概括
丸的炎症,或炎,通过损害精子生产导致不孕. 未成熟的塞尔托利细胞和FSH水平升高是男性严重丸损伤的关键指标.
科学领域:
- 生殖免疫学 生殖免疫学
- 安德罗学与人类学
- 病理学 病理学 病理学
背景情况:
- 实验性自身免疫性耳炎 (EAO) 是用于研究丸自身免疫和不孕症的动物模型.
- 在患有炎症的不孕症患者中对人类丸活检的分析是有限的.
- 了解免疫细胞在丸功能障碍中的作用对于不孕症研究至关重要.
研究的目的:
- 为了比较免疫细胞的存在,塞尔托利细胞 (SC) 的改变,以及人类丸活检中的荷尔蒙水平与EAO.
- 为了研究炎症,SC表型和精子生成之间的关系,在低精子生成 (HypoSp) 和塞尔托利单细胞综合征 (SCOS) 中.
- 为了识别人类炎中严重丸损伤的标志物.
主要方法:
- 分析了患有轻度/重度HypoSp,阻塞性亚精 (对照) 和SCOS的患者的丸活检.
- 评估了免疫细胞 (CD45+),细胞亡的生殖细胞,精子,塞尔托利细胞 (SCs) 和激素水平 (FSH).
- 将人类数据与EAO的老鼠的发现进行了比较.
主要成果:
- 严重的HypoSp显示CD45+细胞增加,生殖细胞亡,精子生殖减少.
- SCOS和严重的HypoSp表现出不成熟的SCs (高AMH),与高FSH和CD45+细胞相关.
- EAO模型显示免疫细胞增加,生殖细胞亡,精子缩,成熟的SCs (低AMH),但损坏的管道数量增加.
结论:
- 慢性炎症,FSH升高,免疫细胞透和不成熟的SC表型与人类严重的精子生成障碍和亚精子症有关.
- 在SC中AMH和Ki67表达是人类炎中严重丸变化的特征标记.
- 耳炎显著降低了精子数量,生存能力和运动能力.

Spermatogenesis
102.4K
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
260
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...
