当只有一个囊可供转移时,囊与卵巢的比率是否预测活产?
Gynecologic and obstetric investigation
|August 28, 2025
概括
只有一个胚胎被移植时,胚胎对卵细胞的比率不会影响活产率 (LBR). 女人的年龄和胚胎质量是实现活产的关键因素.
科学领域:
- 生殖医学
- 胚胎学
- 在体外受精 (IVF)
背景情况:
- 在试管婴儿中,卵细胞检索数量和随后的胚胎细胞发育是至关重要的.
- 胚胎细胞与卵细胞的比率通常被认为是卵巢反应和胚胎质量的指标.
- 了解影响活产率 (LBR) 的因素对于优化试管婴儿结果至关重要.
研究的目的:
- 评估胚胎细胞与卵细胞的比率是否影响单个胚胎细胞转移周期的活产率 (LBR).
- 在单胞胎冷胚胎转移 (FET) 周期中确定LBR的主要预测因素.
主要方法:
- 一个回顾性队列研究,对2,125个单个胚胎细胞冷移植 (FET) 周期进行了研究.
- 患者根据胚胎细胞与卵细胞的比例分层.
- 使用后勤回归分析来确定LBR的预测因素,包括女性年龄,胚胎质量和BMI.
主要成果:
- 胚胎细胞与卵细胞的比率没有与LBR显著相关.
- 女性年龄和胚胎质量被确定为LBR的独立预测因素.
- 在胚胎细胞与卵细胞比率最低的四分位数中观察到年龄较小和AMH水平较高.
结论:
- 在单个胚胎细胞转移周期中,胚胎细胞与卵细胞的比率不是LBR的重要决定因素.
- 女性的年龄和胚胎质量是影响活产成功的最关键因素.
- 胚胎选择至关重要,而不是仅仅依靠卵巢反应指标,以优化试管婴儿的结果.

01:33Cleavage and Blastulation
45.7K
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.

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...
