Adverse events related to male reproductive toxicity were screened using the MedDRA dictionary. Drug safety signals were detected using ROR, PRR, IC, and EBGM, with reliability enhanced through cross-database validation and dechallenge\/rechallenge analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study included 1,955 FAERS cases and 1,384 from EV, with a median patient age of 35\u00a0years and 37% being reproductive-age males (18\u201344\u00a0years). The median time to event onset was 132\u00a0days, consistent with the spermatogenic cycle. Cross-validation identified 19 high-risk drugs, including hormonal agents (finasteride, dutasteride, testosterone), antineoplastic drugs (bleomycin, vinblastine, hydroxycarbamide), and antidepressants (citalopram, paroxetine). Finasteride satisfied both dechallenge and rechallenge criteria, providing strong evidence for causality. Signals concentrated in three major categories: genitourinary and sex hormones, dermatological preparations, and antineoplastic agents. Stratified analysis showed that both consumer and healthcare professional reports identified 13 high-risk drugs, with high consistency for major drugs (finasteride, testosterone), confirming result robustness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This pharmacovigilance study identified 19 high-risk drugs for male infertility across hormonal agents, antineoplastic drugs, and antidepressants. These findings underscore pre-prescription, risk-stratified fertility counseling for reproductive-age males, prioritizing sperm cryopreservation before chemotherapy and considering it selectively for 5\u03b1-reductase inhibitors, testosterone, or antidepressants.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fphar.2026.1765071","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T06:43:23Z","timestamp":1769669003000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Drug-induced male infertility: a real-world study using FAERS and EudraVigilance databases"],"prefix":"10.3389","volume":"17","author":[{"given":"Zhuozhi","family":"Gong","sequence":"first","affiliation":[{"name":"Department of Andrology, Xiyuan Hospital of China Academy of Chinese Medical Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"He","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Medicine, Southern Medical University","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiujian","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Andrology, Xiyuan Hospital of China Academy of Chinese Medical Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Liu","sequence":"additional","affiliation":[{"name":"China Institute for History of Medicine and Medical Literature, China Academy of Chinese Medical Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengjing","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Andrology, Xiyuan Hospital of China Academy of Chinese Medical Sciences","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"B1","first-page":"168","article-title":"Effects of carbamazepine on semen parameters in men with newly diagnosed epilepsy","volume":"14","author":"Asadi-Pooya","year":"2015","journal-title":"Iran.
