Sexual physiological dysfunction may be caused by certain diseases of the body, as well as psychological and environmental factors. 1. Diseases: Hypogonadism, thyroid diseases (hypothyroidism, hyperthyroidism), adrenal gland lesions (Cushing’s syndrome), injuries after pelvic surgeries (prostate and bladder surgeries), and diseases of the penis (Peyronie’s disease) and other disorders can cause sexual physiological disorders. 2. Psychological factors: high stress in life or work, problems in the relationship between husband and wife, repressed sexual behavior and other negative emotions can also occur. 3. Environmental factors: not having a place to relax and be private, or feeling tired due to busy work can also occur. When sexual dysfunction occurs, it is recommended to go to the hospital to find out the cause and get timely treatment.
