概括
人工卵细胞激活 (AOA) 在以前胚胎发育不佳的患者中没有改善胚胎细胞发育率. 没有AOA的常规细胞内质精子注射 (ICSI) 显示了更好的胚胎细胞率,这表明AOA可能对这个患者群体没有好处.
科学领域:
- 生殖医学 生殖医学
- 胚胎学 胚胎学
- 在体外受精过程中受精.
背景情况:
- 生理性卵细胞激活依赖于精子-卵细胞协同作用,用于振荡.
- 人工卵细胞激活 (AOA) 为受精失败提供了替代方案,但它对胚胎细胞率的影响仍在争论中.
- 上一篇 在体外受精 - 内细胞质精子注射 (IVF-ICSI) 试验中,胚胎细胞发育不佳或不发育,表明需要改进协议.
研究的目的:
- 调查AOA对IVF-ICSI后血母细胞发育不良或不发育的病史患者的血母细胞发育率的影响.
- 为了比较ICSI循环与AOA和传统ICSI循环之间的胚胎细胞发育率.
- 评估二次结果,包括与AOA相关的受精和怀孕率.
主要方法:
- 一项回顾性队列研究对54对夫妇进行了比较,其中54对夫妇的胚胎细胞发育不足最佳水平.
- 22对夫妇在他们的第二个周期中接受了ICSI与AOA (离子体暴露).
- 32对夫妇在他们的第二个周期中接受了没有AOA的常规ICSI,作为对照.
主要成果:
- 与之前的常规ICSI相比,AOA后的囊胚细胞率并没有显著上升 (48%对29%,p=0.19).
- 与对照组相比,没有AOA的常规ICSI显示了明显更高的囊胚细胞率 (48%对24%,p=0.04).
- 受精率和没有可使用胚胎的患者比例在两组之间没有显著差异.
结论:
- 目前的证据并不强烈支持AOA克服受损的胚胎发育和改善胚胎细胞发育率.
- 最好将AOA保留在受精失败的情况下,以提高受精结果.
- 优化实验室条件和卵巢刺激可能比AOA在选定的患者群体中更有效地改善胚芽细胞率.

Oogenesis
69.1K
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...

In Vitro Fertilization

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...
