MyIniczenko (25316250) Veterinary Anaesthesiology and Intensive Care gonad ovariectomy ovary shark stingray surgery Introduction<p>Reproductive disease in female elasmobranchs has been increasingly reported in the literature, though there are limited descriptions of therapeutic intervention.</p>Methods<p>This retrospective case series details the surgical management of 20 female elasmobranchs representing nine species. Data for this study were collected from the medical records and necropsy reports of elasmobranchs at six separate zoos and aquaria.</p>Results<p>All animals presented with ovarian or uterine abnormalities, including ovarian enlargement (either due to the presence of cysts and/or chronic follicle retention), yolk coelomitis, and excess uterine fluid. Medical management, primarily hormonal and antibiotic therapy, failed to resolve clinical signs in these cases, and the patients were unlikely to survive long-term. All animals underwent complete or partial unilateral ovariectomy (22 procedures total). Surgical approach, anesthetic protocols, and intraoperative treatments varied by species and institution. Post-operative complications were common, particularly hyporexia, dehiscence, and persistent bacterial coelomitis (when already present prior to surgery). Two Chilean round rays (Urotrygon chilensis) required a second ovariectomy after a functional contralateral ovary developed post-unilateral ovariectomy. In this group, 32% of the patients experienced post-operative mortality directly due to surgical or post-surgical complications; 18% died post-operatively due to pre-existing conditions or systemic compromise. However, this was improved with balanced anesthetic protocols and more aggressive peri-procedural supportive care based on the authors’ experience.</p>Discussion<p>In successful procedures, ovariectomy led to the resolution of clinical signs, demonstrating that ovariectomy is a viable therapeutic option for reproductive disease in elasmobranchs, though early intervention, post-operative monitoring, and supportive care are recommended.</p> 2026-10-05T14:57:05Z Dataset Dataset 10.3389/fvets.2026.1958413.s001 https://figshare.com/articles/dataset/Supplementary_file_1_Surgical_management_of_reproductive_disease_in_aquarium_managed_female_elasmobranchs_docx/34070511 CC BY 4.0
