Men will not experience menopause until they are about 50 years old. Menopause is related to the diminished testicular function in men, and also to the hypothalamus and pituitary gland, which mainly manifests itself as a decrease in physical fitness, that is, a decrease in physical strength and endurance, and is prone to fatigue, weakness, fat gain, abdominal obesity, loss of appetite, indigestion, constipation, and also vascular abnormalities, such as being particularly prone to excessive sweating, irritability, and palpitations. There is also hypogonadism, which generally manifests as loss of morning erectile function, decreased sexual function, decreased libido quality, decreased sperm quality, or absence of sperm, and erectile dysfunction. There are some manifestations of neurological and psychological factors, such as sleep disorders, with insomnia, anxiety, excessive dreaming, early sleep, early waking, memory loss, forgetfulness, poor concentration, depression, sadness, and poor self-perception. If the conditions described above occur, men need to go for some questionnaire assessment after the age of about 50 to see if it is really male menopause.
