概括
这项研究开发了一个模型来优化IVF/ICSI中的淋巴激素起始剂量,有效预测OHSS等治疗风险,但对活产预测的准确性有限.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 在体外受精过程中受精.
- 临床试验分析
背景情况:
- 卵巢对淋巴激素的反应有所不同,这影响了活产率和IVF/ICSI的治疗风险.
- 卵巢储备测试 (ORT) 如AMH,AFC和bFSH用于指导淋巴激素剂量.
- 个性化淋巴激素剂量可能会降低像OHSS这样的风险,而不会影响活产率.
研究的目的:
- 开发和验证一个预测模型,用于在IVF/ICSI中选择最佳的淋巴激素起始剂量.
- 该模型旨在尽量减少治疗风险,同时保持活产率.
- 使用个人患者数据元分析 (IPD-MA) 进行通用模型开发.
主要方法:
- 系统地搜索 MEDLINE,EMBASE 和 CRSO 的相关 RCT,直到 2022 年 7 月.
- 包括RCT比较IVF/ICSI中的淋巴激素剂量与报告的ORT和活产/怀孕结果.
- 将通用线性混合多层模型应用于IPD,用于预测器选择和模型开发.
主要成果:
- 分析包括2907名女性 (在排除39岁以上的女性后).
- 一个活产预测模型 (AUC=0.557) 包括年龄,剂量,BMI,AFC,IVF/ICSI和AMH.
- 综合治疗风险的模型 (AUC=0.769) 包括年龄,剂量,AMH和bFSH或GnRH类似物.
结论:
- 开发的模型充分预测了与淋巴激素起始剂量相关的治疗风险 (例如,OHSS).
- 该模型在根据FSH起始剂量调整预测活产率方面表现不佳.
- 这种剂量选择模型有助于选择最佳的淋巴激素起始剂量,以减少风险和潜在的成本.

In Vitro Fertilization
214
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Hormonal Control of the Ovarian Cycle
406
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...
