概括
大多数异常的马行为与卵巢激素无关,这挑战了常见的假设. 马的行为是个例外,显示了与激素水平升高的联系.
科学领域:
- 马类繁殖的繁殖方式
- 兽医内分泌学 兽医内分泌学
- 动物行为 动物行为
背景情况:
- 异常的马行为经常归因于卵巢异常.
- 这种假设缺乏全面的科学验证.
研究的目的:
- 为了调查异常马匹行为的发生率.
- 评估这些行为与卵巢激素度之间的关联,特别是与颗粒细胞瘤 (GCTs) 相关.
主要方法:
- 对2914个与行为问题相关的荷尔蒙特征样本的回顾性分析.
- 测试度,抗穆勒尔激素 (AMH),抑制剂和抑制剂-B的评估度.
- 使用奇平方测试来确定行为和荷尔蒙水平之间的关联.
主要成果:
- 86%的病例没有显示类似于GCT的激素度.
- 马的行为与升的丸激素,AMH,抑制素和抑制素-B显著相关.
- 侵略性,雌性行为和其他异常行为与激素水平的增加没有显著关联.
结论:
- 异常的母马行为,除了马的行为外,通常与卵巢激素的升高无关.
- 这项研究挑战了常见的假设,将卵巢异常与最不理想的马匹行为联系起来.
- 卵巢激素水平不太可能是马匹大多数行为问题的主要原因.

01:30Hormonal Control of the Ovarian Cycle
592
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
