Summary— A group of 26 patients who were operated upon for idiopathic priapism between 1972 and 1986 were classified according to the date on which they attended hospital. During the same 15‐year period 150 patients with penile cancer were treated and they served as controls. The data were analysed for circannual rhythmicity (365.25 days = 360° and 0°= 22 December. This revealed a significant circannual rhythmicity in the occurrence of idiopathic priapism, with the acrophase located on 2 August. There was a significantly higher incidence of idiopathic priapism between April and September.
