The biochemical composition of seminal plasma (SP) is very complex and variable among species. Advances in reproductive technologies reveal SP as a nutritive-protective medium for sperm cells suspended in it, and some SP components are very important for sperm metabolism, as well as sperm function, survival, and transport in the female reproductive tract. Biochemistry of SP is a relatively modern but rapidly expanding field of research, particularly concerning the biological significance of the various biochemical constituents of SP. However, identification of active factors in SP and mechanisms by which they act are not sufficiently understood in different species. Especially in camelids, the origin, composition, and function of the viscous component of SP remain a mystery, and only some biochemical and morphological characteristics of SP have been described. In this review, we focus on the current understanding of physiological and biochemical properties of SP in ruminants and camelids.
精浆（SP）的生化组成非常复杂，且因物种而异。生殖技术的进步表明，精浆是悬浮其中的精子细胞的营养保护介质，一些精浆成分对精子代谢以及精子在女性生殖道中的功能、存活和运输非常重要。精浆生物化学是一个相对现代但迅速发展的研究领域，特别是关于精浆各种生化成分的生物学意义。然而，不同物种对精浆中活性因子及其作用机制的认识还不够充分。特别是在骆驼科动物中，精浆粘性成分的来源、组成和功能仍是个谜，目前仅描述了精浆的一些生化和形态特征。在这篇综述中，我们重点关注目前对反刍动物和骆驼科动物精浆生理生化特性的认识。
