Age is an indirect high-risk factor closely related to impotence, and the likelihood of impotence increases with age. According to foreign reports, the prevalence rate of impotence in men aged 20-30 is 7%, and the prevalence rate of impotence in men aged 70-79 is 57%. Although the likelihood of impotence increases with age, impotence is not inevitable during the aging process.
Diabetes is one of the most closely related diseases with impotence. the prevalence of impotence in diabetes patients is 23%~75%. People who have suffered from diabetes for more than 10 years are twice as likely to have impotence 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.
Endocrine diseases such as hypopituitarism, hypogonadism, hyperprolactinemia, adrenal diseases, hyperthyroidism, and hypothyroidism are related to erectile function.
Smoking. The prevalence of complete impotence in smoking and non smoking patients with heart disease was 56% and 21%, respectively; The prevalence of complete impotence in smoking and non smoking hypertensive patients was 20% and 8.5%, respectively.
Any trauma or surgery that impairs nerve innervation and blood vessel supply, such as spinal cord injury or surgery, pelvic fracture with urethral trauma, transabdominal perineal radical resection of rectal cancer, retroperitoneal lymphadenectomy, aortic reconstruction, prostate cancer, pelvic radiotherapy, etc., can easily cause impotence. Therefore, surgeons should continuously improve their surgical techniques and techniques to prevent the occurrence of iatrogenic impotence.
