AbstractIschaemic priapism is a devastating urological condition that has the potential to cause permanent erectile dysfunction. The disorder has been associated with numerous medical conditions and the use of pharmacotherapeutic agents. The aetiology is idiopathic in a number of cases. There are two prior case reports of the association of ischaemic priapism and glucose-6-phosphate dehydrogenase (G6PD) deficiency. We report on a third case of priapism associated with G6PD deficiency and review recently described molecular mechanisms of increased oxidative stress in the pathophysiology of ischaemic priapism. The case report of a 32-year old Afro-Caribbean male with his first episode of major ischaemic priapism is described. Screening for common causes of ischaemic priapism, including sickle cell disease was negative. Glucose-6-phosphate dehydrogenase deficiency was discovered on evaluation for priapism. Penile aspiration was performed and erectile function was good post treatment.Glucose-6-phosphate dehydrogenase deficiency is a cause for ischaemic priapism and should be a part of the screening process in idiopathic causes of the disorder. Increased oxidative stress occurs in G6PD deficiency and may lead to priapism.
