Summary: Oxytocin directly activates SEG (Spinal Ejaculation Generator)/GRP (Gastrin-Releasing Peptide) neurons via OXTRs (Oxytocin Receptors) and influences male sexual function in the rat lumbar spinal cord.
Usage: Oxytocin-SAP (4 or 40 ng) was infused slowly into the L3 and L4 spinal cord. Blank-SAP was used as control.
