Freezing testicle tissue in mice offers fertility hope
Children are increasingly surviving childhood cancers, but the treatment leaves many of them unable to have children of their own. Older boys who have reached puberty can have their sperm frozen and banked; younger boys haven't had that option.
Now, a new study in mice suggests it may someday be possible for these younger boys to have a small amount of tissue from their testicles preserved before treatment, defrosted years later and used to generate sperm cells.
