概括
精液静态氧化降低潜力 (sORP) 与不育男性的精子参数或氧化应激生物标志物不一致相关. 这些发现表明,sORP可能不是评估男性不孕症的可靠指标.
科学领域:
- 生殖医学 生殖医学
- 安德罗学与人类学
- 生物标志物研究 生物标志物研究
背景情况:
- 男性不孕症影响全球众多夫妇,氧化应激被确定为关键因素.
- 异形性男性因子不孕症和不明原因不孕症病例占男性生殖挑战的很大一部分.
研究的目的:
- 调查精液静态氧化降低潜力 (SORP) 和精子质量参数之间的相关性.
- 评估sORP和已确定的氧化应激生物标志物在不孕男性之间的关系.
主要方法:
- 一项横截面研究包括202名患有异常男性因子不孕症或不明原因不孕症的男性.
- 采用多变量线性回归分析来检查sORP,精子参数和脂质过氧化和DNA碎片化等生物标志物之间的关联.
主要成果:
- 在sORP和标准精液分析参数之间没有发现线性关联.
- sORP与脂质过氧化有反向关系,但与精子DNA碎片化有积极关联.
- sORP与线粒体膜潜力或附件V之间的关系并不显著.
结论:

Spermatogenesis
102.2K
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...

Infertility in Males
253
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
