摘要

生酮饮食（KD）已显示出对一系列神经精神疾病的治疗潜力；然而，有关 KD 对健康人群行为影响的数据还不够充分。在这里，我们研究了 KD 对以 KD 或标准饲料（SD）饲养的年轻成年雄性 Sprague-Dawley 大鼠性行为的影响。我们发现，与 SD 雄性大鼠相比，KD 雄性大鼠表现出更高的骑乘率、更高的插入率（仅第三和第四次测试）以及更低的射精可能性（仅第二次测试）。因此，在KD雄性动物中，性刺激处理过程中依赖于经验的变化可能没有那么有效地发生，从而导致观察到的交配顺序改变。

Alterations to the copulatory sequence in young adult male Sprague–Dawley rats administered a ketogenic diet

Ketogenic diets (KDs) have shown therapeutic potential for a range of neuropsychiatric disorders; however, there is insufficient data regarding the behavioral impacts of KDs in healthy populations. Here, we examined the impact of a KD on sexual behavior in young adult male Sprague-Dawley rats maintained on either a KD or standard chow diet (SD). We found that KD males exhibited higher mount rates, higher intromission rates (third and fourth tests only), and lower ejaculation likelihood (second test only) compared to SD males. Consequently, it may be that experience-dependent changes in the processing of sexual stimuli are not occurring as efficiently in KD males, thereby yielding the observed copulatory sequence alterations.

期刊介绍： Physiology & Behavior is aimed at the causal physiological mechanisms of behavior and its modulation by environmental factors. The journal invites original reports in the broad area of behavioral and cognitive neuroscience, in which at least one variable is physiological and the primary emphasis and theoretical context are behavioral. The range of subjects includes behavioral neuroendocrinology, psychoneuroimmunology, learning and memory, ingestion, social behavior, and studies related to the mechanisms of psychopathology. Contemporary reviews and theoretical articles are welcomed and the Editors invite such proposals from interested authors.
