- 动物科学动物科学
- 生物化学 生化学
背景情况:
- 神经生长因子 (NGF) 在雄性驼类动物的黄素激素 (LH) 释放中起作用.
- 精液NGF与丸激素水平的增加有关,这表明它可能在男性生育能力中发挥作用.
研究的目的:
- 为了研究种子NGF度和雄性繁殖特征之间的关联.
- 为了确定精液NGF是否预测雄性阿尔帕卡的繁殖表现和生育能力.
主要方法:

01:41Spermatogenesis
102.5K
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...

01:23Infertility in Males
267
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...
