概括
每天服用400毫克口服微型化孕激素的持续怀孕率与试管婴儿中黄体阶段支持的阴道孕激素凝相比,表现不逊色. 这为患者提供了潜在的更可接受的替代方案.
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.
- 在妇科的临床试验.
背景情况:
- 在新鲜的试管婴儿周期中,质阶段支持 (LPS) 是至关重要的,但最佳方案仍在争论中.
- 阴道孕激素虽然很常见,但由于成本和注射途径而面临接受问题.
- 由于潜在的低生物可用性,口服微化孕激素的有效性受到质疑.
研究的目的:
- 为了确定口服微化孕激素 (OMP) 是否与阴道孕激素凝相比,在新鲜胚胎移植周期中持续怀孕率方面不逊色.
- 为了比较不同剂量的OMP与阴道孕激素凝的疗效.
主要方法:
- 一个非劣势随机试验,涉及1310名经历第一或第二次试管婴儿周期的不孕妇女.
- 参与者接受LPS的OMP (400毫克/天或600毫克/天) 或阴道孕激素凝 (90毫克/天).
- 主要结局是持续怀孕率,评估到11-12周的妊娠期.
主要成果:
- 400毫克OMP的持续怀孕率与阴道孕凝 (35.3%对38.0%) 不逊色.
- 与阴道孕激素凝 (31.6%与38.0%) 相比,对600毫克OMP组的非劣质性没有确立.
- 两组之间没有观察到活产率的统计学上显著差异.
结论:
- 口服微化孕激素400毫克/天可以作为LPS的阴道孕激素凝的可行替代品.
- 需要进一步的研究来确认活产率,并调查更高剂量的OMP的潜在影响.
- 这些发现可能不直接适用于使用性腺激素释放激素激素激素触发卵细胞成熟的试管婴儿周期.

Ovarian Cycle
1.3K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

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...
