“…The application of ultrasound in the differential diagnosis of thyroid disorders in humans and companion animals has been reported (Cartee et al 1993, Ahuja 2000, Bruneton et al 2002, Wisner et al 2002, American Institute of Ultrasound in Medicine 2003, Reese et al 2005, Brömel et al 2006). Apart from pathological changes, thyroid morphology has been observed to undergo physiological alterations concurrent with changes in the female hormonal environment and dietary iodine intake.…”

Thyroid morphology and function are likely affected by the cyclic hormonal environment during different reproductive events in females. The present study was undertaken to evaluate the variation of thyroid morphology at different reproductive events (anestrus, estrus, lactation, and pregnancy) in a captive group of Indo‐Pacific bottlenose dolphins (Tursiops aduncus) measured using sonography. Sonographic examinations of the thyroid gland and ovaries in nine sexually mature female subjects were performed weekly for 2.5 yr. A generalized linear mixed model was used to estimate the effects of the reproductive events for thyroid volume. Reproductive event was found to be a significant predictor for thyroid volume measurement and significant variation in thyroid volume was found between different reproductive events. A significantly larger thyroid volume in lactating females was observed when compared with estrous and anestrous females, possibly due to the high energy requirements and milk production during lactation. Taken together, thyroid volume variation during different reproductive events in female dolphins should be considered so as to obtain a diagnostically meaningful assessment when conducting routine examinations.
