男性更年期綜合徵（Male Menopause Syndrome）的中醫療法

According to the research and investigation of the World Health Organization, male older than 30 years old would decrease androgen by an average of about 1%-2% per year. Measured by the metabolism of hormone exam, it is found that its clearance rate and production velocity are decreased with the increasing of age in the middle aged and senior age male. The amount and concentration of androgen are decreased in the tissue. After investigating on male around 25-70 year old it is found that the level of androgen in 70 year old men is only 10% compared with 25 year old men. It is estimated that the level of androgen in above 75 year old men is about equivalent to 9 year old boys. As for 40-90 year old men, the level of testosterone drops by an average of about 1%-2% per year, and total reduction is up to 30%-50%.Compared with the menopause in women, the occurrence lime of male climacterium is relatively earlier which , generally begins at 40 - 50 years old, and lasts longer until 60 - 65 years old, even older. Almost all men can be influenced with variant degree. According to the research statistics, about 40% of 40 - 70 years old men will have the symptoms of climacterium. Most of all men will not have significant symptoms of climacterium throughout the life. The declination for the level of androgen is mainly caused by the functional decay of Leydig cell. When the level of androgen in lower than 300 ng/dl, the men will start to appear the depletion of sexual desire, fatigue, dispirited, lessening of erection times, and degradation of sexual life.The male climacterium is an aging phenomenon, which is also a new beginning of physiological stage. Most symptoms are obvious in female menopause, but it is not distinct in male climacterium. It is often neglected due to the dash development of male career is often occurred in this stage, therefore it is often considered to be caused by troublesome in career or family factor. The clinical symptoms are the degradation of sexual function, mood alteration, neural and vascular symptoms and the reduction of virilescence sign etc. Clinically male patients often interpret the climacteric symptoms, such as irritation, depression, and insomnia, etc are caused by troublesome career, and the instability, fatigue, and the reduction of sexual function are caused by family factor. Patients even neglected the symptoms directly and failed to see the doctor, so it bothers many aging male. In 1994, Morales and Lunenfeld proposed the concept and definition of ”Male climacteric syndrome - patients with Partial Androgen Deficiency of the Aging Male (PADAM)”. The PADAM is defined as the clinical physiological and psychological symptoms caused by the deficiency of androgen due to aging.Because the influence of aging population trend and various corresponding factors, the male climacteric syndrome affects many aging male gradually and extensively. From the viewpoint of public health and preventive medicine, people do not pay attention to the male climacteric syndrome like the female menopausal syndrome. But with the development of male medical science, the medical workers and people should seek and pay enough understanding and attention to the male menopause syndrome, and enable it to get prompt, effective treatment and prevention. Meanwhile, how to help the men to pass through the male climacteric syndrome is one of the major research topic of male medical science at current time.
