概括
45岁以上妇女的卵子捐赠怀孕与年轻的接受者相比,没有产科或产周并发症的风险增加. 这与自发怀孕形成鲜明对比,在这种情况下,母亲的晚年与更高的风险有关.
科学领域:
- 生殖医学 生殖医学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 产科 产科 产科 产科 产科
背景情况:
- 关于45岁以上的卵细胞捐赠 (OD) 接受者的怀孕和围产期结局的数据有限.
- 晚期母亲年龄通常与自发怀孕中产科和周产期风险的增加有关.
研究的目的:
- 为了比较较年龄较大 (≥45岁) 和年轻 (<45岁) 卵细胞捐赠受体之间的怀孕和周产期结果.
- 将这些结果与类似年龄组的自发怀孕妇女的结果进行比较.
主要方法:
- 追溯分析了459528例单独怀孕,包括946例OD怀孕和458582例自发怀孕.
- 怀孕被按孕妇年龄 (≥45岁与<45岁) 和受孕方法 (OD与自发) 分类.
- 使用多变量逻辑回归来评估早产 (PTB) 和妊娠年龄 (SGA) 的小风险.
主要成果:
- 与年轻的OD接受者相比,45岁以上的卵子捐赠接受者没有增加产科或产周病率.
- 相比之下,自发怀孕的45岁以上女性面临着明显更高的PTB (<37周和<34周),SGA和妊娠引起的高血压风险.
- 产科并发症在OD接受者的年龄组之间是可比的,但在自发怀孕的老年女性中更高.
结论:
- 45岁以上接受者的卵子捐赠怀孕与较年轻的OD接受者相比没有增加产科或围产期发病率.
- 接受卵子捐赠的母亲的晚年并没有与自发怀孕的风险相同.
- 卵子捐赠可以减轻与怀孕中母亲晚年相关的一些风险.

Oogenesis
63.3K
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...

Nondisjunction
3.7K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Meiosis vs. Mitosis
52.3K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
