The rat lumbar spinal cord contains the testosterone-dependent spinal nucleus of the bulbocavernosus (SNB), whose motoneurons innervate perineal muscles involved in copulatory reflexes. In normal males, SNB dendrites grow exuberantly through the first 4 weeks postnatally. This growth is steroid-depe
