概括

与其他方法相比,精子分离装置 (SSD) 有效地选择具有高运动性的精子,与DNA损伤相比较少. 需要进一步的研究来确认SSD是否改善了IVF中的胚胎结果.

科学领域:

生殖医学生殖医学
精子生物学精子生物学
辅助生殖技术辅助生殖技术

背景情况:

精子制备对于医疗辅助生殖 (MAR) 是至关重要的.
优化精子选择可以提高受精率和怀孕率.
识别优秀的精子制备技术是一个正在进行的研究领域.

研究的目的:

为了比较四种精子制备方法来选择最佳的精子种群MAR.
评估不同精子选择程序对精液参数的影响.

主要方法:

一项前性观察研究分析了四种精子制备方法:密度梯度离心 (DGC),精子冲洗 (SW),用磁激活细胞分类 (MACS) 进行DGC和精子分离装置 (SSD).
精液分片被评估为渐进的运动性,形态学,宏体指数 (AI) 和DNA碎片化指数 (DFI).

主要成果:

精子分离装置 (SSD) 在渐进运动性和DNA碎片化指数 (DFI) 中与DGC显示出强烈的分歧.
与DGC相比,MACS和SSD都显著减少了DFI.
与MACS相比,SSD导致细胞缩和死亡精子的百分比显著降低.

结论:

精子分离装置 (SSD) 非常适合选择具有减少DNA损伤的运动精子.
在试管婴儿中SSD对胚胎学结果的临床益处需要进一步调查.

关键词:

在DGC上,你会看到DGC.在 FERTILE plus® 公司,我们提供:美国国务院调查局 (ICSI)马克斯 (MACS) 是一个指标.精子精子精子精子分离装置是一种精子分离装置.

Spermatogenesis

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...
