Short answer
Several possible studiesNo clear answer.
More than one paper fits the article's details, and none fits well enough to single out. Checking claims against the wrong study would be worse than not checking them at all.
Checked against the study summary. The full text wasn't available, so some details couldn't be settled either way.

Claim 1 of 7Not checkedDoctors in Edinburgh have performed a pioneering procedure to transplant a young man's testicular tissue that was frozen before he underwent chemotherapy, in a potential breakthrough for male fertility preservation.View evidenceHide evidence

NewsLink could not identify one source study, so this claim was not compared against a paper.
Claim 7 of 7Not checkedThe article says research in non-human primates showed that testicular tissue frozen before sterilizing chemotherapy could be transplanted back successfully and that mature sperm from the transplanted tissue were later used in assisted reproduction, resulting in a live birth.View evidenceHide evidence
