Erectile dysfunction (ED) is the inability of the penis to achieve and/or maintain an erection sufficient for satisfactory sexual intercourse.ED is an age-increasing disease, with a progressively higher prevalence among middle-aged and older men with increasing age. Mild erectile dysfunction (MSED) is mostly seen in young and middle-aged men. Patients are more concerned about their reproductive health because they are under more pressure for sexual and reproductive health; at the same time, they are widely receptive to new media and are more likely to raise awareness about ED treatment and seek early medical care. In contrast, middle-aged and elderly people have the highest prevalence of ED, or think that ED is a normal manifestation of aging, or due to the traditional type of deep influence, shy to seek medical treatment, but the number of people seeking medical treatment is lower. There is currently a lack of awareness of MSED among physicians, patients and society, often simply attributing it to psychological ED or a subnormal state, thus neglecting its significant value in predicting cardiovascular and related underlying diseases. Therefore, it is important to widely carry out prevention and health education about ED and its risk factors, and to pay attention to the screening and early diagnosis and treatment of MSED and related risk factors. Unhealthy diet and lifestyle habits, such as smoking and alcohol, little exercise, insufficient or poor quality sleep, and psychosomatic stress are risk factors for ED. Psychosocial factors have been considered as one of the important risk factors for ED in young adult men in China. The lack of school sex education leads to teenage sexual ignorance, sexual ignorance caused by sexual perception abnormalities (such as always feel their penis is short, poor sexual ability, masturbation is harmful to reproductive health, etc.), lack of confidence in sex, anxiety, depression and other adverse emotions cause male sexual psychological disorders, long-term will lead to ED. In addition, disharmonious sexual relations is an important risk factor for young adults ED, and the understanding and support of sexual partners help men The psycho-sexual and reproductive health of men. “Psychological” ED is a relative concept. With a deeper understanding of the etiology and pathogenesis of ED and advances in diagnostic techniques, many patients previously thought to have psychogenic ED have been found to have underlying organic damage. Vascular endothelial dysfunction is present in 73.1% of patients with psychogenic ED. Studies have found that chronic stressful pressure can cause metabolic syndrome, which further develops to cause vascular endothelial dysfunction and/or inflammatory damage, ultimately leading to the development of atherosclerosis and cardiovascular disease. This suggests that psychological ED left untreated for a long time can eventually migrate and develop into organic ED. Early pathological changes in the neurological, endocrine, vascular, and metabolic aspects affecting erection lead to MSED. therefore a comprehensive assessment of cardiovascular disease-related risk factors should be performed for patients clinically diagnosed with MSED. Vascular endothelial dysfunction is a common initiator and core pathogenesis of ED and cardiovascular disease. Because of the complex etiology of ED, many diseases can directly or indirectly affect erectile function; therefore, MSED patients often present to relevant specialties with co-morbidities such as premature ejaculation, chronic prostatitis/chronic pelvic pain syndrome, decreased libido, metabolic disorders, anxiety, depression, etc., while patients or/and physicians do not pay enough attention to the decrease in erectile function, thus neglecting MSED diagnosis and treatment and its associated cardiovascular and metabolic disease risk factors. The patient or/and the physician do not pay enough attention to the decline in erectile function, thus neglecting the MSED diagnosis and treatment and its associated cardiovascular, metabolic and risk factors. It is still recommended to use the IIEF EF scale for patient assessment, with a score of 17-25 being diagnostic of MSED, and the IIEF 5 scale, with a score of 17-21 being diagnostic of MSED, or in combination with the EHS scale, which can provide a more comprehensive assessment of the characteristics of MSED patients from different perspectives. Psychogenic ED and MSED are highly prevalent in young adult men. In the past, clinical practice considered that psychotherapy alone was sufficient for these patients, but it is now recognized that psychogenic ED can also lead to the development of organic ED through chronic stressful pressure in the long term. This mixed ED is difficult to cure through psychotherapy or pharmacotherapy alone, and the combined effect of the two is better than alone. Therefore, for such patients, the principle of individualized treatment emphasizing both pharmacotherapy and psychotherapy is emphasized, i.e., pharmacological intervention should be actively given early when self-lifestyle modification and psychotherapy are ineffective. In addition, the role of the female partner in ED treatment has been emphasized in recent years, and the understanding, encouragement and participation of the female partner in treatment are important motivations for ED patients to actively seek treatment. The participation of young adult ED patients and their spouses in treatment as a whole not only improves the treatment outcome of ED patients, but also improves partner sexual satisfaction, reflecting the advantages of holistic diagnosis and treatment of ED patients and their sexual partners. As for middle-aged and older men, a large number of studies in recent years have confirmed that ED is an early manifestation of cardiovascular disease. As an early stage of ED, MSED and cardiovascular disease share the same risk factors, and improving poor lifestyle and healthy diet, weight loss, smoking cessation, limiting alcohol consumption, and physical exercise have been shown to improve ED caused by low-grade inflammation, insulin resistance, and endothelial dysfunction. the principle of combining prevention and treatment in the MSED stage, actively screening for etiology and risk factors, and targeting Taking appropriate measures is conducive to moving the line of defense of major diseases forward. As an early stage of ED, MSED is associated with poor lifestyle. Psychosocial factors. Impaired vascular endothelial function, etc.; common risk factors exist with cardiovascular diseases and metabolic diseases. As the understanding of MSED continues to improve, its definition and assessment index will be further refined. Paying attention to the early diagnosis and treatment of MSED is of great practical significance for subdividing the stages of ED onset, deepening the research on the pathogenesis of ED, improving the level of early diagnosis of ED, maintaining the overall health of men, family happiness and social harmony, as well as for the early warning and prevention of major diseases.
