There are plenty of triggers, but poor circulation (that arrives with age) is a significant a single, together with large cholesterol, diabetic issues, exhaustion, some medications, and leisure drugs. Nitric oxide is critical because it is a vasodilator, allowing blood to flow into the corpora cavernosa. Viagra (and I suppose analogous meds) stop the NO from getting broken down also quickly.
