概括
一个结一切的策略改善了IVF中的活产率. 对于分裂阶段的转移,如果雌激素峰值超过3900 pg/mL,则冷胚胎转移优越,对于胚胎细胞转移,如果雌激素峰值超过2000 pg/mL,则更优越.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 在体外受精 (IVF)
背景情况:
- 卵巢刺激会导致雌激醇水平升高,这可能会影响子宫内膜受体和妊娠结果.
- 影响新鲜或冷胚胎转移成功的雌激素峰值的最佳值,因胚胎阶段而异,尚未确定.
研究的目的:
- 确定雌激素水平的峰值值,以区分新鲜和冷胚胎转移之间的妊娠结果.
- 为了调查这个值是否会根据被移植的胚胎分裂阶段或胚囊胚胎转移而变化.
主要方法:
- 来自四项多中心随机试验的数据的二次分析,涉及6153名患者.
- 新鲜和冷胚胎移植策略之间的活产率的比较.
- 血清雌激素水平的峰值是在人类胆性腺激素 (hCG) 给药的那一天测量.
主要成果:
- 在胚胎移植阶段和战略 (新鲜与冷) 之间观察到对活产率 (p=0.016) 的相互作用.
- 对于切割阶段转移,冷胚胎转移显示,当雌激素峰值>3900 pg/mL (55.4%对44.9%) 时,活产率更高.
- 对于胚芽细胞移植,冷胚胎移植在雌激素峰值>2000 pg/mL (54.3%对比37.7%) 时,产生了更高的活产率.
结论:
- 一个结一切的策略可能会提高IVF的活产率.
- 特定的峰值雌激素值 (切割时>3900 pg/mL,囊胞时>2000 pg/mL) 表明结全方位方法何时更有利.

Cleavage and Blastulation
49.7K
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

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...
