How old are men's menopause symptoms?

The concept of male menopause was first proposed by Western scholar Heller in 1939. Male menopause is called androgen decline syndrome in medicine, and it is mostly manifested in men aged 40~55. Because male menopause symptoms are not as typical as women, they are often mistaken for other diseases, so they are easily ignored. Male menopause symptoms are fatigue, insomnia, decreased sleep quality, osteoporosis, joint soreness, cardiovascular aging, etc. Some men will gain weight, mental symptoms are irritability, forgetfulness, lack of concentration, lack of interest in things, etc. In addition, perennial smoking, drinking, staying up late, unreasonable diet structure and other bad lifestyles may make menopause come early, so keep a healthy lifestyle and correct bad habits.
