概括
高精子DNA碎片化 (SDF) 对辅助生殖技术 (ART) 的成功率产生负面影响,特别是在试管婴儿和IUI. 虽然其对ICSI的影响较弱,但SDF升高与ICSI周期中妊娠损失增加有关.
科学领域:
- 生殖医学 生殖医学
- 男人不孕症研究研究
- 辅助生殖技术 (ART) 是一种辅助生殖技术.
背景情况:
- 男性不孕症对全球不孕症问题做出了重大贡献.
- 传统的精液分析对精子功能的洞察力有限.
- 精子DNA碎片化 (SDF) 是精子核质量的潜在指标,但其在ART中的临床实用性仍有争议.
研究的目的:
- 执行现有元分析的总体元分析.
- 评估SDF和关键ART结果之间的关联:临床妊娠 (CP),妊娠流产 (PL) 和活产率 (LBR).
主要方法:
- 在主要数据库 (PubMed,Embase,Web of Science,Scopus,Cochrane Library) 进行系统的文献搜索,截至2025年7月.
- 包括系统性审查与SDF在IVF,ICSI和IUI中的元分析.
- 使用AMSTAR-2和GRADE框架评估证据质量.
主要成果:
- 分析了8个覆盖超过25,000个ART周期的元分析.
- 增加的SDF与IVF和IUI中的CP降低相关,以及ICSI中的边界关联.
- 在ICSI周期中,高的SDF与增加的PL有很强的关联.
- 关于LBR的证据有限且不确.
- 由于异质性和方法上的局限性,总体证据确定性很低.
结论:
- 增加的SDF会对ART的结果产生不利影响,特别是在试管婴儿和IUI中.
- 在ICSI结果中发现了一个微弱的关联,但在ICSI中观察到与流产的强烈联系.
- 结果强调了SDF的预后价值,但强调了对标准化测试和进一步的临床整合前性研究的需要.

Fertilization
89.6K
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...

Meiosis I
43.8K
Meiosis is the division of a diploid cell into haploid cells forming sperm and eggs in animals through differentiation. Meiosis I is the first stage of meiosis, where the genetic recombination of homologous chromosomes and the reduction of the ploidy level by half occurs.
Prophase I is the most extended and complex step of meiosis I characterized by synapsis, chromosome pairing, and recombination of the homologous chromosomes. This process is facilitated by a proteinaceous structure called the...
