概括

在hCG触发日的薄子宫内膜厚度 (EMT) 为7.8毫米或更小,与新鲜胚胎移植 (ET) 后单独生儿早产的可能性更高有关. 这一发现凸显了EMT在预测新生儿后果方面的重要性.

科学领域:

生殖医学生殖医学
新生儿结局的结果.
在体外受精 (IVF)

背景情况:

生产率可能与新鲜胚胎移植 (ET) 后的子宫内膜厚度 (EMT) 相相关.
在新生试管婴儿周期中,EMT与新生儿结局之间的关联仍然不清楚.

研究的目的:

研究hCG触发日内子宫内膜厚度 (EMT) 与新生儿结局在新生胚胎移植 (ET) 后出生的单胎婴儿之间的关系.

主要方法:

对2010年接受自主试管婴儿周期的女性进行了回顾性研究.
多变量回归分析和平滑曲线适配,以评估EMT对新生儿结果的影响.
值效应分析以确定EMT的准确切割值.

主要成果:

随着EMT的增加,观察到早产 (PTD) 的几率降低 (例如,9.00-9.90毫米:45%的减少;>11毫米:75%的减少).
增加EMT与减少PTD和增加妊娠年龄 (GA) 相关联.
一个EMT≤7.8毫米被确定为增加PTD几率和减少GA的预测因素.

结论:

在hCG触发日的子宫内膜薄 (≤7.8毫米) 与新鲜的ET后单身婴儿早产的几率增加有关.
虽然增加的EMT显示出更好的结果的趋势,但适度的GA差异的临床相关性需要进一步调查.
该研究的回顾性设计是一个局限性;进一步的前性研究是合理的.

关键词:

Histology of the Uterus

Histology of the Uterus

The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.
The endometrium is the...

Proliferative Phase

Proliferative Phase

The proliferative phase typically occurs after menstruation and lasts between 6 to 13 days in a standard 28-day cycle. This phase involves the reconstruction of the endometrium, guided by estrogen produced by the developing ovarian follicle.
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
