Ejaculatory disorders of the stallion seem to occur more frequently than hitherto accepted. The condition is manifested differently in individual stallions from normal copulation without ejaculation to an abnormal pattern of copulation without or with occasional ejaculation. The condition is probably caused by a functional disturbance of the nervous mechanism which controls the ejaculatory process, and may be caused by environmental or other factors. Eleven cases of ejaculatory disorders in normal healthy stallions were investigated and three of these animals recovered after simple correction of environmental factors, including the number of mares served. Of the eight stallions which did not respond to environmental changes, one recovered after treatment with pilocarpine and one after treatment iwth ephedrine. Possible causes of failure of the nervous regulation of the reproductive tract are discussed.
种马射精障碍的发生似乎比以往所认为的更为频繁。这种情况在不同种马身上表现各异，从正常交配但不射精到异常的交配模式（不射精或偶尔射精）。该病症可能是由控制射精过程的神经机制功能紊乱引起的，也可能是由环境或其他因素导致的。对11例健康正常种马的射精障碍病例进行了调查，其中3只动物在简单纠正环境因素（包括配种母马数量）后康复。在8只对环境变化无反应的种马中，1只在使用毛果芸香碱治疗后康复，1只在使用麻黄碱治疗后康复。文中讨论了生殖道神经调节失败的可能原因。
