The main causes of frigidity in women at the age of forty can be categorized into physical and psychological factors. Physical factors mainly consider the body’s hormone level changes or organic lesions and other reasons. With age, hormone levels in the body will gradually decline, leading to low libido. Some patients suffer from underlying diseases, such as diabetes and gynecological diseases, which lead to decreased sensory excitability of peripheral nerves, thus making sexual function impaired. Psychological factors are mainly caused by themselves or the outside world, some patients are in a state of long-term anxiety, depression, resulting in mental influence, and thus too much resistance in sexual life, resulting in frigidity. A small number of patients suffer from sexual trauma, resulting in fear of sexual partners. External factors are mainly considered to be long-term bad habits such as alcoholism, drug abuse and other neurological disorders, or sexual relations with sexual partners in the long-term disharmony, can not get comfortable, and in the long run lead to the formation of sexual frigidity. Sexual frigidity should be timely to the appropriate specialties, improve the necessary checks, while strengthening exercise, maintain a light diet, regular life, and maintain a happy mood.
