概括

辅助生殖技术 (ART) 孕育的三倍胎盘比体内孕育的胎盘有更多的异常. 这些胎盘问题可能解释了ART怀孕三胞胎中更高的不良妊娠结果.

科学领域:

生殖医学生殖医学
周围生理学周围生理学
病理学病理学病理学

背景情况:

辅助生殖技术 (ART) 越来越多地用于多胎妊娠.
三胞胎怀孕带来了独特的胎盘挑战.
ART对三胞胎胎的胎盘形态和病理的影响需要研究.

研究的目的:

通过ART怀孕和体内怀孕的三胎妊娠之间的胎盘异常进行比较.
在三胎妊娠中识别与ART相关的特定胎盘病理.

主要方法:

98例三胎妊娠的回顾性病例控制研究,包括胎盘检查.
在ART (体外受精,细胞内精子注射) 和体内受精 (自然受精,人工授精) 三胞胎之间的比较.
对胎盘特征和妊娠结果的单变量和多变量分析.

主要成果:

在ART三胞胎中,二三胞胎胎胎位,胎儿生长限制,新生儿死亡和NICU入院率较高.
ART胎盘的重量较小,边缘和状绳索插入的频率更高.
组织学检查显示慢性小炎增加,小成熟加速,纤维素沉积和ART胎盘中的胆血管瘤.

结论:

与体内受孕的三胞胎相比,人工智能孕育三胞胎的胎盘异常负担更高.
这些胎盘发现可能有助于在ART怀孕的三胞胎中观察到的不良妊娠结果.
对免疫和血管因素的进一步研究是有必要的,以改善管理.

关键词:

辅助生殖技术是一种辅助生殖技术.多重怀孕是一个多重的怀孕.胎盘评价胎盘评价三胞胎的胎盘和胎盘.三胞胎怀孕是指三胞胎的怀孕.

Teratogenicity

Teratogenicity

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...
