概括
这项研究发现,在卵泡阶段刺激 (FPS) 和黄细胞阶段刺激 (LPS) 之间的卵细胞产量没有差异. 在这组患者中,叶阶段刺激与卵泡阶段刺激相比,没有改善卵细胞检索.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 在体外受精 (IVF)
- 卵巢刺激协议 卵巢刺激协议
背景情况:
- 在试管婴儿中反应不佳的患者往往具有有限的卵细胞产量.
- 毛囊阶段刺激 (FPS) 和黄质阶段刺激 (LPS) 是两种不同的卵巢诱导协议.
- 与FPS相比,LPS在特定患者群体中的有效性仍然是一个研究领域.
研究的目的:
- 为了比较FPS和LPS在被归类为低于最佳反应的患者中检索的卵细胞数量.
- 评估二次结果,如第二阶段和受精卵细胞,FSH剂量和刺激持续时间.
主要方法:
- 一项前性随机交叉临床试验,涉及41名符合POSEIDON标准 (1b/2b) 的患者.
- 参与者接受了两次非连续的卵巢刺激,随机分配开始在卵泡或质阶段.
- 卵细胞产量 (积卵细胞复合体) 是主要的结果衡量标准.
主要成果:
- 在FPS和LPS组之间检索的累积卵细胞复合体的平均数量没有显著差异 (7.5 ± 4.6与7.0 ± 4.1).
- 同样,在两个刺激阶段 (5.4 ± 3.6与5.2 ± 2.8) 之间,获取的第二阶段卵子细胞的平均数量是可比的.
- 所有的二次结果测量也显示,FPS和LPS之间没有显著差异.
结论:
- 与卵泡阶段刺激相比,当周期在时间上相隔时,质阶段刺激不会提高低最佳响应者的卵细胞产量.
- 与FPS相比,LPS发病的时间似乎没有影响这个队列中的卵细胞检索结果.
- 目前的证据表明,FPS和LPS在非最佳反应者中产生类似的卵细胞数量.

Ovarian Cycle
1.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Hormonal Control of the Ovarian Cycle
518
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...
