The total prevalence of ED (erectile dysfunction) among men in mainland China has reached 26.1%, with a prevalence of 40.2% among people over 40 years of age, while the treatment-seeking rate among patients is only 17%. Sexual confidence, healthy sexual pride and self-esteem have been included in the new goals of ED treatment. So, what factors can cause erectile dysfunction? Here are the factors that may cause the onset of erectile dysfunction: 1, drugs may lead to ED Some drugs may also lead to inactivity. For example, drugs for the treatment of prostate (sometimes also used to treat hair loss). Because of its anti-androgenic effect, some people eat will have a bad erection; other drugs such as anti-anxiety depression drugs, sedatives. People taking antidepressants may benefit if they have a bad erection after it is recommended to adjust their medication to trazodone. Anti-hypertensive drugs because they can lower blood pressure, reduce penile perfusion pressure, and make the penile artery blood supply is insufficient to cause impotence. 2, diabetic patients are prone to ED Dou Jingtao, Department of Endocrinology, PLA General Hospital, introduced that 40% to 60% of diabetic patients are accompanied by varying degrees of sexual function decline, of which men are mostly manifested as erectile dysfunction (ED). Therefore, diabetic ED patients should actively prevent and treat ED while adhering to glucose-lowering and antihypertensive treatment, and can take some drugs that adjust plant nerve function and improve body microcirculation. It is best to visit a specialist physician for a clear diagnosis. 3, no sex will also suffer from ED There are many people believe that ED is a disease of people who have sex, no sex partners and sex, there is no ED problem. Clinic is often asked: no sex, but just feel bad penile erection, the need for treatment? Clinical observation shows that if there is no sex for more than three months and no satisfactory erection, it may lead to the decline of male erectile function and penile corpus cavernosum atrophy, which leads to ED. we call it “asexual ED”. The patient not only affects his marriage and other normal life, but also aggravates the ED condition. 4, excessive cycling increases the risk of ED A study of cycling and not cycling two groups of data for comparison, the results show that, after excluding age, smoking, depression, chronic diseases, physical condition and other factors, cycling more than 3 hours a week is an independent risk factor for ED, if less than 3 hours is not relevant to ED, the reason may be moderate cycling exercise cardiovascular exercise, thus protecting erectile function. To avoid the narrow seat on the perineum tissue pressure, the simplest way, is the front of the seat down 10 degrees, the front of the pressure will be 44% less than the horizontal, so that the pressure on the male perineum will be significantly reduced. In addition, to try to control the cycling time, should do 1 hour ride, push 10 minutes. 5, severe anemia or the emergence of ED The impact of anemia on sexual function is multifaceted, such as anemia, blood in the red blood cells reduced, hemoglobin concentration is reduced, its oxygen-carrying capacity will be weakened, resulting in tissue, cells in the supply of oxygen is reduced, the function of sexual organs will naturally occur abnormally, severe anemia can appear impotence (ED), premature ejaculation, reduced libido and other sexual function decline in performance.
