概括
在辅助生殖中,激素释放激素激素激素剂 (GnRHa) 方案在长期和短期方案之间活产率几乎没有差异. 长时间的方案可能会提高临床怀孕率,但关于OHSS和流产的证据是不确定的.
科学领域:
- 生殖内分泌学和不孕不育问题
- 辅助生殖技术 (ART) 是一种辅助生殖技术.
- 临床试验分析
背景情况:
- 淋巴激素释放激素激动剂 (GnRHa) 在辅助生殖技术 (ART) 中至关重要,以防止在受控卵巢过度刺激 (COH) 期间过早的黄素化激素 (LH) 激增.
- 优化GnRHa协议旨在提高生育治疗中的活产率.
- 这项研究系统地审查和比较了在ART中使用的各种GnRHa协议的疗效和安全性.
研究的目的:
- 评估不同GnRHa协议的有效性和安全性,作为控制卵巢过度刺激 (COH) 的附加剂,在接受辅助生殖技术 (ART) 的女性中.
- 为了比较在生育治疗中使用的各种GnRHa协议的益处和风险.
主要方法:
- 进行了随机对照试验 (RCT) 的系统审查和元分析,搜索主要数据库到2022年12月.
- 包括40个RCT (4148名女性),比较不同的GnRHa协议,剂量或IVF/ICSI周期的持续时间.
- 主要结局包括活产/正在进行的怀孕率和卵巢过度刺激综合征 (OHSS) 发生率;次要结局包括临床怀孕,卵细胞产量,淋巴激素使用和成本.
主要成果:
- 在比较长期和短期GnRHa协议时,在活产或持续怀孕率 (低确定性证据) 中几乎没有差异.
- 较短的协议 (低确定性证据) 与较长的协议相比,长期协议可能会提高临床怀孕率.
- 由于数据有限,关于OHSS,流产率和其他不良事件的证据是不确定的;成本效益和可接受性没有报告.
结论:
- 虽然长时间的GnRHa协议在临床怀孕率上可能会带来轻微的优势,但与短时间的协议相比,它们在活产率上几乎没有差异.
- 由于现有试验报告不足,不同GnRHa协议的比较安全性 (OHSS,流产) 概况存在重大不确定性.
- 需要进一步进行高质量的研究,特别关注活产生的结果,不良事件和患者报告的措施,如成本和可接受性.

In Vitro Fertilization
213
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...

Hormones of the Pituitary Gland
6.3K
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...
