The nonspecific radiation damage may affect the male reproductive system, impacting sperm quality. However, reports of azoospermia are rare. Case Presentation: A 26-year-old male patient with papillary thyroid carcinoma underwent cumulative 14.06 GBq 131I ablation therapy postoperatively. Eight months post-treatment, he was diagnosed with azoospermia due to planned conception. After ruling out congenital factors, 131I-related iatrogenic injury was considered. Sperm were detected again in a semen analysis 13 months after treatment completion. Subsequently, successful natural conception occurred, and the spouse delivered a healthy infant vaginally. Conclusion: 131I therapy may induce azoospermia. However, the injury may be reversible. Clinicians should monitor reproductive risks in young patients and conduct follow-up evaluations.<\/jats:p>","DOI":"10.1159\/000552398","type":"journal-article","created":{"date-parts":[[2026,5,16]],"date-time":"2026-05-16T16:00:40Z","timestamp":1778947240000},"page":"882-887","source":"Crossref","is-referenced-by-count":0,"title":["Reversal of Radioiodine-Induced Azoospermia in Thyroid Cancer: A Case Report"],"prefix":"10.1159","volume":"19","author":[{"given":"Haiqing","family":"Deng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,5,16]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213-8587(22)00035-3"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0318605"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1177\/10507256251363120"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2022.0040"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1586\/eem.12.36"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.2007.03081.x"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2006.16.667"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/dey222"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1186\/s12610-015-0024-1"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.281.6254.1527"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s12020-011-9469-y"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2265.2002.t01-1-01545.x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1080\/014850190898746"}],"container-title":["Case Reports in Oncology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000552398","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T16:01:58Z","timestamp":1783440118000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000552398"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,16]]},"references-count":13,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000552398","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.32305857","asserted-by":"subject"}]},"ISSN":["1662-6575"],"issn-type":[{"value":"1662-6575","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,5,16]]}}}
