背景情况:
- 在改善试管婴儿结果方面,对阳积体 (PGT-A) 的植入前遗传检测至关重要.
- 卵巢刺激方案显著影响卵细胞产量和胚胎发育.
- 了解不同协议对euploidy率的影响对于优化PGT-A周期至关重要.
研究的目的:
- 为了在各种受控卵巢过度刺激方案中比较PGT-A周期中的euploidy率.
- 评估性腺激素释放激素激动剂 (GnRH-a) 长期和短期方案,GnRH-对抗剂 (GnRH-ant) 方案,孕激素原始卵巢刺激和轻度刺激方案对胚胎囊繁殖的影响.
主要方法:

- 在不同的受控卵巢过度刺激方案中分析了3154个活检胚胎.
- 对比每个胚胎活检的euploidy率,每个卵细胞的euploidy率和周期取消率.
主要成果:
- 与GnRH-agonist长期协议 (58.68%) 相比,GnRH-antagonist协议显示每个胚胎活检中的euploidy率较低 (53.26%),而 GnRH-agonist长期协议则较低 (58.68%).
- 多重线性回归证实,GnRH-ant协议与每个胚胎活检中的euploidy率明显较低有关 (β = -0.079,p = 0.011).
- 总淋巴激素剂量,刺激持续时间和卵细胞产量没有显著影响每胚胎活检的euploidy率.
结论:
- 与GnRH-agonist长期协议相比,GnRH-antagonist协议与PGT-A周期中的胚胎细胞积率降低有关.

In Vitro Fertilization
248
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...

Oogenesis
63.7K
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...
