Brain hemorrhage can potentially affect a man’s sexual function. When the amount of brain hemorrhage is relatively large, the patient may show hemiplegia, aphasia, sensory impairment, and in severe cases, can show coma. For this type of patients, the main focus in the early stage is to save the patient’s life, while his sexual function is often affected. This is because the nerves that govern the patient’s sexual function are mainly innervated by the brain. When the amount of brain hemorrhage is relatively large, the regulation of such nerves will also be affected. If the amount of brain bleeding is relatively small, all aspects of the patient’s function will basically not be affected and sexual function is normal. Whether a brain hemorrhage affects a man’s sexual function depends largely on the size of the brain hemorrhage. For patients whose sexual function is affected, early intervention in rehabilitation therapy is needed. This is because early rehabilitation is conducive to maximum recovery of neurological function and thus maximum improvement of male sexual function.
