循環中雌激素與輕度全身性脫水對雌性大鼠超聲波發聲的影響

// Impact of Circulating Estrogen and Mild Systemic Dehydration on Ultrasonic Vocalizations in Female Rats

本研究探討雌激素降低、雌二醇補充及輕度脫水對女性大鼠超音波叫聲（USVs）的影響｜結果顯示，雌激素缺乏使USVs持續時間與強度下降，脫水則縮小頻率範圍並根據激素狀態調整聲音特徵｜研究提供激素與水分互動影響喉部功能的臨床前模型，助於理解相關生理機制。

// This study examined how reduced estrogen, estradiol replacement, and mild dehydration affect ultrasonic vocalizations (USVs) in female rats. Rats were grouped by hormonal and hydration status, with USVs measured before and after treatments. Results showed that estrogen loss reduced USV duration and power, while dehydration narrowed frequency range and affected USV characteristics depending on hormonal state. The findings suggest that estrogen and hydration subtly and interactively influence vocal patterns, providing a preclinical model for hormone-hydration effects on laryngeal function.
