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>
