Abstract
Numerous studies have evaluated changes in time of testicular development in birds by exploratory laparotomy or post-mortem autopsy. The invasive nature of these approaches has obviously limited the frequency at which these measures can be collected. We demonstrate here that accurate assessment of gonadal size can be reliably and repeatedly obtained by computer-assisted X-ray tomography (CT scans). This approach provides images of the testes in the three orthogonal planes that allow measuring either the largest diameter or even the volume of the testes, providing results that match those obtained by surgical approaches.
摘要
许多研究通过探索性剖腹手术或死后尸检来评估鸟类睾丸发育时间的变化。这些方法的侵入性显然限制了这些措施可以采集的频率。我们在这里证明，计算机辅助 X 射线断层扫描（CT 扫描）可以可靠且反复地准确评估睾丸大小。这种方法提供了睾丸在三个正交平面的图像，允许测量睾丸的最大直径甚至体积，提供的结果与手术方法获得的结果相匹配。
