The control of bovine male reproduction is a finely orchestrated system. However, the mechanism has already been predetermined by the bull's genetic makeup and, to a lesser extent, the environment. Although the endocrine system appears robust, excessive pressures can inhibit or arrest the process. Similarly, structural limits to the bull's anatomy exist, and exceeding them can result in permanent damage. Hence, a thorough understanding of the anatomy and physiology allows successful management of the breeding bull.
公牛雄性生殖的控制是一个精心编排的系统。然而，该机制已经由公牛的基因构成预先决定，并且在较小程度上受环境影响。尽管内分泌系统看似强大，但过大的压力会抑制或阻止这一过程。同样，公牛的解剖结构存在结构限制，超过这些限制可能会导致永久性损伤。因此，全面了解解剖学和生理学有助于成功管理种公牛。
