Main risk factors are: age, education level, anxiety, reactive depression, diabetes, heart disease, high blood pressure; disorders (hepatic failure, chronic renal failure, obesity, dyslipidemia); hormonal disorders (hypogonadism, hyperprolactinemia, hypo/hyperthyroidism); neuropathies (Alzheimer’s disease, Parkinson’s disease, degenerative diseases); urologic surgery, colorectal and vascular.
