概括
对于38岁以下有足够胚胎的女性,转移一个新鲜的裂变阶段胚胎和一个冷的胚胎胚胎可以提高活产率并减少多胎相比,转移两个新鲜的裂变阶段胚胎.
科学领域:
- 生殖医学 生殖医学
- 在体外受精 (IVF)
- 胚胎移植策略 胚胎移植策略
背景情况:
- 单个胚胎移植 (SET) 策略旨在提高活产率,同时减少多胎妊娠.
- 累积活产率与重复的SETs可以与双重胚胎移植 (DET) 率相匹配.
- 只有有限的证据可以比较新鲜的DET与新鲜的SET,其次是冷的胚芽细胞SET.
研究的目的:
- 为了比较两个胚胎移植策略之间的生育结果.
- 调查新鲜的双裂变阶段胚胎移植 (DET) 与新鲜的单裂变阶段胚胎移植 (SET) 以及冷的胚芽细胞阶段SET的疗效.
主要方法:
- 追溯匹配的队列研究.
- 新鲜SET+冷芽细胞SET (2xSET) 的976个周期和新鲜DET.的976个周期的数据.
- 根据年龄 (<38 vs. ≥38岁) 和胚胎可用性的子组分析.
主要成果:
- 与新鲜的DET相比,2xSET策略显著增加了临床怀孕 (55.5%与42%相比) 和活产 (44.8%与34.5%相比)
- 在2xSET组中,早产率较低 (调整后OR为0.64).
- 在38岁以上或只有两个可使用胚胎的妇女中没有观察到2xSET的好处.
结论:
- 对于38岁以下有2个胚胎的女性,建议采用新鲜SET的策略,然后采用冷芽细胞SET.
- 这种方法提高了活产率,并减少了与新鲜DET相比的多胎出生.
- 这种策略可以减轻胚胎细胞培养失败的风险,同时保持高的成功率.

In Vitro Fertilization
223
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
182.9K
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...
