After spermatogenesis, testicular spermatozoa are not able to fertilize an oocyte, they must undergo sequential maturational processes. Part of these essential processes occurs during the transit of the spermatozoa through the male reproductive tract. Since the sperm become silent in terms of translation and transcription at the testicular level, all the maturational changes that take place on them are dependent on the interaction of spermatozoa with epididymal and accessory gland fluids. During the last decades, reproductive biotechnologies applied to bovine species have advanced significantly. The knowledge of the bull reproductive physiology is really important for the improvement of these techniques and the development of new ones. This paper focuses on the importance of the sperm interaction with the male reproductive fluids to acquire the fertilizing ability, with special attention to the role of the membranous vesicles present in those fluids and the recent mechanisms of protein acquisition during sperm maturation.
精子发生后，睾丸精子无法使卵母细胞受精，它们必须经历一系列成熟过程。这些重要过程的一部分发生在精子通过雄性生殖道的过程中。由于精子在睾丸水平上翻译和转录方面处于静止状态，它们发生的所有成熟变化都依赖于精子与附睾和附属腺液的相互作用。在过去几十年中，应用于牛种的生殖生物技术有了显著进展。公牛生殖生理学知识对于改进这些技术和开发新技术非常重要。本文重点关注精子与雄性生殖液相互作用以获得受精能力的重要性，特别关注这些液体中存在的膜性小泡的作用以及精子成熟过程中蛋白质获取的最新机制。
