. Researchers are also using part of the tissue to investigate ways to help the immature cells in the testes to develop into useable sperm.
