Many people think that “menopause” is a woman’s business. In fact, men also have menopause. In this sense, both men and women have to go through menopause before entering old age. With the aging of our population, male menopause has become a major concern. Generally speaking, most men start menopause after the age of 40-55, but there are cases where men start as early as 35 or as late as 65, or even 70. However, not all men who enter menopause develop clinical symptoms, and according to statistics, 30% to 40% of middle-aged and older men may develop menopausal signs and symptoms to varying degrees. In this article, we will introduce the definition, symptoms and treatment of male menopause in detail. 1.Definition of male menopause It refers to a specific period of transition from middle age to old age, which is a transitional period based on the sudden change of hormone level, biochemical environment and psychological state in men’s body from flourishing to declining. If the change process is too intense, causing adverse effects on the function of multiple organ systems and reducing the quality of life, certain physical and mental abnormal symptoms or (and) signs will be manifested, with or without reduced serum testosterone levels, at which time it is called male menopause syndrome. Male menopause is caused by a variety of factors. In addition to the age factor, the following conditions are often present: high work-life stress; chronic diseases, such as diabetes, depression, cardiovascular disease, etc.; poor lifestyle, such as smoking, alcohol abuse, etc.; poor living environment; lack of physical activity; abdominal obesity, etc. 2.What are the symptoms of male menopause? (1) Symptoms of abnormal autonomic and vasodilation Hot flashes, bouts of sweating, insomnia, nervousness, etc. (2) Emotional and cognitive function symptoms Anxiety, drowsiness, poor self-perception, lack of motivation, diminished intelligence, decreased brain power, memory loss, slower thinking and reaction, depression, lack of self-confidence and unexplained fear, etc. (3) Decreased physical fitness and energy Decreased muscle mass, decreased muscle strength, weakness, loss of appetite, bone and joint pain, increased fat, abdominal obesity, loss of sexual hair, and other symptoms of decreased masculinity; easy fatigue, decreased ability to perform daily activities, and easy falls and injuries. (4) Decreased sexual function Decreased libido, decreased sexual activity, erectile dysfunction, decreased quality of orgasm, weakness of ejaculation, decreased semen volume, and no spontaneous erection in the morning. (5) Skeletal system In patients with fractures caused by osteoporosis, 7% to 30% have androgen deficiency. The mortality rate of femoral neck fractures in older men can be 30%, which is twice as high as that of menopausal women. (6) Others Mild anemia is more common in elderly men, one of the reasons is the decrease in serum testosterone level, and androgen supplementation is beneficial to correct the anemia. The symptoms of male menopause syndrome are very complex, and all these symptoms can be divided into three main categories. The first is psychoneurological symptoms, the second is circulatory and systemic symptoms, and the third is symptoms of sexual function and reproductive organs. The third category of symptoms is the most important and should be seen as the core symptoms, which are manifested as reduced sexual function, self-perceived erectile dysfunction, reduced and indifferent sexual desire, reduced erectile hardness or inability to get an erection, significantly reduced frequency of sexual intercourse, reduced ejaculatory strength or no ejaculation. The relationship between the above symptoms and the progressive decline in testicular function and T levels is still uncertain, so the diagnosis cannot be made solely on the basis of blood T, LH and FSH levels. 3.
