概括
维生素D补充剂在经过冷胚胎移植 (FET) 周期的妇女中没有改善怀孕率. 这项研究发现,服用维生素D补充剂的维生素D缺乏妇女和服用维生素D补充剂的妇女之间持续怀孕率没有显著差异. 需要进一步的研究.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 不孕症研究 不孕症研究
- 维生素D的新陈代谢
背景情况:
- 血清25-OH D3 (D3) 在女性生殖生理学中起作用.
- 以前的研究表明,足够的D3水平与改善体外受精 (IVF) 结果之间存在联系,但研究结果相矛盾.
- 在试管婴儿前补充D3不足是常见的,但其对冷胚胎移植 (FET) 周期和临床结果的影响尚不清楚.
研究的目的:
- 调查维生素D补充剂对接受FET周期的女性的影响.
- 评估维生素D状态对FET期间临床结果的影响.
- 为了确定纠正D3不足是否改善FET周期中的怀孕率.
主要方法:
- 对252名接受FET周期的不育妇女进行前性研究.
- 初始查血清25-OH D3 (D3) 水平;115人 (45.6%) 的D3不足 (<30 ng/mL),并接受标准化补充剂.
- 在三个时间点测量血清D3水平:子宫内膜制备启动 (T1),胚胎移植 (T2) 和β-hCG测试 (T3).
主要成果:
- 接受维生素D3不足的参与者和接受维生素D3补充的参与者之间持续怀孕率没有显著差异 (34.8%与37.2%,或0.90).
- 对于活产,阳性β-hCG,临床怀孕,流产和宫外妊娠率的类似非显著发现.
- 在D3不足和充满组之间在T2和T3没有观察到持续怀孕率或其他结果的显著差异.
结论:
- 在子宫内膜制备开始时开始的维生素D补充剂在接受FET周期的妇女中没有显著改善正在进行的怀孕率.
- 该研究发现,在接受补充剂的D3缺乏妇女和接受D3补充的妇女之间,FET结果没有显著差异.
- 需要进行更大规模,高质量的试验,以最终评估维生素D状态和补充剂对IVF/FET结果的影响.

In Vitro Fertilization
150
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...

Meiosis II
181.5K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...
