概括
在冷胚胎移植 (FET) 周期期间,胚胎在移植导管中的保留与生化怀孕,临床怀孕和活产的可能性较低有关. 这一发现突出了在辅助生殖中对生殖成功的潜在影响.
科学领域:
- 生殖医学 生殖医学
- 辅助生殖技术 辅助生殖技术
- 胚胎学 胚胎学
背景情况:
- 胚胎在移植导管中的保留是冷胚胎移植 (FET) 周期中罕见的事件.
- 这种现象对怀孕结果的影响仍然不完全理解.
研究的目的:
- 调查胚胎在输送导管中保留对接受FET的妇女各种妊娠结果的影响.
- 分析胚胎保留与活产,生化妊娠,临床妊娠,流产和宫外妊娠之间的关联.
主要方法:
- 追溯队列研究涉及39,118名从2016年1月到2022年12月接受FET周期的女性.
- 对照组 (n=38,933) 与胚胎保留组 (n=185) 的比较,使用倾向得分匹配 (PSM).
- 主要结局是活产 (LB);次要结局包括生化妊娠,临床妊娠 (CP),流产和宫外妊娠.
主要成果:
- 胚胎保留发生在FET周期的0.47%中.
- 在PSM之后,与对照组相比,胚胎保留组显示生化妊娠的可能性降低 (OR 0.83),CP (OR 0.81),和LB (OR 0.80).
- 在胚胎保留组中观察到更高的出生体重,在流产,宫外妊娠,剖腹产或妊娠年龄方面没有显著差异.
结论:
- 胚胎保留在输送导管中与生物化学怀孕,临床怀孕和活产在FET周期的可能性降低有关.
- 虽然与较低的怀孕成功率有关,但胚胎保留并没有增加流产或宫外妊娠的风险,并且与更高的出生体重有关.

In Vitro Fertilization
230
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...
