Sexual behavior dysfunction unaccompanied by detectable physical or endocrine abnormality is an important cause of reproductive failure among domestic stallions. Several authors have suggested that such dysfunction may be psychogenic, related to negative experience associated with intense handling and training. An experimental model of experience-related dysfunction was developed by exposing pony stallions to erection-contingent aversive conditioning. This resulted in rapid, specific suppression of sexual arousal and response similar to spontaneously occurring dysfunction. Subsequently, treatment with a CNS-active benzodiazepine derivative (diazepam) reversed these effects.
性行为功能障碍且未伴有可检测到的身体或内分泌异常是家养种马繁殖失败的一个重要原因。几位作者认为，这种功能障碍可能是心因性的，与与高强度处理和训练相关的负面经历有关。通过使小马种马接受与勃起相关的厌恶条件反射，建立了一种与经验相关的功能障碍的实验模型。这导致了性唤起和反应的快速、特异性抑制，类似于自然发生的功能障碍。随后，使用一种中枢神经系统活性苯二氮䓬衍生物（地西泮）进行治疗可逆转这些效应。
