With the aging of the human body, many middle-aged and elderly people feel that their sexual function is declining, with common manifestations such as low libido, reduced or absent “morning erection”, poor erection hardness, inability to complete sex life and so on. This is a common clinical disease in male medicine – penile erectile dysfunction. Some people feel that the age is so old, the lady also did not ask for it, no it is not. This idea is not right, from the medical point of view, penile erection can not be simply understood as a problem with sexual function. The good or bad erection is a sign of good or bad physical condition, just like a flag, the flag is erect, the body foundation is good; the flag is down, the body foundation is bad. Research has shown that many diseases before the onset of penile erection has been “early warning”, typically most patients with coronary heart disease about 2 years before the onset of the penile erectile dysfunction is commonly manifested. Therefore, we are not just for “sex” and treatment of sexual function, but in the maintenance of the body at the same time to treat the sexual function. Winter is the best time to recuperate and replenish your body, so middle-aged and elderly people should not miss the opportunity to visit a male clinic in time.
