Biochemical and Hepatic Determinants of Reproductive Failure in Reptiles: A Review of Dystocia Pathophysiology and Management.

Dystocia represents a multifactorial and clinically significant reproductive disorder affecting a broad spectrum of reptilian species. Commonly resulting from prolonged vitellogenesis, endocrine disruption, or hepatic lipidosis, dystocia is often exacerbated by suboptimal husbandry or concurrent disease. This review critically evaluates the etiology, diagnostic criteria, and therapeutic interventions associated with this condition. Emphasis is placed on the interplay between metabolic exhaustion and hepatic compromise, which may lower the threshold for surgical intervention. The efficacy and limitations of oxytocin-based protocols are discussed in the context of hormonal receptor variability and response attenuation. Advanced diagnostic modalities, including ultrasonography, radiography/CT, and biochemical profiling, are reviewed for their utility in case stratification. Finally, surgical management options are considered for cases refractory to medical treatment, with attention paid to timing, anesthetic risk, and post-operative care. Collectively, this synthesis aims to inform evidence-based clinical decision-making and promote improved standards of care in reptile reproductive medicine.
