概括
总胚胎细胞可用率 (TBUR) 在IVF中显著影响累积活产率 (CLBR). 更高的TBUR与更好的CLBR结果有关,为生育治疗提供了有价值的预后工具.
科学领域:
- 生殖医学 生殖医学
- 在体外受精 (IVF)
- 胚胎学 胚胎学
背景情况:
- 在试管婴儿中,优化累积活产率 (CLBR) 是至关重要的.
- 胚胎细胞发育指标,特别是胚胎细胞总可用率 (TBUR),正作为关键绩效指标受到越来越多的关注.
- 了解CLBR的预后因素对于改善试管婴儿成功至关重要.
研究的目的:
- 为了确定总胚胎囊可用率 (TBUR) 是否与累积活产率 (CLBR) 有意义地相关.
- 评估TBUR作为试管婴儿结果的预后因素.
主要方法:
- 对317个IVF/ICSI周期 (2014-2020年) 进行了一项单心回顾性研究.
- 总胚胎囊可用率 (TBUR) 被计算为每2PN的可用胚胎囊.
- 在2年的随访期内评估了CLBR,比较了TBUR≥50%的周期和TBUR≤30%的周期.
主要成果:
- 累积活产率 (CLBR) 在高TBUR组 (≥50%) 与低TBUR组 (≤30%) 相比显著更高 (57%对41%,p=0.02).
- 经调整后勤回归证实了CLBR和TBUR (OR=0.408,p=0.04) 之间的显著关联.
- 较低的TBUR (≤30%) 与实现活产的机会显著降低有关.
结论:
- 总胚胎细胞可用率 (TBUR) 是试管婴儿周期中CLBR的一个有价值的预后因素.

In Vitro Fertilization
247
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...

Cleavage and Blastulation
45.1K
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.
