科学领域:
- 兽医繁殖 兽医繁殖 兽医繁殖
- 动物科学动物科学
- 实验室诊断 实验室诊断 实验室诊断
背景情况:
- 精液分析对于马繁殖管理和临床实践至关重要.
- 对精子运动性的客观评估可以提高分析精度.
- 计算机辅助精子分析 (CASA) 系统提供客观的运动性评估.
研究的目的:
- 为了验证便携式CASA系统Androscope,用于马精液分析.
- 将Androscope的性能与黄金标准CASA系统 (IVOS II) 的性能进行比较.
主要方法:
- 使用Androscope和IVOS II CASA系统评估了新鲜/冷却和冷的马精液样本.
- 比较精子运动率估计,包括运动精子的百分比和逐渐正常的精子.
- 评估精子运动参数,如速度,ALH和BCF.
主要成果:
- 在Androscope和IVOS II之间发现了强烈的正相关性 (R2=0.31到0.83),用于所有运动率估计.
- 与IVOS II相比,Androscope显示了更低的运动精子百分比 (平均差异: -4.2%),但与IVOS II相比,具有相似的逐渐正常的精子百分比.
- 在精子动力学 (速度,ALH,BCF) 中注意到系统差异,可能是由于Androscope的视频采集率较慢 (45 Hz与60 Hz).
结论:
- 安卓Scope系统为马精子运动参数提供了精确的结果.

Sperm Transport
511
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Sperm Structure and Semen Composition
916
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...
