概括
孕激素主导的卵巢刺激 (PPOS) 降低了LH过早激增,但与GnRH对抗剂协议相比,与较低的活产率有关. 这表明对卵细胞质量的潜在影响,需要进一步研究生育治疗.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 在体外受精 (IVF)
- 基因组学就是基因组学.
背景情况:
- 卵巢刺激协议对于试管婴儿的成功至关重要.
- 孕激素主导的卵巢刺激 (PPOS) 和性腺激素释放激素 (GnRH) 反对者协议是常见的方法.
- 将它们的生殖结果和潜在机制进行比较对于优化患者护理至关重要.
研究的目的:
- 为了比较PPOS的生殖结果与第一轮试管婴儿周期中的GnRH抗剂协议.
- 通过单细胞RNA测序 (scRNA-seq) 来研究两种协议之间的颗粒细胞中潜在的分子差异.
主要方法:
- 对907名接受第一次试管婴儿周期的患者进行了回顾性队列研究.
- 对PPOS (n=299) 和GnRH抗剂 (n=608) 协议的比较.
- 对临床数据应用的治疗权重的反向概率 (IPTW).
- 从16名患者 (每组8人) 的壁面颗粒细胞 (mGC) scRNA-seq分析.
主要成果:
- 与GnRH对抗剂协议相比,PPOS显著降低了LH过早激增率 (3.1%对20.1%).
- 活产率在PPOS组较低 (31.5%),与GnRH抗组相比 (42.3%).
- scRNA-seq揭示了PPOS组的mGC中12个线粒体DNA (mtDNA) 基因的更高表达.
结论:
- 虽然PPOS有效地抑制LH激增,但与GnRH抗剂协议相比,它与降低活产率有关.
- 在PPOS周期中的颗粒细胞中mtDNA基因表达的升高可能表明卵细胞质量受损.

Oogenesis
64.5K
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...

Hormonal Control of the Ovarian Cycle
3.5K
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...
