A sexually dimorphic peptidergic system in the lower spinal cord controlling penile function in non-human primates

Experimental animal study.Although a population of gastrin-releasing peptide (GRP) neurons in the lumbar spinal cord has an important role in erection and ejaculation in rats, little information exists on this GRP system in primates. To identify the male-specific GRP system in the primate spinal cord, we studied the lumbosacral cord in macaque monkeys as a non-human primate model.University laboratory in Japan.To determine the gene sequence of...
