概括
这次审查发现,没有足够的证据来确定自然周期,激素疗法 (HT) 或排卵诱导周期是否优于冷解胚胎移植 (FET). 需要更多的研究来比较不同FET制备方法的有效性和安全性.
科学领域:
- 生殖医学 生殖医学
- 在体外受精 (IVF)
- 内分泌学 在内分泌学.
背景情况:
- 冷解胚胎移植 (FET) 是辅助生殖技术的关键组成部分,旨在提高累积怀孕率.
- 对于FET,存在各种循环方案,包括自然循环,激素疗法 (HT) 循环和排卵诱导循环,每个都有不同的准备方案.
- 这一审查是之前的Cochrane分析的更新,反映了FET循环管理的不断变化的格局.
研究的目的:
- 系统地比较自然周期FET,HT FET和排卵诱导FET疗法的有效性和安全性.
- 分析和比较这些FET循环方案中的不同亚型.
- 为优化FET准备策略提供基于证据的指导.
主要方法:
- 对多个数据库 (Cochrane妇科和生育专业注册,CENTRAL,MEDLINE,Embase) 和试验注册进行了全面的搜索.
- 包括随机对照试验 (RCT),比较不同的周期方案和FET的子宫内膜制备方法.
- 评估的主要结果包括活产率和流产率,采用标准的柯克伦方法程序.
主要成果:
- 分析了32项涉及6352名女性的RCT,证据确定性从中等到非常低.
- 自然周期FET,HT FET (有或没有GnRHa抑制) 和修改的自然周期 (具有HCG触发) 之间的比较显示了活产,流产和多胎妊娠率的不确定的差异.
- 局限性包括对结果和方法的报道不足,以及由于事件率低而导致的不准确性,阻碍了最终的结论.
结论:
- 目前的证据基础在很大程度上是低确定性,在比较中具有广泛的置信区间.
- 没有足够的证据来最终得出结论,任何特定的FET循环方案比其他更有效或更安全.
- 需要进一步进行高质量的研究,以澄清FET中的子宫内膜制备的最佳方法.

In Vitro Fertilization
234
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...

Meiosis II
183.2K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...
