Priapism refers to a persistent erection that occurs in the absence of sexual stimulation, and lasts for more than 6 hours. Priapism is primarily a condition which affects men, although there are some rare cases of female priapism, where the clitoris becomes engorged for extended periods of time. Priapism can be caused by a variety of factors, including medication, illness, physical trauma. There are several effective treatments for priapism, but it is crucial that treatment happens in a timely manner, as prolonged priapism can result in permanent damage.
