Most erection due to sexual stimulation never approach four to six hours. Priapism is not associated with sexual excitement, at least not initially, and the erection does not subside after ejaculation. Priapism can occur in all age groups, including newborns. Most cases of priapism are clustered between two age groups: between the ages of five to ten and twenty to fifty years. Priapism constitutes a true urologic emergency. Men often joke that they wish they could have a permanent erection, but in reality, men are extremely miserable when this actually happens.
