概括
无线设备对电磁场 (EMF) 的暴露显著降低了精子的运动性,并在健康男性中增加了亡症状. 需要进一步的研究来了解电磁场对男性生育能力的长期影响.
科学领域:
- 生殖生物学 生殖生物学
- 环境健康 环境健康
- 细胞生物学 细胞生物学
背景情况:
- 不孕症影响人口的很大一部分,男性因素导致近一半的病例.
- 电磁场 (EMF) 发射技术的广泛使用需要了解其潜在的生物效应.
- 之前的研究已经使用体外和体内模型探索了电磁场的影响,但对人类精子的直接影响需要进一步调查.
研究的目的:
- 调查900 MHz电磁场辐射对人类精子参数的直接体外影响.
- 评估EMF暴露对精子遗传状况,亡标记物和PI3K/AKT信号通路的影响.
- 为了评估这些效应在健康的normozoospermic男性.
主要方法:
- 来自健康男性的精液样本分为对照组和暴露于EMF的组 (30分钟和1小时).
- 分析了精子参数,包括运动性,形态和体索引.
- 评估了遗传状态 (DNA碎片化,染色质完整性),细胞亡标记物 (cytokine-c,caspase-3) 和PI3K/AKT通路组件.
主要成果:
- 经过30分钟的电磁场暴露后,观察到精子运动率显著降低.
- 在1小时EMF暴露组中,发现化AKT (p-AKT) 的表达增加.
- 两个EMF暴露组都显示出增加的真空化,体缺陷,破坏的染色质,亡症状和受损的轴膜,这些缺陷在对照组中没有.
结论:
- 在体外暴露于900 MHz EMF会对精子运动产生负面影响,并诱导人类精子中显著的结构和亡损伤.
- 虽然p-AKT表达增加,但其他评估的参数,如形态,遗传完整性和PI3K表达没有显著变化.
- 这些发现突显了EMF暴露对男性生殖健康的潜在风险,并要求进一步调查潜在机制和长期后果.

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
250
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...
