For some patients, the headache begins suddenly, often at orgasm. In two thirds of cases, it is bilateral, and unilateral in the rest. The pain lasts from one minute to 24 hours with severe intensity, or as long as 72 hours with mild intensity. Its occurrence is unpredictable, and may not follow every sexual act. Previous editions of the ICHD divided the condition into two subforms, preorgasmic headache and orgasmic headache.
