“ During sexual arousal, nitrous oxide (NO) is discharged from spunk terminals and endothelial cells in the principal sum cavernosum.
NO activates guanylate cyclase to exchange
guanosine triphosphate (GTP) into cycle guanosine monophosphate (cGMP),
triggering a cGMP-pendant shower of events. The accumulation of cGMP leads to smooth-muscularity slackening in the corpus cavernosum and increased
ancestry stream to the phallus. http://lm360.us/ ”
