概括
在体外受精 (IVF) 之前的例行子宫镜检查并没有改善正常子宫腔超声波的不孕妇女的活产率. 因此,对于这些接受第一次试管婴儿周期的患者,不建议进行例行透镜检查.
科学领域:
- 生殖医学
- 妇科手术
- 临床试验
背景情况:
- 在接受体外受精 (IVF) 的不孕妇女中,为了提高怀孕成功率,经常进行宫镜检查.
- 然而,随机对照试验 (RCT) 缺乏支持这种做法的强有力的证据.
- 这项研究旨在评估第一轮试管婴儿周期前常规宫内镜检查对活产率的有效性.
研究的目的:
- 要确定在第一次体外受精 (IVF) 治疗周期之前的例行子宫镜是否会增加活产率.
- 提供基于证据的建议,用于在试管婴儿前经过阴道超声检查发现正常的不孕女性的治疗.
主要方法:
- 一项实用的多中心随机对照试验涉及750名计划接受首次试管婴儿治疗的妇女.
- 经过正常的阴道超声波和没有先前的宫内镜检查的参与者被随机分配 (1:1) 接受潜在治疗的宫内镜检查或立即试管婴儿.
- 主要结局是持续的怀孕导致18个月内活产,根据治疗意向进行分析.
主要成果:
- 在透镜组 (57%) 和直接试管婴儿组 (54%) 之间没有发现活产率的显著差异 (相对风险为1. 06,95% CI为0. 93-1. 20;p=0. 41).
- 透视后子宫内膜炎的发病率在透视组中低于1%.
- 该试验在2011年5月至2013年8月期间招募了750名女性.
结论:
- 在计划进行第一次试管婴儿治疗的女性中,常规的宫内镜检查并不能改善活产率.
- 这些发现表明,不应为这种患者群体提供常规透镜.
- 这项研究提供了指导辅助生殖技术临床实践的关键证据.

In Vitro Fertilization
1.3K
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...

Infertility in Females
5.0K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
