Testicular tissue cryopreserved before puberty was shown to be able to produce viable sperm after being re-transplanted into the original patient, who is now an adult. The findings offer hope to men left infertile after childhood cancer treatments.
Professor Rod Mitchell, a paediatric endocrinologist at the Centre for Reproductive Health at University of Edinburgh who is conducting similar research, said to the Guardian: 'There is now proof of principle in humans that this approach is going to work, which is amazing.'
Professor Mitchell also commented on this study, which is yet to be published in a peer-reviewed journal, at a recent PET event on male infertility (see BioNews 1333 and 1123).
