背景情况:
- 菌毒素是真菌产生的有毒二次代谢物,可以污染食物并对人类健康构成风险.
- 男性不孕症是一个日益严重的问题,环境因素,如真菌毒素暴露越来越多地被调查为潜在的贡献者.
- 了解真菌毒素对精液质量的特定影响对于受影响地区的公共卫生倡议至关重要.
研究的目的:
- 调查尼日利亚男性暴露于特定的真菌毒素 (zearalenone, ochratoxin A,deoxyvinelol) 和精液质量参数之间的关联.
- 为了比较患有精子质量下降的男性和健康对照者的尿液中mycotoxin代谢物水平.
- 为了确定菌毒素暴露是否会影响精子数量,运动性或形态.
主要方法:

Infertility in Males
261
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...

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...
