Erectile dysfunction is not simply considered a natural part of aging, although as a man ages, his sexual abilities change. Nearly half of men over the age of 50 report some degree of erectile dysfunction, but achieving an erection and a satisfying sex life is quite possible even in your 90s. Erectile dysfunction is defined as the inability to achieve and maintain an erection for sexual intercourse. There are a number of known causes of the condition, some of which are psychologically based. Stress, anxiety, depression, problems in the relationship with the intimate partner are at the root of the problem. In the medical group are heart problems, prostate cancer or surgery for this disease and some physical causes. Factors include even lack of sleep and rest. Erectile dysfunction can develop as a result of taking medications that affect the hormonal background, blood flow or the nervous system. Antidepressants, drugs against high blood pressure, enlarged prostate, heart disease and others have such an effect. NEWS_MORE_BOX The presence of some diseases can also be unfavorable for sex life. This category includes diabetes and obesity, as well as hypertension. Smoking, alcohol abuse and low testosterone should also be added to the risk factors. The hormonal background is of key importance for good sex and sexual desire. In men, low testosterone in this aspect is indeed a problem. Such an assumption can be confirmed or rejected after a blood test. It should not be overlooked that erectile dysfunction is sometimes an early sign of cardiovascular disease, which forms a second reason to consult a doctor and undertake the necessary tests to establish heart health and assess the risk of heart attack and stroke.
