概括
无法解释的不孕不育 (UI) 可能涉及毛囊液 (FF) 代谢的改变. 这项研究在UI的女性中发现了特定的代谢物变化,包括较低的维生素D衍生物,这表明了潜在的诊断标记.
科学领域:
- 生殖医学和内分泌学.
- 代谢学和分子诊断学
背景情况:
- 无法解释的不孕不育 (UI) 影响约10%的不孕不育夫妇,标准诊断往往无法确定原因.
- 毛囊液 (FF) 在卵细胞发育中起着至关重要的作用,可能含有潜在分子干扰的代谢物.
- 研究FF代谢组为了解UI的病理生理学提供了一种新的方法.
研究的目的:
- 与对照人群相比,探索和确定患有不明原因不孕症 (UI) 的女性毛囊液中的代谢变化.
- 通过全面的代谢概况,调查与UI相关的潜在代谢生物标志物.
主要方法:
- 从20名接受试管婴儿的女性 (10名UI,10名男性因子不育) 收集了毛囊液 (FF).
- 用液体染色学与Q-TOF-MS/MS.相结合进行了新陈代谢分析.
- 数据分析涉及XCMS在线,MetaboAnalyst,OPLS-DA和KEGG途径分析,用于代谢物识别和途径映射.
主要成果:
- 在UI的女性中,差异代谢物分析确定了12个显著降低的代谢物 (例如,二甲,酸,维生素D3衍生物) 和一个增加的代谢物 (Ile-Lys-Val-Val).
- 途径分析显示了甘油脂,甘油脂,类固醇和酸代谢的干扰.
- 针对性分析证实,UI的女性的卵泡25-基维生素D[25(OH) D]水平显著降低,尽管补充了.
结论:
- 患有不明原因不孕症 (UI) 的女性的毛囊液代谢表现出明显的变化,特别是在脂质和维生素D代谢中.
- 减少的卵泡25-基维生素D [25(OH) D]水平表明,在UI的妇女的卵泡微环境中,维生素D的可用性受到调节.
- 这些发现提供了对未解释不育 (UI) 的潜在代谢生物标志物的初步见解.

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.

Oogenesis
70.8K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
