| Animals change their biological activities depending on their nutritional state. Reproductive functions, including sexual behavior, are suppressed under low-energy conditions; however, the underlying neuronal mechanism is poorly understood. Neuropeptide Y (NPY) is an orexigenic molecule released in response to low-energy conditions and has an inhibitory effect on sexual behavior. We examined how NPY is involved in energy state-dependent regulation of male sexual behavior. Mounting, intromission, and ejaculation were evaluated as parameters of sexual behavior. Almost all parameters indicated that fasting for 24 h suppressed male sexual behavior. Intracerebroventricular injection of NPY inhibited sexual behavior in males that free-fed for 8 h following 24-h... |
