Stroke is a major disabling and fatal disease worldwide.There are many studies on neurological deficits and cognitive impairment after stroke,but there are few studies on sexual dysfunction,which is an important part of patients'quality of life.Studies have shown that male sexual dysfunction following stroke is very common,such as loss of libido,erectile dysfunction and ejaculatory weakness.Among them,young male stroke patients have particularly high requirements for quality of life and are ashamed to speak when they have secondary dysfunction.Related knowledge and degree of attention of medical staff are also relatively less.The location and area of stroke and the occurrence and development process of the disease may affect the sexual function of patients.Its etiology roughly includes both organic and functional aspects.Further study of post-stroke sexual dysfunction and strengthening the diagnosis and treatment of sexual dysfunction in stroke patients should be included in the category of stroke rehabilitation.
