Abstract
The response of the pituitary-testicular axis to LH-RH infusion was investigated in rams from birth to sexual maturity. During early postnatal life ram lambs were responsive to LH-RH stimulation and heightened pituitary sensitivity was observed in rams aged 2-3 months. It is suggested that a change in sensitivity of the pituitary-testicular axis occurs at this time and perhaps represents the time of initiation of the pubertal process.
摘要
研究了从出生到性成熟的公羊垂体-睾丸轴对促黄体生成素释放激素（LH-RH）输注的反应。在出生后的早期生活中，公羊羔羊对LH-RH刺激有反应，并且在2-3个月大的公羊中观察到垂体敏感性增强。有人认为，此时垂体-睾丸轴的敏感性发生了变化，这可能代表了青春期过程开始的时间。
