You may think that cryopreserving testicle tissue is kind of a stretch- but many cancer patients undergoing treatments don’t have options when it comes to preserving fertility. Doctors can cryopreserve sperm if the patient has already reached puberty, but for young boys, that’s not an option.
By cryopreserving testicle tissue, researchers are able to thaw tissue at a later date and induce the production of sperm. This research was carried out in mice, and through artificial insemination, eight healthy offspring were produced! Amazingly, thawed tissue was able to produce sperm just as well as unfrozen tissue.
There’s still some work to be done before this research can be translated into humans. But as more and more pediatric cancer patients are being successfully cured of their diseases, this research could mean life-changing, long-term fertility options. Read more about it here:
