ICV galanin-like peptide stimulates non-contact erections but not penile reflexes in adult, sexually experienced male rats

Within the central nervous system, galanin-like peptide (GALP) is found only within the arcuate nucleus of the hypothalamus. Intracerebroventricular (ICV) injection of GALP is known to have effects on feeding, and to also significantly increase GnRH-mediated LH secretion. Furthermore ICV GALP is known to stimulate fos production in the mPOA and the PVN and GALP profoundly stimulates male rat sexual behavior. It is not known if GALP ’s effects on sex behavior are due to an increase the motivational or mechanical aspects of sex.
