概括
在辅助生殖技术中转移完全化 (FH) 和未完全化 (NFH) 胚芽细胞产生类似的活产率和围产期结果. 这一发现适用于前植入前遗传测试 (PGT-A) 和非PGT周期,为生育治疗提供了可比的结果.
科学领域:
- 生殖科学 生殖科学
- 胚胎学 胚胎学
- 围产儿医学 围产儿医学
背景情况:
- 胚胎细胞化是胚胎发育的关键阶段.
- 胚胎囊化程度 (完全化与未完全化) 可能会影响植入和怀孕的结果.
- 辅助生殖技术 (ART) 涉及精心选择用于移植的胚胎.
研究的目的:
- 为了在ART中比较完全化 (FH) 和未完全化 (NFH) 芽细胞移植之间的临床和周产期结局.
- 评估胚胎囊化状态对活产率和围产期健康的影响.
- 为了评估前植入前遗传测试的结果,以检测形积分 (PGT-A) 和非PGT周期.
主要方法:
- 对女性进行回顾性分析,她们进行了第一次卵细胞检索周期,并采用了结所有策略.
- 循环分类为PGT-A,解芽细胞 (解芽细胞) 和从解第3天胚胎培养的芽细胞 (解芽细胞-d3).
- 怀孕和围产期结果的比较,以活产率作为主要结果;使用回归模型和倾向得分匹配的统计调整.
主要成果:
- 在PGT-A周期中,FH和NFH芽细胞体之间的植入率,流产率或活产率没有显著差异.
- 在PGT-A周期中,在FH和NFH芽细胞移植之间观察到可比的围产期结局.
- 在解-爆发和爆发-解-d3周期中发现了类似的怀孕和围产期结局,而不管胚胎细胞化状态如何.
结论:
- 胚胎囊的化状态 (完全化或未完全化) 不会显著影响ART的怀孕或围产期结果.
- 这些发现在PGT-A和非PGT周期中一致.
- 仅基于化程度的胚胎选择可能不是成功的ART结果的关键决定因素.

Cleavage and Blastulation
46.0K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Teratogenicity
2.8K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
