概括
与马匹的精液相比,与驴子精液进行的非物种繁殖并没有增加马匹精液的繁殖后炎症. 驴子精液血显示出抗炎性质,可能是由于前列腺素度较高.
科学领域:
- 生殖免疫学 生殖免疫学
- 马类繁殖的繁殖方式
- 比較免疫學 比較免疫學
背景情况:
- 在马匹中进行的非物种繁殖有时比物种内繁殖更成功.
- 驴子精液和精液等离子体对大马子宫内膜的免疫调节作用尚不清楚.
- 事证据表明,与驴一起繁殖的马匹的生育能力得到改善,炎症减少.
研究的目的:
- 为了比较暴露在驴子和马精液和精液等离子体中的马的繁殖后炎症反应.
- 评估驴子和马的精子和精液等离子体的蛋白质和代谢特征.
- 评估对子宫,液体积累,中性粒细胞透和细胞因子概况的影响.
主要方法:
- 在精液/精液等离子体输注前和后测量了大母子宫炎症标志物 (,液体,中性粒细胞,细胞因子).
- 分析了孕激素和炎症性细胞因子 (IL1A,IL1B,IL4,IL6,CXCL8,IL10) 的度.
- 使用LC-MS/MS进行了精液和精液等离子体的蛋白质和代谢分析.
主要成果:
- 驴子精液输液倾向于在输液后6小时导致较低的炎症反应 (P = 0.074).
- 在子宫细胞学中,驴精液血显著减少了中性粒细胞的透 (P < 0.05),表明具有抗炎性质.
- 马的精液增加了IL6和降低了IL1B度,而驴的精液/血显示了PGE1,PGE3和乳酸的度更高.
结论:
- 使用驴精液的繁殖母马引发了与马精液相似的繁殖后子宫内膜炎.
- 驴子精液血具有抗炎性质,与其他组合相比,导致炎症反应减少.
- 驴子精液/血中丰富的前列腺素可能有助于在物种间繁殖中产生免疫调节作用.

Fertilization
70.9K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Sperm Transport
794
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
The maturation phase occurs in the epididymis, where sperm...

Sperm Structure and Semen Composition
2.0K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

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...
