The etiology of erectile dysfunction can be divided into two categories: organic and psychological, with organic causes including vascular, neurological, endocrine, and penile factors.
However, it should be noted that these high-risk factors are only conclusions and possibilities obtained through statistical analysis, which does not mean that having these high-risk factors is bound to lead to erectile dysfunction.
1. Age
In 1992, the National Institutes of Health of the United States concluded that age is an indirect high-risk factor closely related to erectile dysfunction, and the likelihood of erectile dysfunction increases with age. According to foreign reports, the prevalence of erectile dysfunction in men aged 20 to 30 years is 7%, and the prevalence of erectile dysfunction in men aged 70 to 79 years is 57%.
Although the likelihood of erectile dysfunction increases with age, erectile dysfunction is not inevitable during the aging process.
2. Disease
① The proportion of patients with cardiovascular diseases such as heart disease and hypertension accompanied by erectile dysfunction is 39% and 15%, respectively. Moreover, erectile dysfunction may be a precursor of systemic atherosclerosis.
② Diabetes is one of the most closely related diseases with erectile dysfunction. the prevalence of erectile dysfunction in diabetes patients is 23%~75%. Those who have suffered from diabetes for more than 10 years are twice as likely to have erectile dysfunction as those who have suffered from diabetes for less than 5 years. In addition, poor blood sugar control and smoking both increase the likelihood of morbidity.
③ The proportion of chronic renal insufficiency accompanied by erectile dysfunction is over 40%.
④ In hyperlipidemia, the higher the total cholesterol in serum and the lower the high lipoprotein, the greater the likelihood of erectile dysfunction.
⑤ Multiple sclerosis, stroke, demyelinating disease, Alzheimer's disease, and other neurological disorders are all related to erectile dysfunction.
⑥ Endocrine diseases such as hypopituitarism, hypogonadism, hyperprolactinemia, adrenal diseases, hyperthyroidism, and hypothyroidism are related to erectile function.
⑦ The probability of prostate and penis diseases accompanied by erectile dysfunction is over 40%.
⑧ The probability of ulcerative disease accompanied by erectile dysfunction is 18%. Arthritis, allergies, alcoholic liver cirrhosis, and chronic obstructive pulmonary disease are closely related to erectile dysfunction.
3. Psychological factors
Mental disorders such as schizophrenia, depression, and medications for treating depression are all associated with erectile dysfunction. 50% to 90% of depressive patients have apathy of sexual desire; On the other hand, sexual dysfunction often causes mental disorders such as depression and anxiety.
"Using diuretics, antihypertensive drugs, drugs for treating heart disease, tranquilizers, antidepressants, hormones, anticholinergics, and drugs for treating ulcers can all cause erectile dysfunction.".
5. Poor lifestyle
① Smoking. The prevalence of complete erectile dysfunction in smoking and non smoking heart disease patients was 56% and 21%, respectively; The prevalence of complete erectile dysfunction in hypertensive patients who smoke and who do not smoke is 20% and 8.5%, respectively.
② Excessive drinking. Alcohol has a saying of "increasing libido and reducing libido". Foreign studies have shown that the prevalence of erectile dysfunction in alcoholic and non alcoholic liver disease patients is 70% and 25%, respectively. And half of people still fail to recover their erectile function after years of abstinence from alcohol.
③ Drug use. Some studies have shown that the prevalence of erectile dysfunction among heroin addicts is 32.2%.
"Injuries, surgical spinal cord injuries, or surgery, pelvic fractures combined with urethral trauma, transabdominal perineal radical resection of rectal cancer, retroperitoneal lymphadenectomy, aortic reconstruction, pelvic radiation therapy for prostate cancer, and any other trauma or surgery that impairs penile nerve innervation and vascular supply can easily cause erectile dysfunction.". Therefore, surgeons should continuously improve surgical techniques and techniques to prevent the occurrence of iatrogenic erectile dysfunction.
