概括
30%以上的高精子DNA碎片化 (SDF) 与辅助生殖技术 (ART) 周期中较少的幼胚胎有关. 这表明精子DNA完整性对胚胎染色体正常性的值效应.
科学领域:
- 生殖医学 生殖医学
- 遗传学 是一个遗传学.
- 不孕症研究 不孕症研究
背景情况:
- 精子DNA碎片化 (SDF) 是男性不孕不育的潜在指标.
- 它与辅助生殖技术 (ART) 中胚胎繁殖的关联需要进一步澄清.
研究的目的:
- 在ART周期中量化评估SDF和胚胎euploidy率之间的联系.
- 评估SDF水平是否会影响获得染色体正常胚胎的可能性.
主要方法:
- 按照PRISMA 2020指南进行系统审查和元分析.
- 搜索了主要的数据库 (PubMed,科学网,Embase,Scopus,Cochrane) 至2025年8月.
- 包括对IVF/ICSI周期的研究,其中测量了SDF和PGT-A对euploidy.
主要成果:
- 分析了6项研究 (1,516个周期),所有这些研究都使用精子染色素结构测定 (SCSA).
- 在15%的切割值下,高SDF和胚胎euploidy之间没有发现显著的关联.
- SDF ≥30%与较低的胚胎化率 (OR=0.742,95% CI 0.558-0.988) 有意义地相关.
结论:
- 高SDF (>30%) 与获得euploid胚胎的机会降低有关.
- 研究结果表明,精子DNA完整性对胚胎染色体正常性的影响取决于值.

Nondisjunction
4.8K
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...

Fertilization
89.4K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
